How to use the truncate statement in a database?

The TRUNCATE statement is used to delete all data in a database while keeping the table structure.

The general syntax for using the TRUNCATE statement is as follows:

Clear all data in the table called table_name;

Here, table_name is the name of the table from which data is to be deleted.

Important points to note:

1. The TRUNCATE statement is a DDL (Data Definition Language) command, so it automatically commits the transaction when executed.
2. The TRUNCATE statement does not activate triggers on a table.
3. The TRUNCATE statement is unable to recover deleted data.
4. The TRUNCATE statement can be used within a transaction, but it cannot be mixed with other DML (Data Manipulation Language) statements such as SELECT, INSERT, UPDATE, DELETE.

Please be aware that before using the TRUNCATE statement, it is important to back up the data that needs to be deleted to prevent any accidental operations from causing data loss.
