MySQL - Rename, Truncate and DROP Statements

27.5k

Unlike TRUNCATE, which just deletes the data from the tables, the DROP command deletes both the data and the table's complete schema/structure from the database.

To remove a table definition and its contents, use the DROP command. The TRUNCATE command, on the other hand, is used to delete all of the rows from a table.

Dropping a database removes the database from a SQL Server instance as well as the actual disc files it uses. The disc files are not erased if the database or any of its files is offline when it is dropped. Using Windows Explorer, you can manually delete these files.

To remove a table definition and its contents, use the DROP command. The TRUNCATE command, on the other hand, is used to delete all of the rows from the table.

TRUNCATE TABLE entirely depletes a table. It necessitates the DROP permission. TRUNCATE TABLE is equivalent to a DELETE statement that deletes all rows or a series of DROP TABLE and CREATE TABLE commands in terms of logic. TRUNCATE TABLE skips the DML method of eliminating data in order to achieve high efficiency.
