How to import sql files into mysql

Sql file refers to a text file that saves a series of SQL statements, generally with the extension ".sql". In MySQL, we can use the "mysql" command line tool or client software to import SQL files and complete the creation of database tables and data. This article will introduce the import operation of SQL files in MySQL.

1. Use the command line to import SQL files

1. Open the command prompt or terminal window, use the cd command to enter the mysql/bin directory (under Windows systems, the mysql/bin directory is generally In the mysql installation path under the drive letter where mysql is located; under Linux/macOS systems, the mysql/bin directory is generally under /usr/local/mysql/bin or /opt/mysql/bin).

2. Enter the following command to log in to the MySQL server (you need to create a user and password in MySQL in advance):

   mysql -u username -p

   Copy after login

   Among them, "username" represents the login user name. The "-p" parameter indicates that a password is required.

3. Create a new database (if it already exists, ignore this step):

   CREATE DATABASE databasename;

   Copy after login

   Note: databasename needs to be replaced with the actual database name.

4. Execute the SQL file and import the database table and data:

   USE databasename;
   SOURCE /path/to/sqlfile.sql;

   Copy after login

   Among them, /path/to/sqlfile.sql needs to be replaced with the path where the actual SQL file is located.

5. After the execution is completed, enter the following command in the MySQL client to view the imported database tables and data:

   SHOW TABLES;

   Copy after login

   Copy after login

2. Use the client Import the SQL file into the client software

1. Open the MySQL client software (such as MySQL Workbench, Navicat, etc.).
2. Connect to the MySQL server (you need to know the IP address, port number, user name, password and other information of the MySQL server in advance).
3. Open the "Import" function, select the SQL file to be imported and specify the database.
4. Set some options (such as whether to ignore error messages), and then click "Start Import".

5. After the import is completed, enter the following command in the MySQL client to view the imported database tables and data:

   SHOW TABLES;

   Copy after login

   Copy after login

Summary:

Whether you are using the command line or client software, importing SQL files into MySQL requires logging in to the MySQL server first, and creating a new database before importing data (if it already exists, you need to ignore this step). When the SQL file is large, it may be more convenient and easier to manage using client software to import. No matter which method is used, using imported SQL files can quickly create database tables and data, providing more efficient services for data analysis and development.
