into How to import an SQL file using the command line in MySQL?
mariadb import sql (24)
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 ;
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?
A solution that worked for me is below:
Use your_database_name; SOURCE path_to_db_sql_file_on_your_local;
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
Sometimes the port defined as well as the server IP address of that database also matters...
mysql -u user -p user -h <Server IP> -P<port> (DBNAME) < DB.sql
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
Surley this works for other charsets too, how to show the right notation can be seen here:
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 separated 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 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:
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.
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
--triggers to keep the routines and triggers of original database. They are not copied by default.
Similarly to https://.com/a/17666285/1888983
Key differences for me:
- The database has to exist first
- No space between
-pand 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
Running fedora 26 with MariaDB.
mysql -u root -p password -D database_name << import.sql
Use mysql help for details
I think these will be useful options in our context

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
brew install pv
apt-get install pv.

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
To dump a database into a SQL file use the following command
mysqldump -u username -p database_name > database_name.sql
To import a 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)
mysql u -username -p database_name < database_name.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
#mysqlVersion replace with your own version C:\wamp\bin\mysql\mysqlVersion\bin\mysql.exe -u root -pPassword DataBase < data.sql
C:\xampp\mysql\bin\mysql -u root -pPassword DataBase < data.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
The following steps help to upload
file.sql to the MySQL database.
Step 1: Upload
file.sql.zip to any directory and unzip there
sudo apt-get install unzip
sudo apt-get unzip file.sql.zip
Step 2: Now navigate to that directory. Example:
mysql -u username -p database-name < file.sql
Enter the password and wait till uploading is completed.
Among all the answers, for the problem above, this is the best one:
mysql> use db_name; mysql> source file_name.sql;
mysql --user=[user] --password=[password] [database] < news_ml_all.sql
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
For information I just had default root + withoutpassword, it didn't works with all above answers.
I created a new user with all privileges and a password. It works.
-ppassword WITHOUT SPACE.
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
mamp or other web servers.
If you already have the database use the following to import the
dump or the
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
sql file exists, use the relative path in above.
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
- Open the MySQL command line
- Type the path of your mysql bin directory and press Enter
- Paste your SQL file inside the
binfolder of mysql server.
- Create a database in MySQL.
- Use that particular database where you want to import the SQL file.
source databasefilename.sqland Enter
- Your SQL file upload successfully.
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 backup purposes, make a BAT file and run this BAT file using Task Scheduler. It will take a backup of the database; just copy the following line and paste in Notepad and then save the .bat file, and run it on your system.
@echo off for /f "tokens=1" %%i in ('date /t') do set DATE_DOW=%%i for /f "tokens=2" %%i in ('date /t') do set DATE_DAY=%%i for /f %%i in ('echo %date_day:/=-%') do set DATE_DAY=%%i for /f %%i in ('time /t') do set DATE_TIME=%%i for /f %%i in ('echo %date_time::=-%') do set DATE_TIME=%%i "C:\Program Files\MySQL\mysql server 5.5\bin\mysqldump" -u username -ppassword mysql>C:/%DATE_DAY%_%DATE_TIME%_database.sql
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.
