DROP PROCEDURE IF EXISTS procedure_name;
Where, procedure_name is the name of the stored procedure to be deleted.

2. Use MySQL Workbench to delete stored procedures: MySQL Workbench is a graphical database management tool that provides a simple way to manage and operate MySQL databases. If you use MySQL Workbench, you can delete stored procedures by following these steps:
- Open MySQL Workbench and connect to your MySQL database.
- Select the "SCHEMAS" tab in the navigation bar and expand the database to display the stored procedures.
- Find the stored procedure you want to delete, right-click on it and select the "Delete" option.

3. Use command line tools to delete stored procedures: In addition to MySQL client and MySQL Workbench, you can also use command line tools to delete stored procedures. The following are some commonly used command line tools:
- Using the mysql command line tool: You can open a command prompt or terminal window and execute the following command to delete the stored procedure:
mysql -u username -p -e "DROP PROCEDURE IF EXISTS procedure_name" database_name
Among them, username is your MySQL username, procedure_name is the name of the stored procedure to be deleted, and database_name is the name of the database where the stored procedure resides.
- Use the mysqldump command line tool: You can use the mysqldump command line tool to export a database containing stored procedures and delete the definition of the stored procedures in the export file. You can then re-import the export file into the MySQL database to delete the stored procedure. This method requires some extra steps and actions, but effectively removes the stored procedure.
No matter which method you use, make sure you have sufficient permissions before deleting the stored procedure, and operate with caution to avoid deleting the wrong stored procedure or causing data loss. If you are not sure how to delete a stored procedure, it is recommended to refer to MySQL's official documentation or seek help from a professional database administrator.
