MySQL Shell is an interactive command-line tool for managing and interacting with MySQL databases. It offers a modern and user-friendly interface for executing SQL statements, managing schemas, and performing administrative tasks. It also provides advanced features like scripting and debugging capabilities.

MySQL Shell can be installed on various platforms, including Windows, Linux, and macOS. You can download the latest version from the official MySQL website.

Do You Know?

MySQL Shell is available as part of the MySQL Workbench installation package.

To connect to a MySQL server using MySQL Shell, you can use the following command:

mysql --host=localhost --user=root --password

Replace localhost, root, and password with your actual server details.

Here are some basic commands that you can use in MySQL Shell:

  • use database_name;: Switch to a specific database.
  • show databases;: List available databases.
  • show tables;: List tables in the current database.
  • select * from table_name;: Retrieve all data from a table.
  • insert into table_name (column1, column2) values (value1, value2);: Insert data into a table.
  • update table_name set column1 = value1 where condition;: Update data in a table.
  • delete from table_name where condition;: Delete data from a table.
Important Note

For more details on specific commands and syntax, refer to the official MySQL documentation.

MySQL Shell offers advanced features that enhance your database management capabilities. Some key features include:

  • Scripting: Create and execute complex SQL scripts.
  • Debugging: Use the debug command to step through your scripts and inspect variables.
  • Data Manipulation Language (DML): Perform various data operations efficiently.
  • Data Definition Language (DDL): Define and modify database schemas.

MySQL Shell allows you to write scripts that automate database tasks. You can create scripts using a text editor and execute them using the source command. For example:

-- Create a new database
  CREATE DATABASE my_new_db;
  
  -- Use the new database
  USE my_new_db;
  
  -- Create a table
  CREATE TABLE my_table (
  id INT PRIMARY KEY,
  name VARCHAR(255)
  );

Save this script as create_db.sql and execute it with the following command:

mysql --host=localhost --user=root --password --source=create_db.sql

If you encounter any errors while using MySQL Shell, you can consult the official documentation or search for solutions online. Common troubleshooting tips include:

  • Verify your connection details.
  • Check for syntax errors in your SQL statements.
  • Ensure that you have the necessary permissions.
  • Use the help command to get information about specific commands.
