DEALLOCATE / DROP PREPARE
Syntax
{DEALLOCATE | DROP} PREPARE stmt_name
Description
To deallocate a prepared statement produced with PREPARE, use a
DEALLOCATE PREPARE statement that refers to the prepared statement
name.
A prepared statement is implicitly deallocated when a new PREPARE command is issued. In that case, there is no need to use DEALLOCATE.
Attempting to execute a prepared statement after deallocating it results in an error, as if it was not prepared at all:
ERROR 1243 (HY000): Unknown prepared statement handler (stmt_name) given to EXECUTE
If the specified statement has not been PREPAREd, an error similar to the following will be produced:
ERROR 1243 (HY000): Unknown prepared statement handler (stmt_name) given to DEALLOCATE PREPARE
Example
See example in PREPARE.
