MySQL 9.2 Reference Manual  /  ...  /  DEALLOCATE PREPARE Statement

15.5.3 DEALLOCATE PREPARE Statement

Press CTRL+C to copy
{DEALLOCATE | DROP} PREPARE stmt_name

To deallocate a prepared statement produced with PREPARE, use a DEALLOCATE PREPARE statement that refers to the prepared statement name. Attempting to execute a prepared statement after deallocating it results in an error. If too many prepared statements are created and not deallocated by either the DEALLOCATE PREPARE statement or the end of the session, you might encounter the upper limit enforced by the max_prepared_stmt_count system variable.

For examples, see Section 15.5, “Prepared Statements”.
