How to quickly and completely empty a table in MySQL?

To quickly and completely empty a table, you can use the TRUNCATE TABLE statement.

The TRUNCATE TABLE statement can delete all the data in a table, and reset the auto-increment ID of the table (if applicable). Compared to the DELETE statement, the TRUNCATE TABLE statement executes faster because it directly removes the entire table instead of deleting data row by row.

Here is an example of using the TRUNCATE TABLE statement to empty a table:

TRUNCATE TABLE 表名;

Replace “table name” with the name of the table you want to clear.

It is important to note that the TRUNCATE TABLE statement will immediately delete all data in the table and cannot be undone. It is recommended to backup the data before executing the TRUNCATE TABLE statement if you need to save or temporarily store the data.
