How to bulk delete data in MySQL?

To delete data in bulk, you can use the DELETE statement in MySQL combined with the WHERE clause. Here is an example:

Suppose we have a table named users with many rows of data, and we want to delete in bulk the data of users over the age of 30. This can be achieved by using the following SQL statement:

DELETE FROM users WHERE age > 30;

This statement will delete all rows in the users table where the age is greater than 30 years old.

Please be cautious when performing batch deletion operations, make sure you really want to delete this data. Before executing the delete operation, it is recommended to back up or use a SELECT statement to query the data to be deleted to avoid accidentally deleting important data.
