I want to dump my DB with a click on a button in my C#.Net App.
I thought about using
Process.Start(#"mysqldump", #"-u root -p mydb > dump.sql");
but this command opens a command prompt asking for the MySQL user password.
how can I avoid this?
Instead of this command :
mysql -u root -p mydb > dump.sql
Try using this, passing the password in the command, so mysqldump doesn't ask for it :
mysqldump -u root --password=YOUR_PASSWORD mydb > dump.sql

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

else
echo "please select a valid command"

Does anybody know how to export database?
I'm using TeraTerm and i want to export the database for backup purpose. I tried searching on google about the command but i can't find it.
EDIT:
Thank you for your time and effort in answering my question.The database was already exported. I use this :
mysqldump -u root -ptest test_db > backup.sql
You can use the mysqldump command this way:
mysqldump -u root -ptest test_db > backup.sql
Where username is root, root password is test and database name is test_db
If you are using mysql database, then there are numerous ways you can do that.
One is that you can set up 'phpmyadmin' on your server and export the database using the phpmyadmin web interface.
Or you can use this command:
"mysqldump -u [user] -p[password] [database-name]" > [database-export-file-name.sql]
Note that there is no space between -p and password.
See this for reference: http://www.itworld.com/article/2833078/it-management/3-ways-to-import-and-export-a-mysql-database.html
Is there SQL command where you can do MySQL dump inside the MySQL console?
I tried mysqldump but it does not work...
I'm trying to output into SQL file.
You cannot run mysqldump within a MySQL console since mysqldump is an external command like the mysql console.
Exit the console and use the mysqldump command as follows:
mysqldump -u username -p -h hostname (or ip address) databasename > sqlfilename
It will ask for password.
More details of mysqldump can be found at http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
use \!:
\! mysqldump -u username -p database > database_dump.sql
MySQL Documentation Reference (see System command)
use:
mysqldump -u username -p database
database: name of database
username: dbuser

mysql gives me the syntax error with the following line... i dont know what is wrong with this...
mysqldump -u root -p root mydatabase > dumpfile.sql
i am using windows vista...
plz help here..
thnx..
Make sure that you are running this from the normal command line and not within the mysql command line. So like this:
C:\[path to mysqldump app] > mysqldump -u root -p root mydatabase > dumpfile.sql
not
mysql > mysqldump -u root -p root mydatabase > dumpfile.sql
The -p part is the problem. From the manual:
The password to use when connecting to the server. If you use the
short option form (-p), you cannot have a space between the option
and the password. If you omit the password value following the
--password or -p option on the command line, you are prompted for
one.
Try
mysqldump -u root -proot mydatabase > dumpfile.sql
But in the future, please ask a proper question including any error messages you get (you certainly got one in this case) so people don't have to guess.
