how to import the database to mysql under linux? - mysql

The sql file named:bag.sql in /var/www/html/web(/var/www/html/web/bag.sql)
the current directory is [localhost web]i used mysql -uusername -p databasename > bag.sql
then let me input the password. i wait for long time, it doesn't show ok. why? how to import the database to mysql under centos.

if you have already created database then use below steps to import data from .sql file
tell which database to use:
use databasename;
Now give the source file path
source /var/www/html/web/bag.sql;

You need mysql -uusername -p databasename < bag.sql.
< Means "get the program's input from this file"
> Means "write the program's output to this file"

Connect to mysql database server
$ mysql -uusername -ppassword
Check database exists are not
$ show databases;
If not create the same
mysql>create database mydb;
note: mydb is database name(Give your own).
Check again for the database follow step 2.
exit
Import data to mydb(your own) database
$ mysql -uusername -ppassword mydb < bag.sql
note: your bag.sql is in the current directory from where you are executing the above command
Check for imported data.
YES FOR LONG WAIT YOU NEED TO CHECK YOUR BAG.SQL FILE SIZE.
Symbol '$' is shell prompt

Let me offer up another alternative using pv
pv /path/to/file.sql | mysql -uUSERNAME -pPASSWORD -D DATABASE_NAME
This will show you a progress indicator for the import. If you have never used pv it is a piper viewer tool in linux.

you're using the wrong redirection operator. > is used for sending the output to a file, not taking input from a file. Use <.

mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
source

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
pv import.sql | mysql -u root -p password -D database_name

1.47GiB 1:53:00 [ 385KiB/s] [=============> ] 14% ETA 11:05:36
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.

Restoring a MySQL table back to the database

I have a trouble in restoring MySQL table back to the database from command line. Taking backup of a table is working with mysqldump.Taking backup and restoring of a database is also working properly. I have used:
mysql -uroot -p DatabaseName TableName < path\TableName.sql
Thanks in advance
Ah, I think I see the problem here.
Your backup script looks fine. tbl_name works correctly as the optional 2nd argument.
To restore, you should simply run
mysql -uroot -p DatabaseName < path\TableName.sql
Running man mysql would have shown you the correct arguments and options
mysql [options] db_name
As your backup script only contains one table, only that table will be restored into your database.
Taking backup
mysqldump -u -p mydatabase table1 > database_dump.sql
restoring from backup flie need not include table name
mysql -u -p mydatabase < database_dump.sql
Best way to restore your database:
open cmd at bin folder
login to mysql:
mysql -uroot -pyour_password
show databases;
use db_name;
now hit source and put the complete path from address bar where your sql file is stored and hit ;
for example :
source db_name.sql;
Copy your db.sql file to your Mysql Server if you are in a remote machine:
$rsync -Cravzp --progress db.sql user#192.168.10.1:/home/user
Now you can go to your remote server as:
$ssh -l user 192.168.10.1
In the Mysql Server you must to do this:
user#machine:~$mysql -h localhost -u root -p
Obs: The file db.sql must be in the same place (/home/user).
Now type this command in you Mysql Server:
mysql>'\'. db.sql + Enter. Obs: Remove all ' from this command to work

How to convert .sql file to tables in mysql db

I have .sql files that I'm guessing is auto-generated. I did not generate this file, but anyway it includes the database name and all tables with fields. I'd like to add the db and tables to my mysql localhost and would like to know how to do this. I have tried uploading the file but keep getting errors about my sql syntax. The syntax looks all correct to me so perhaps the .sql file needs to be changed?
From command-line:
mysql -u root -p databaseName < file.sql
Where databaseName is an already created empty database and file.sql is the .sql file you have, you must be in the same folder as the file when you run the command. This also assumes using root as the user and that it is password protected. Modify as needed for your own setup.
Additionally, you can do the reverse by flipping the angled bracket to create a database dump to a file. Like below.
mysql -u root -p databaseName > file.sql
To IMPORT:
ype the following command to import sql data file:
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
In this example, import 'data.sql' file into 'blog' database using vivek as username:
$ mysql -u sat -p -h localhost blog < data.sql
If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
OR use hostname such as mysql.cyberciti.biz
$ mysql -u username -p -h mysql.cyberciti.biz database-name < data.sql
If you do not know the database name or database name is included in sql dump you can try out something as follows:
$ mysql -u username -p -h 202.54.1.10 < data.sql
Refer: http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html
If you want a GUI tool then you could probably use SQLyog or navicat for this.
You also can use a GUI tool - dbForge Studio for MySQL to execute the script. The SQL syntax check option will highlight syntax errors automatically, on file opening.

How to import an SQL file by using mysqldump on Windows through command line

How do I import an SQL file to MySQL dump using command line. I am using windows.
Navigate to the directory where you have mysql and issue this command, changing the bold values to your file/database locations.
c:\mysql\bin\> mysql -u USERNAME -p PASSWORD database_name < filename.sql
Simple steps to import sql file.
Click on WampServer and then go to MySQL=> MySQL console
enter password \If no password click simply enter
create database database_name; \If database already there skip this step
use database_name;
source D:\backup.sql \Path of database file
To dump all databases, use the -all-databases option. With that option, no database needs to be specified.
mysqldump -u username -ppassword –all-databases > dump.sql
Try like this:
I think you need to use the full path at the command line, something like this, perhaps:
C:\xampp\mysql\bin\mysql -u {username} -p {databasename} < file_name.sql
Refer this link also:
http://www.ryantetek.com/2011/09/importing-large-sql-files-through-command-line-when-using-phpmyadminxampp/
Try this
C:\Program Files\Mysql\Mysql server 5.6\bin\mysql -u {username} -p {password} {your database name} < file-name.sql
Note here file-name.sql is in mysql server 5.6\bin

How can I import a database with MySQL from terminal?

How can I import a database with mysql from terminal?
I cannot find the exact syntax.
Assuming you're on a Linux or Windows console:
Prompt for password:
mysql -u <username> -p <databasename> < <filename.sql>
Enter password directly (not secure):
mysql -u <username> -p<PlainPassword> <databasename> < <filename.sql>
Example:
mysql -u root -p wp_users < wp_users.sql
mysql -u root -pPassword123 wp_users < wp_users.sql
See also:
4.5.1.5. Executing SQL Statements from a Text File
Note: If you are on windows then you will have to cd (change directory) to your MySQL/bin directory inside the CMD before executing the command.
Preferable way for windows:
Open the console and start the interactive MySQL mode
use <name_of_your_database>;
source <path_of_your_.sql>
mysql -u <USERNAME> -p <DB NAME> < <dump file path>
-u - for Username
-p - to prompt the Password
Eg. mysql -u root -p mydb < /home/db_backup.sql
You can also provide password preceded by -p but for the security reasons it is not suggestible. The password will appear on the command itself rather masked.
Directly from var/www/html
mysql -u username -p database_name < /path/to/file.sql
From within mysql:
mysql> use db_name;
mysql> source backup-file.sql
Open Terminal Then
mysql -u root -p
eg:- mysql -u shabeer -p
After That Create a Database
mysql> create database "Name";
eg:- create database INVESTOR;
Then Select That New Database "INVESTOR"
mysql> USE INVESTOR;
Select the path of sql file from machine
mysql> source /home/shabeer/Desktop/new_file.sql;
Then press enter and wait for some times if it's all executed then
mysql> exit
From Terminal:
mysql -uroot -p --default-character-set=utf8 database_name </database_path/database.sql
in the terminal type
mysql -uroot -p1234; use databasename; source /path/filename.sql
Below command is working on ubuntu 16.04, I am not sure it is working or not other Linux platforms.
Export SQL file:
$ mysqldump -u [user_name] -p [database_name] > [database_name.sql]
Example : mysqldump -u root -p max_development > max_development.sql
Import SQL file:
$ mysqldump -u [user_name] -p [database_name] < [file_name.sql]
Example: mysqldump -u root -p max_production < max_development.sql
Note SQL file should exist same directory
I usually use this command to load my SQL data when divided in files with names : 000-tableA.sql, 001-tableB.sql, 002-tableC.sql.
for anyvar in *.sql; do <path to your bin>/mysql -u<username> -p<password> <database name> < $anyvar; done
Works well on OSX shell.
Explanation:
First create a database or use an existing database. In my case, I am using an existing database
Load the database by giving <name of database> = ClassicModels in my case and using the operator < give the path to the database = sakila-data.sql
By running show tables, I get the list of tables as you can see.
Note : In my case I got an error 1062, because I am trying to load the same thing again.
mysql -u username -ppassword dbname < /path/file-name.sql
example
mysql -u root -proot product < /home/myPC/Downloads/tbl_product.sql
Use this from terminal
After struggling for sometime I found the information in https://tommcfarlin.com/importing-a-large-database/
Connect to Mysql (let's use root for both username and password):
mysql -uroot -proot
Connect to the database (let's say it is called emptyDatabase (your should get a confirmation message):
connect emptyDatabase
3 Import the source code, lets say the file is called mySource.sql and it is in a folder called mySoureDb under the profile of a user called myUser:
source /Users/myUser/mySourceDB/mySource.sql
Open the MySQL Command Line Client and type in your password
Change to the database you want to use for importing the .sql file data into. Do this by typing:
USE your_database_name
Now locate the .sql file you want to execute.
If the file is located in the main local C: drive directory and the .sql script file name is currentSqlTable.sql, you would type the following:
\. C:\currentSqlTable.sql
and press Enter to execute the SQL script file.
If you are using sakila-db from mysql website,
It's very easy on the Linux platform just follow the below-mentioned steps, After downloading the zip file of sakila-db, extract it. Now you will have two files, one is sakila-schema.sql and the other one is sakila-data.sql.
Open terminal
Enter command mysql -u root -p < sakila-schema.sql
Enter command mysql -u root -p < sakila-data.sql
Now enter command mysql -u root -p and enter your password, now you have entered into mysql system with default database.
To use sakila database, use this command use sakila;
To see tables in sakila-db, use show tables command
Please take care that extracted files are present in home directory.
First connect to mysql via command line
mysql -u root -p
Enter MySQL PW
Select target DB name
use <db_name>
Select your db file for import
SET autocommit=0; source /root/<db_file>;
commit;
This should do it. (thanks for clearing)
This will work even 10GB DB can be imported successfully this way. :)
In Ubuntu, from MySQL monitor, you have already used this syntax:
mysql> use <dbname>
-> The USE statement tells MySQL to use dbname as the default database for subsequent statements
mysql> source <file-path>
for example:
mysql> use phonebook;
mysql> source /tmp/phonebook.sql;
Important: make sure the sql file is in a directory that mysql can access to like /tmp
If you want to import a database from a SQL dump which might have "use" statements in it, I recommend to use the "-o" option as a safeguard to not accidentially import to a wrong database.
• --one-database, -o
Ignore statements except those those that occur while the default
database is the one named on the command line. This filtering is
limited, and based only on USE statements. This is useful for
skipping updates to other databases in the binary log.
Full command:
mysql -u <username> -p -o <databasename> < <filename.sql>
For Ubuntu/Linux users,
Extract the SQL file and paste it somewhere
e.g you pasted on desktop
open the terminal
go to your database and create a database name
Create database db_name;
Exit Mysql from your terminal
cd DESKTOP
mysql -u root -p db_name < /cd/to/mysql.sql
Enter the password:....
Before running the commands on the terminal you have to make sure that you have MySQL installed on your terminal.
You can use the following command to install it:
sudo apt-get update
sudo apt-get install mysql-server
Refrence here.
After that you can use the following commands to import a database:
mysql -u <username> -p <databasename> < <filename.sql>
The simplest way to import a database in your MYSQL from the terminal is done by the below-mentioned process -
mysql -u root -p root database_name < path to your .sql file
What I'm doing above is:
Entering to mysql with my username and password (here it is root & root)
After entering the password I'm giving the name of database where I want to import my .sql file. Please make sure the database already exists in your MYSQL
The database name is followed by < and then path to your .sql file. For example, if my file is stored in Desktop, the path will be /home/Desktop/db.sql
That's it. Once you've done all this, press enter and wait for your .sql file to get uploaded to the respective database
There has to be no space between -p and password
mysql -u [dbusername] -p[dbpassword] [databasename] < /home/serverusername/public_html/restore_db/database_file.sql
I always use it, it works perfectly. Thanks to ask this question. Have a great day. Njoy :)
