MySQL Drop Table

This lesson is part of Node.js · All levels

Summary

DROP TABLE permanently deletes a table with all its structure and data, thus differing from DELETE which only deletes rows. This order is destructive and cannot be revoked without backup. Therefore, run only after you have verified the need and have backed up the data.

Key points

DROP TABLE permanently removes the table and its structure and contents
DROP TABLE IF NOT EXIST to avoid errors when the table does not exist
TRUNCATE deleted all the lines but the table structure remains
Always backup before executing a destructive order in production
