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
to keep the routines and triggers of 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 don'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
cmd.exe /c "mysql -u root -p db_name < backup-file.sql"
MySQL command line
mysql> use db_name;
mysql> source backup-file.sql;
<
operator in mysql? (ubuntu18/20)
-u
and -p
while the Unix example does not. The interface for mysql
is the same on both, so most likely you need the same command in Unix as is presented here for Windows.
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 ;
autocommit=0
portion made a world of difference in terms of the speed.
autocommit=0
will work on larger files? like 8gb sql file.
autocommit
. It's worth checking the database dump in an editor, it might already begin with SET autocommit=0;
.
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
-p
and password
mysql -u root -p"password" bank < bank.sql
mysql -u username -ppassword db_name < file.sql
.bash_history
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;
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
gzcat
instead of zcat
.
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
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 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
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 < $i ; done
For simple importing:
# Unix-based solution
mysql -u root -pPassword DataBase < data.sql
For WAMP:
REM mysqlVersion - replace with your own version
C:\wamp\bin\mysql\mysqlVersion\bin\mysql.exe -u root -pPassword DataBase < data.sql
For XAMPP:
C:\xampp\mysql\bin\mysql -u root -pPassword DataBase < data.sql
You do not need to specify the name of the database on the command line if the .sql file contains CREATE DATABASE IF NOT EXISTS db_name
and USE db_name
statements.
Just make sure you are connecting with a user that has the permissions to create the database, if the database mentioned in the .sql file does not exist.
I kept running into the problem where the database wasn't created.
I fixed it like this:
mysql -u root -e "CREATE DATABASE db_name"
mysql db_name --force < import_script.sql
Import a database
Go to drive: d: MySQL login c:\xampp\mysql\bin\mysql -u root -p It will ask for pwd. Enter it: pwd Select the database use DbName; Provide the file name \.DbName.sql
D:
? Is file DbName.sql
presumed to be at the root of drive D:
? Can you elaborate? Please respond by editing (changing) your answer, not here in comments (without "Edit:", "Update:", or similar - the question/answer should appear as if it was written today).
Use:
mysql -u root -p password -D database_name << import.sql
Use the MySQL help for details - mysql --help
.
I think these will be useful options in our context:
[~]$ mysql --help

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

Try this code.
mysql -u username -p database_name < file.sql
For more information: How to import an SQL file using the command line in MySQL
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:
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.
Success story sharing
sudo mysql -u username -p database_name < file.sql
works in some cases.-R
and--triggers
seem to be options formysqldump
, which wasn't immediately clear to me, based on the answer. Additionally,--triggers
is enabled by default "This option is enabled by default; disable it with--skip-triggers
."
