Import SQL file by command line in Windows 7

问题:

I want to import an SQL file (size > 500MB) into a database. I have wamp on my PC. Phpmyadmin does not work well with this size. I changed all parameters in php.ini (max_upload_size etc.). But it does not work for me. So I want to import it by command line.

I used these commands for import the file:

mysql -u root -p sysdat < D:\Nisarg\ISPC\Database\sysdat.sql 
mysql -u root -p -D sysdat < D:\Nisarg\ISPC\Database\sysdat.sql
mysql -u root sysdat < D:\Nisarg\ISPC\Database\sysdat.sql -p 

These all are not working.

回答1:

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

回答2:

If you have wamp installed then go to command prompt , go to the path where mysql.exe exists , like for me it was : C:\wamp\bin\mysql\mysql5.0.51b\bin , then paste the sql file in the same location and then run this command in cmd :

C:\wamp\bin\mysql\mysql5.0.51b\bin>mysql -u root -p YourDatabaseName < YourFileName.sql

回答3:

To import database from dump file use:

mysql -u UserName -p Password DatabaseName < FileName.sql 

In wamp

C:\wamp\bin\mysql\mysql5.0.51b\bin>mysql mysql -uroot -p DatabaseName < FileName.sql

----------------WARM server.

step 1: go to cmd go to directory C:\wamp\bin\mysql\mysql5.6.17 hold Shift + right click (choose "open command window here")

step 2: C:\wamp\bin\mysql\mysql5.6.17\bin>mysql -u root -p SellProduct < D:\file.sql

in this case
+ Root is username database  
+ SellProduct is name database.
+ D:\file.sql is file you want to import

---------------It's work with me -------------------

回答5:

To import database from dump file (in this case called filename.sql)

    use: mysql -u username -p password database_name < filename.sql 

you are on Windows you will need to open CMD and go to directory where mysql.exe is installed. you are using WAMP server then this is usually located in: C:\wamp\bin\mysql\mysql5.5.8\bin (*note the version of mysql might be different)

So you will: cd C:\wamp\bin\mysql\mysql5.5.8\bin

and then execute one of the above commands. Final command like this

    C:\wamp\bin\mysql\mysql5.5.8\bin>mysql -u rootss -p pwdroot testdatabasename < D:\test\Projects\test_demo_db.sql

回答6:

TRY THIS

  C:\xampp\mysql\bin\mysql -u {username} -p {databasename} < {filepath}

if username=root ,filepath='C:/test.sql', databasename='test' ,password ='' then command will be

  C:\xampp\mysql\bin\mysql -u root  test < C:/test.sql

回答7:

I use mysql -u root -ppassword databasename < filename.sql in batch process. For an individual file, I like to use source more because it shows the progress and any errors like

Query OK, 6717 rows affected (0.18 sec)
Records: 6717  Duplicates: 0  Warnings: 0

1. Log in to MySQL using mysql -u root -ppassword

2. In MySQL, change the database you want to import in: mysql>use databasename;

   • This is very important otherwise it will import to the default database

3. Import the SQL file using source command: mysql>source path\to\the\file\filename.sql;

回答8:

Related to importing, if you are having issues importing a file with bulk inserts and you're getting MYSQL GONE AWAY, lost connection or similar error, open your my.cnf / my.ini and temporarily set your max_allowed_packet to something large like 400M

Remember to set it back again after your import!

回答9:

Try this it will work. Do not enter password it will ask one you execute the following cmd

C:\xampp\mysql\bin\mysql -u xxxxx -p -h localhost your_database_name < c:\yourfile.sql

回答10:

mysql : < (for import) > (for export)

in windows, you want to take backup or import the sql file, then goto cmd prompt type the address were the mysql is installed eg:C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin> after this

C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin> mysql -u UserName -p Password DatabaseName < FileName.sql (import)

C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin> mysql -u UserName -p Password DatabaseName > FileName.sql (export)

回答11:

If those commands don't seems to work -- I assure you they do --, check the top of your sql dump file for the use of :

CREATE DATABASE {mydbname}

and

USE {mydbname}

The last parameter {mydbname} of the mysql command can be misleading : if CREATE DATABASE an USE are in your dump file, the import will in fact be done in this database, not in the one in the mysql command.

The mysqldump command that will prompt CREATE DATABASE and USE is :

mysqldump.exe -h localhost -u root --databases xxx > xxx.sql

Use mysqldump without --databases to leave out CREATE DATABASE and USE :

mysqldump.exe -h localhost -u root xxx > xxx.sql

回答12:

If you are using Windows PowerShell you may get the error:

The '<' operator is reserved for future use.

In that case just type the command:

cmd

To switch to the cmd shell and then retype the command and it will work.

c:\xampp\mysql\bin\mysql -u root -p my_database < my_database_dump.sql

To get back to PowerShell type:

exit

回答13:

If you don't have password you can use the command without

-u

Like this

C:\wamp>bin\mysql\mysql5.7.11\bin\mysql.exe -u {User Name} {Database Name} < C:\File.sql

Or on the SQL console

mysql -u {User Name} -p {Database Name} < C:/File.sql

回答14:

First open Your cmd pannel And enter mysql -u root -p (And Hit Enter) After cmd ask's for mysql password (if you have mysql password so enter now and hit enter again) now type source mysqldata.sql(Hit Enter) Your database will import without any error

回答15:

If you are running WampServer on your local machine, import means restoring the dump file that you have (in sql format)

Here are the steps

1. Go to command line by going to Start -> Run and typing in cmd.

2. Change the directory to Mysql bin directory. It will be like

   c:\wamp\bin\mysql\mysql5.7.14\bin

3. It would be better to keep the dump file in the above directory( we can delete, after restoration)

4. Hope you have created the database (either through phpMyadmin or using command line)

5. Then type the command mysql.exe -u root -p databasename < filename.sql

Please note the difference, it is 'mysql.exe' not 'mysql'

To import SQL file what works for me

For Wamp-Server

1. Find mysql in wamp. In my computer it's location is "C:\wamp64\bin\mysql\mysql5.7.21\bin"

Open cmd and once you get inside bin you have to write " mysql -uroot -p database_name < filename.sql"

remember to put sql file under bin.

in nutshell you have to do this:-

C:\wamp64\bin\mysql\mysql5.7.21\bin>mysql -uroot -p database_name < filename.sql

After this, it will ask for the password, mine password was nothing(BLANK).

hope it helps someone.
