DO

Execute expressions without returning a result set. This statement runs functions or expressions, often used for side effects like releasing locks.

Syntax

DO expr [, expr] ...

Description

DO executes the expressions but does not return any results. In most respects, DO is shorthand forSELECT expr, ..., but has the advantage that it is slightly faster when you do not care about the result.

DO is useful primarily with functions that have side effects, such as RELEASE_LOCK().
