Can you explain what the DELETE operator does in SQL and in what cases it is used?

The DELETE operator in SQL is used to delete records from a table. It deletes all rows that match the condition in the WHERE clause. If no condition is specified, all records in the table are deleted.

Example:

DELETE FROM Users WHERE IsActive = 0;

This query deletes all users where the IsActive field equals 0. DELETE is used when you need to clear or remove outdated data from the database.
