A correlated select, update, and delete query is a type of SQL query that lets you delete all the rows from a table that are related to a specific row in another table.
This is how it works:
SELECT * FROM t1 WHERE id=2;
SELECT * FROM t2 WHERE id=1;
DELETE FROM t1 WHERE id=2;

A delete query was used to remove a record from the database. Nowadays, it is used to remove content from a website. Update queries can be used by developers to make changes to their application without having to write code for each change.
