DO

The DO statement executes an SQL expression without returning any result.

The syntax of the DO statement is as follows:

DO expr [, expr ...]

In some scenarios, the DO statement is equivalent to SELECT expr for a quick response without returning results. Here is an example:

SELECT SLEEP(5);
+----------+
| SLEEP(5) |
+----------+
|        0 |
+----------+
1 row in set (5.001 sec)

DO SLEEP(5);
Query OK, 0 rows affected (5.011 sec)
