Making a copy of a existing database with out data in it - mysql

I want to copy a Database without copying its data, I mean I just want to copy the stucture and tables and foreign key and ... not the data in it.
The answer is here but I do not know where should I copy it ? In shell? In workbench? In query?
I entered it in query in workbenck and it has error !
Thank you in advance!
Edit
When I run it in my mysql shell I get this:
MySQL JS > mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
SyntaxError: Unexpected identifier.

You'll need to run it on the command line for your OS (not the shell for MySQL as you tried earlier).
Under Linux (including Macs) it would look something like:
smm#smm-HP-ZBook-15-G2:~/$ mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
Under Windows:
C:\> mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
This is assuming mysqldump is in the PATH for your command line (it isn't if you get a command not found error). How to use a command line and set up the PATH depends on the OS and is beyond the scope of this answer.

1) Create dump file

MySQL 5.7 - Export Dump [duplicate]

I have a database that is quite large so I want to export it using Command Prompt but I don't know how to.
I am using WAMP.
First check if your command line recognizes mysql command. If not go to command & type in:
set path=c:\wamp\bin\mysql\mysql5.1.36\bin
Then use this command to export your database:
mysqldump -u YourUser -p YourDatabaseName > wantedsqlfile.sql
You will then be prompted for the database password.
This exports the database to the path you are currently in, while executing this command
Note: Here are some detailed instructions regarding both import and export
Simply use the following command,
For Export:
mysqldump -u [user] -p [db_name] | gzip > [filename_to_compress.sql.gz]
For Import:
gunzip < [compressed_filename.sql.gz] | mysql -u [user] -p[password] [databasename]
Note: There is no space between the keyword '-p' and your password.
Well you can use below command,
mysqldump --databases --user=root --password your_db_name > export_into_db.sql
and the generated file will be available in the same directory where you had ran this command.
You could find more on the official reference for mysqldump: Import Export MySQL DB
Note: use --databases instead of --database since the last one is no more supported.
Enjoy :)
First of all
open command prompt then open bin directory in cmd (i hope you're aware with cmd commands)
go to bin directory of your MySql folder in WAMP program files.
run command
mysqldump -u db_username -p database_name > path_where_to_save_sql_file
press enter system will export particular database and create sql file to the given location.
i hope you got it :)
if you have any question please let me know.
Go to command prompt at this path,
C:\Program Files (x86)\MySQL\MySQL Server 5.0\bin>
Then give this command to export your database (no space after -p)
mysqldump -u[username] -p[userpassword] yourdatabase > [filepath]wantedsqlfile.sql
Locate your mysql instance with:
which mysql
If this is correct then export with the following (else navigate to the mysql instance in your mamp folder in bin):
mysqldump -u [username] -p [password] [dbname] > filename.sql
And if you wish to zip it at the sametime:
mysqldump -u [username] -p [password] [db] | gzip > filename.sql.gz
You can then move this file between servers with:
scp user#xxx.xxx.xxx.xxx:/path_to_your_dump/filename.sql.gz your_detination_path/
(where xxx.xxx.xxx.xxx is the server IP address)
And then import it with:
gunzip filename.sql.gz | mysql -u [user] -p [password] [database]
To export PROCEDUREs, FUNCTIONs & TRIGGERs too, add --routines parameter:
mysqldump -u YourUser -p YourDatabaseName --routines > wantedsqlfile.sql
The problem with all these solutions (using the > redirector character) is that you write your dump from stdout which may break the encoding of some characters of your database.
If you have a character encoding issue. Such as :
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ...
then, you MUST use -r option to write the file.
MySQL
mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump.sql
Using Docker
docker exec --rm -v $pwd:dump -it mysql:5:7 mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump/dump.sql
Note: this mounts the current path as dump inside the instance.
We found the answer here
Conversely, don't use < to import your dump into your database, again, your non-utf8 characters may not be passed; but prefer source option.
mysql -u user -pYourPasswordYouNowKnowHow --default-character-set=utf8 your-database
mysql> SET names 'utf8'
mysql> SOURCE dump.sql
Give this command to export your database, this will include date as well
mysqldump -u[username] -p[userpassword] --databases yourdatabase | gzip > /home/pi/database_backup/database_`date '+%m-%d-%Y'`.sql.gz
(no space after -p)
I have installed my wamp server in D: drive so u have to go to the following path from ur command line->(and if u have installed ur wamp in c: drive then just replace the d: wtih c: here)
D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button and select the currently working mysql version on your server if you have more than one mysql versions)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysqldump -u root -p password db_name > "d:\backupfile.sql"
here root is user of my phpmyadmin
password is the password for phpmyadmin so if u haven't set any password for root just nothing type at that place,
db_name is the database (for which database u r taking the backup)
,backupfile.sql is the file in which u want ur backup of ur database and u can also change the backup file location(d:\backupfile.sql) from to any other place on your computer
mysqldump -h [host] -p -u [user] [database name] > filename.sql
Example in localhost
mysqldump -h localhost -p -u root cookbook > cookbook.sql
mysqldump --no-tablespaces -u username -p pass database_name > db_backup_file.sql
Syntax
(mysqldump.exe full path) -u (user name) -p (password) (database name) > (export database file full path)
Example
c:>d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe -u root -p mydbname > d:\mydb.sql
where d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe will be your actual mysqldump.exe path, mydbname is the name of database which you want to export and d:\mydb.sql is the path where you want to store the exported database.
For import:
mysql -u db_username -p newFileName < databasName.sql
For export:
mysqldump -u db_username -p databasName > newFileName.sql
I have used wamp server. I tried on
c:\wamp\bin\mysql\mysql5.5.8\bin\mysqldump -uroot -p db_name > c:\somefolder\filename.sql
root is my username for mysql, and if you have any password specify it with:
-p[yourpassword]
Hope it works.
For windows OS :
When you get error 1064 mysql (42000) while trying to execute mysqldump command, exit from current terminal. And execute mysqldump command.
mysql>exit
c:\xampp\mysql\bin>mysqldump -uroot -p --databases [database_name] > name_for_export_db.sql
I was trying to take the dump of the db which was running on the docker and came up with the below command to achieve the same:
docker exec <container_id/name> /usr/bin/mysqldump -u <db_username> --password=<db_password> db_name > .sql
Hope this helps!
mysql -u -p databaseName>fileToPutDatabase
Login in your databse server and then hit the below command:-
mysql -u username -p databasename > exportfilename.sql
Then it will ask for password Enter the password and hit enter,it will take some time your database will be exported.
You can use this script to export or import any database from terminal
given at this link: https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh
echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo
mysqldump_location=/opt/lampp/bin/mysqldump

if [ "$action" == "export" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
echo
else
echo -e "Using default location of mysqldump\n"
fi
read -p 'Give the name of database in which you would like to export: ' db_name
read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
$mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysql that you want to use: ' mysql_location
echo
else
echo -e "Using default location of mysql\n"
fi
read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
read -p 'Give the name of database in which to import this file: ' db_name
$mysql_location -u $u_name -p $db_name < $sql_file
else
echo "please select a valid command"
fi

How do I import an SQL file using the command line in MySQL?

I have a .sql file with an export from phpMyAdmin. I want to import it into a different server using the command line.
I have a Windows Server 2008 R2 installation. I placed the .sql file on the C drive, and I tried this command
database_name < file.sql
It is not working. I get syntax errors.
How can I import this file without a problem?
Do I need to create a database first?
Try:
mysql -u username -p database_name < file.sql
Check MySQL Options.
Note 1: It is better to use the full path of the SQL file file.sql.
Note 2: Use -R and --triggers with mysqldump to keep the routines and triggers of the original database. They are not copied by default.
Note 3 You may have to create the (empty) database from MySQL if it doesn't exist already and the exported SQL doesn't contain CREATE DATABASE (exported with --no-create-db or -n option) before you can import it.
A common use of mysqldump is for making a backup of an entire database:
mysqldump db_name > backup-file.sql
You can load the dump file back into the server like this:
Unix
mysql db_name < backup-file.sql
The same in the Windows command prompt:
mysql -p -u [user] [database] < backup-file.sql
PowerShell
cmd.exe /c "mysql -u root -p db_name < backup-file.sql"
MySQL command line
mysql> use db_name;
mysql> source backup-file.sql;
Regarding the time taken for importing huge files: most importantly, it takes more time because the default setting of MySQL is autocommit = true. You must set that off before importing your file and then check how import works like a gem.
You just need to do the following thing:
mysql> use db_name;
mysql> SET autocommit=0 ; source the_sql_file.sql ; COMMIT ;
Among all the answers, for the problem above, this is the best one:
mysql> use db_name;
mysql> source file_name.sql;
Easiest way to import into your schema:
Login to mysql and issue below mention commands.
mysql> use your_db_name;
mysql> source /opt/file.sql;
We can use this command to import SQL from the command line:
mysql -u username -p password db_name < file.sql
For example, if the username is root and password is password. And you have a database name as bank and the SQL file is bank.sql. Then, simply do like this:
mysql -u root -p password bank < bank.sql
Remember where your SQL file is. If your SQL file is in the Desktop folder/directory then go the desktop directory and enter the command like this:
cd ~/Desktop
mysql -u root -p password bank < bank.sql
And if you are in the Project directory and your SQL file is in the Desktop directory. If you want to access it from the Project directory then you can do like this:
cd ~/Project
mysql -u root -p password bank < ~/Desktop/bank.sql
If you already have the database, use the following to import the dump or the sql file:
mysql -u username -p database_name < file.sql
if you don't you need to create the relevant database(empty) in MySQL, for that first log on to the MySQL console by running the following command in terminal or in cmd
mysql -u userName -p;
And when prompted provide the password.
Next, create a database and use it:
mysql>create database yourDatabaseName;
mysql>use yourDatabaseName;
Then import the sql or the dump file to the database from
mysql> source pathToYourSQLFile;
Note: if your terminal is not in the location where the dump or sql file exists, use the relative path in above.
Open the MySQL command line
Type the path of your mysql bin directory and press Enter
Paste your SQL file inside the bin folder of mysql server.
Create a database in MySQL.
Use that particular database where you want to import the SQL file.
Type source databasefilename.sql and Enter
Your SQL file upload successfully.
A solution that worked for me is below:
Use your_database_name;
SOURCE path_to_db_sql_file_on_your_local;
While most answers here just mention the simple command
mysql -u database_user -p [db_name] < database_file.sql
today it's quite common that databases and tables have utf8-collation where this command is not sufficient.
Having utf8-collation in the exported tables it's required to use this command:
mysql -u database_user -p --default-character-set=utf8 [db_name] < database_file.sql
An according export can be done with
mysqldump -u database_user -p --default-character-set=utf8 [db_name] > database_file.sql
Surely this works for other charsets too, how to show the right notation can be seen here:
https://dev.mysql.com/doc/refman/5.7/en/show-collation.html
One comment mentioned also that if a database never exists an empty database had to be created first. This might be right in some cases but depends on the export file. If the exported file includes already the command to create the database then the database never has to be created in a separate step, which even could cause an error on import. So on import, it's advisable to have a look first in the file to know which commands are included there, on export, it's advisable to note the settings, especially if the file is very large and hard to read in an editor.
There are still more parameters for the command which are listed and explained here:
https://dev.mysql.com/doc/refman/5.7/en/mysql-command-options.html
If you use another database version consider searching for the corresponding version of the manual too. The mentioned links refer to MySQL version 5.7.
EDIT:
The same parameters are working for mysqldump too. So while the commands for export and import are different, the mentioned parameters are not.
Nevertheless there exists a special site in the manual that describes the options for mysqldump: https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html
To dump a database into an SQL file use the following command.
mysqldump -u username -p database_name > database_name.sql
To import an SQL file into a database (make sure you are in the same directory as the SQL file or supply the full path to the file), do:
mysql -u username -p database_name < database_name.sql
I think it's worth mentioning that you can also load a gzipped (compressed) file with zcat like shown below:
zcat database_file.sql.gz | mysql -u username -p -h localhost database_name
Go to the directory where you have the MySQL executable. -u for username and -p to prompt for the password:
C:\xampp\mysql\bin>mysql -u username -ppassword databasename < C:\file.sql
To import a single database, use the following command.
mysql -u username -p password dbname < dump.sql
To import multiple database dumps, use the following command.
mysql -u username -p password < dump.sql
To import a database, use the following command.
mysql> create new_database;
mysql> use new_database;
mysql> source (Here you need to import the path of the SQL file);
E.g.:
mysql> source E:/test/dump.sql;
You need to use forward slashes (/) even on Windows, e.g., E:/test/dump.sql instead of E:\test\dump.sql
Or double backslashes (\\) because of escaping, i.e., E:\\test\\dump.sql
mysql --user=[user] --password=[password] [database] < news_ml_all.sql
I kept running into the problem where the database wasn't created.
I fixed it like this:
mysql -u root -e "CREATE DATABASE db_name"
mysql db_name --force < import_script.sql
For exporting a database:
mysqldump -u username -p database_name > file.sql
For importing a database:
mysql -u username -p database_name < file.sql
For importing multiple SQL files at one time, use this:
# Unix-based solution
for i in *.sql ; do mysql -u root -pPassword DataBase < $i ; done
For simple importing:
# Unix-based solution
mysql -u root -pPassword DataBase < data.sql
For WAMP:
REM mysqlVersion - replace with your own version
C:\wamp\bin\mysql\mysqlVersion\bin\mysql.exe -u root -pPassword DataBase < data.sql
For XAMPP:
C:\xampp\mysql\bin\mysql -u root -pPassword DataBase < data.sql
You do not need to specify the name of the database on the command line if the .sql file contains CREATE DATABASE IF NOT EXISTS db_name and USE db_name statements.
Just make sure you are connecting with a user that has the permissions to create the database, if the database mentioned in the .sql file does not exist.
Import a database
Go to drive:
d:
MySQL login
c:\xampp\mysql\bin\mysql -u root -p
It will ask for pwd. Enter it:
pwd
Select the database
use DbName;
Provide the file name
\.DbName.sql
Use:
mysql -u root -p password -D database_name << import.sql
Use the MySQL help for details - mysql --help.
I think these will be useful options in our context:
[~]$ mysql --help
mysql Ver 14.14 Distrib 5.7.20, for osx10.12 (x86_64) using EditLine wrapper

What is fun, if we are importing a large database and not having a progress bar. Use Pipe Viewer and see the data transfer through the pipe
For Mac, brew install pv
For Debian/Ubuntu, apt-get install pv.
For others, refer to pv - Pipe Viewer

Go to the directory where you have MySQL.
c:\mysql\bin\> mysql -u username -p password database_name <
filename.sql
Also to dump all databases, use the -all-databases option, and no databases’ name needs to be specified anymore.
mysqldump -u username -ppassword –all-databases > dump.sql
Or you can use some GUI clients like SQLyog to do this.
You can try this query.
Export:
mysqldump -u username –-password=your_password database_name > file.sql
Import:
mysql -u username –-password=your_password database_name < file.sql
and detail following this link:
https://chartio.com/resources/tutorials/importing-from-and-exporting-to-files-using-the-mysql-command-line/
Add the --force option:
mysql -u username -p database_name --force < file.sql
The following command works for me from the command line (cmd) on
Windows 7 on WAMP.
d:/wamp/bin/mysql/mysql5.6.17/bin/mysql.exe -u root -p db_name < database.sql
Providing credentials on the command line is not a good idea. The above answers are great, but neglect to mention
mysql --defaults-extra-file=etc/myhost.cnf database_name < file.sql
Where etc/myhost.cnf is a file that contains host, user, password, and you avoid exposing the password on the command line. Here is a sample,
[client]
host=hostname.domainname
user=dbusername
password=dbpassword
Import into the database:
mysql -u username -p database_name < /file path/file_name.sql
Export from the database:
mysqldump -u username -p database_name > /file path/file_name.sql
After these commands, a prompt will ask for your MySQL password.
Similarly to vladkras's answer to How do import an SQL file using the command line in MySQL?.
Key differences for me:
The database has to exist first
No space between -p and the password
shell> mysql -u root -ppassword #note: no space between -p and password
mysql> CREATE DATABASE databasename;
mysql> using databasename;
mysql> source /path/to/backup.sql
I am running Fedora 26 with MariaDB.
I thought it could be useful for those who are using Mac OS X:
/Applications/xampp/xamppfiles/bin/mysql -u root -p database < database.sql
Replace xampp with mamp or other web servers.

How to use MySQL dump from a remote machine

How can I backup a mysql database which is running on a remote server, I need to store the back up file in the local pc.
Try it with Mysqldump
#mysqldump --host=the.remotedatabase.com -u yourusername -p yourdatabasename > /User/backups/adump.sql
Have you got access to SSH?
You can use this command in shell to backup an entire database:
mysqldump -u [username] -p[password] [databasename] > [filename.sql]
This is actually one command followed by the > operator, which says, "take the output of the previous command and store it in this file."
Note: The lack of a space between -p and the mysql password is not a typo. However, if you leave the -p flag present, but the actual password blank then you will be prompted for your password. Sometimes this is recommended to keep passwords out of your bash history.
No one mentions anything about the --single-transaction option. People should use it by default for InnoDB tables to ensure data consistency. In this case:
mysqldump --single-transaction -h [remoteserver.com] -u [username] -p [password] [yourdatabase] > [dump_file.sql]
This makes sure the dump is run in a single transaction that's isolated from the others, preventing backup of a partial transaction.
For instance, consider you have a game server where people can purchase gears with their account credits. There are essentially 2 operations against the database:
Deduct the amount from their credits
Add the gear to their arsenal
Now if the dump happens in between these operations, the next time you restore the backup would result in the user losing the purchased item, because the second operation isn't dumped in the SQL dump file.
While it's just an option, there are basically not much of a reason why you don't use this option with mysqldump.
This topic shows up on the first page of my google result, so here's a little useful tip for new comers.
You could also dump the sql and gzip it in one line:
mysqldump -u [username] -p[password] [database_name] | gzip > [filename.sql.gz]
mysqldump -h [domain name/ip] -u [username] -p[password] [databasename] > [filename.sql]
Tried all the combinations here, but this worked for me:
mysqldump -u root -p --default-character-set=utf8mb4 [DATABASE TO BE COPIED NAME] > [NEW DATABASE NAME]
If you haven't install mysql_client yet and using Docker container instead:
sudo docker exec MySQL_CONTAINER_NAME /usr/bin/mysqldump --host=192.168.1.1 -u username --password=password db_name > dump.sql
You can directly pipe it to the remote server where you wish to copy your data to:
mysqldump -u your_db_user_name -p --set-gtid-purged=OFF --triggers --routines --events --compress --skip-lock-tables --verbose your_local_sql_db_name | mysql -u your_db_user_name -p -h your_remote_server_ip your_remote_server_db_name
You need to have created the db on your remote sql server.
Using the above command, I was able to copy from my local sql server version 8.0.23 to my remote sqlserver running 8.0.25
This is how you would restore a backup after you successfully backup your .sql file
mysql -u [username] [databasename]
And choose your sql file with this command:
source MY-BACKED-UP-DATABASE-FILE.sql

How to export a mysql database using Command Prompt?

I have a database that is quite large so I want to export it using Command Prompt but I don't know how to.
I am using WAMP.
First check if your command line recognizes mysql command. If not go to command & type in:
set path=c:\wamp\bin\mysql\mysql5.1.36\bin
Then use this command to export your database:
mysqldump -u YourUser -p YourDatabaseName > wantedsqlfile.sql
You will then be prompted for the database password.
This exports the database to the path you are currently in, while executing this command
Note: Here are some detailed instructions regarding both import and export
Simply use the following command,
For Export:
mysqldump -u [user] -p [db_name] | gzip > [filename_to_compress.sql.gz]
For Import:
gunzip < [compressed_filename.sql.gz] | mysql -u [user] -p[password] [databasename]
Note: There is no space between the keyword '-p' and your password.
Well you can use below command,
mysqldump --databases --user=root --password your_db_name > export_into_db.sql
and the generated file will be available in the same directory where you had ran this command.
You could find more on the official reference for mysqldump: Import Export MySQL DB
Note: use --databases instead of --database since the last one is no more supported.
Enjoy :)
First of all
open command prompt then open bin directory in cmd (i hope you're aware with cmd commands)
go to bin directory of your MySql folder in WAMP program files.
run command
mysqldump -u db_username -p database_name > path_where_to_save_sql_file
press enter system will export particular database and create sql file to the given location.
i hope you got it :)
if you have any question please let me know.
Go to command prompt at this path,
C:\Program Files (x86)\MySQL\MySQL Server 5.0\bin>
Then give this command to export your database (no space after -p)
mysqldump -u[username] -p[userpassword] yourdatabase > [filepath]wantedsqlfile.sql
Locate your mysql instance with:
which mysql
If this is correct then export with the following (else navigate to the mysql instance in your mamp folder in bin):
mysqldump -u [username] -p [password] [dbname] > filename.sql
And if you wish to zip it at the sametime:
mysqldump -u [username] -p [password] [db] | gzip > filename.sql.gz
You can then move this file between servers with:
scp user#xxx.xxx.xxx.xxx:/path_to_your_dump/filename.sql.gz your_detination_path/
(where xxx.xxx.xxx.xxx is the server IP address)
And then import it with:
gunzip filename.sql.gz | mysql -u [user] -p [password] [database]
To export PROCEDUREs, FUNCTIONs & TRIGGERs too, add --routines parameter:
mysqldump -u YourUser -p YourDatabaseName --routines > wantedsqlfile.sql
The problem with all these solutions (using the > redirector character) is that you write your dump from stdout which may break the encoding of some characters of your database.
If you have a character encoding issue. Such as :
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ...
then, you MUST use -r option to write the file.
MySQL
mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump.sql
Using Docker
docker exec --rm -v $pwd:dump -it mysql:5:7 mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump/dump.sql
Note: this mounts the current path as dump inside the instance.
We found the answer here
Conversely, don't use < to import your dump into your database, again, your non-utf8 characters may not be passed; but prefer source option.
mysql -u user -pYourPasswordYouNowKnowHow --default-character-set=utf8 your-database
mysql> SET names 'utf8'
mysql> SOURCE dump.sql
Give this command to export your database, this will include date as well
mysqldump -u[username] -p[userpassword] --databases yourdatabase | gzip > /home/pi/database_backup/database_`date '+%m-%d-%Y'`.sql.gz
(no space after -p)
I have installed my wamp server in D: drive so u have to go to the following path from ur command line->(and if u have installed ur wamp in c: drive then just replace the d: wtih c: here)
D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button and select the currently working mysql version on your server if you have more than one mysql versions)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysqldump -u root -p password db_name > "d:\backupfile.sql"
here root is user of my phpmyadmin
password is the password for phpmyadmin so if u haven't set any password for root just nothing type at that place,
db_name is the database (for which database u r taking the backup)
,backupfile.sql is the file in which u want ur backup of ur database and u can also change the backup file location(d:\backupfile.sql) from to any other place on your computer
mysqldump -h [host] -p -u [user] [database name] > filename.sql
Example in localhost
mysqldump -h localhost -p -u root cookbook > cookbook.sql
mysqldump --no-tablespaces -u username -p pass database_name > db_backup_file.sql
Syntax
(mysqldump.exe full path) -u (user name) -p (password) (database name) > (export database file full path)
Example
c:>d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe -u root -p mydbname > d:\mydb.sql
where d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe will be your actual mysqldump.exe path, mydbname is the name of database which you want to export and d:\mydb.sql is the path where you want to store the exported database.
For import:
mysql -u db_username -p newFileName < databasName.sql
For export:
mysqldump -u db_username -p databasName > newFileName.sql
I have used wamp server. I tried on
c:\wamp\bin\mysql\mysql5.5.8\bin\mysqldump -uroot -p db_name > c:\somefolder\filename.sql
root is my username for mysql, and if you have any password specify it with:
-p[yourpassword]
Hope it works.
For windows OS :
When you get error 1064 mysql (42000) while trying to execute mysqldump command, exit from current terminal. And execute mysqldump command.
mysql>exit
c:\xampp\mysql\bin>mysqldump -uroot -p --databases [database_name] > name_for_export_db.sql
I was trying to take the dump of the db which was running on the docker and came up with the below command to achieve the same:
docker exec <container_id/name> /usr/bin/mysqldump -u <db_username> --password=<db_password> db_name > .sql
Hope this helps!
mysql -u -p databaseName>fileToPutDatabase
Login in your databse server and then hit the below command:-
mysql -u username -p databasename > exportfilename.sql
Then it will ask for password Enter the password and hit enter,it will take some time your database will be exported.
You can use this script to export or import any database from terminal
given at this link: https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh
echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo
mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql
if [ "$action" == "export" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
echo
else
echo -e "Using default location of mysqldump\n"
fi
read -p 'Give the name of database in which you would like to export: ' db_name
read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
$mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysql that you want to use: ' mysql_location
echo
else
echo -e "Using default location of mysql\n"
fi
read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
read -p 'Give the name of database in which to import this file: ' db_name
$mysql_location -u $u_name -p $db_name < $sql_file
else
echo "please select a valid command"
fi

How do I load a sql.gz file to my database? (importing)

is this right?
mysql -uroot -ppassword mydb < myfile.sql.gz
No, it isn't. The right way would be
zcat myfile.sql.gz | mysql -u root -ppassword mydb
Note there can be no space between the -p and password if using the -p syntax, refer http://dev.mysql.com/doc/refman/5.5/en/mysql-command-options.html#option_mysql_password
Use the following command:
gunzip < databasefile.sql.gz | mysql -u root -p dbname
You must not use the password directly in the terminal, use without it like follows
zcat YOUR_FILE.sql.gz | mysql -u YOUR_DB_USERNAME -p YOUR_DATABASE_NAME
Hit enter and when terminal asked for your password, type your password and hope everything will work fine.
Straight and clear:
gunzip -c myfile.sql.gz | mysql -uroot -ppassword mydb
-c option for gunzip writes to stdout, keeps original files
NOTE: You shouldn't put the password directly in the command. It's better to provide just -p and than enter the password interactively.
For Generating dbName.sql.gz
mysqldump -u <YOUR USERNAME> -p<YOUR PASSWORD> <YOUR DBNAME> | gzip > ~/mysqlBackup/dbName_`date +%Y%m%d%H%M`.sql.gz
For Loading dbName.sql.gz
zcat ~/mysqlBackup/<.SQL.GZ file> | mysql -u <YOUR USERNAME> -p<YOUR PASSWORD> <DATABASE NAME IN WHICH YOU WANT TO LOAD>
On windows you can do this:
First step! Install gzip for windows. I recommend using chocolatey to do it: (https://chocolatey.org/install)
choco install gzip -y
Now you can descompress your gz file and send it to mysql:
gzip -cd backup.sql.gz > mysql -uUSER -pPASSWORD -hLOCALHOST DATABASE
Good luck!
You have to follow below steps:
First check Mysql service should be running.
Then if you have compressed file, decompress it first.
Then you will find .sql file after decompressing.
Then find import data in left corner in Mysql.
Select option import from self-contained file and select
your .sql file and specify a new schema name.
Then click on import data.
After importing you will see your new schema in
available schema list.
