CREATE PROCEDURE

Function Description

Creates a stored procedure.

Precautions

Compared with the original MogDB, Dolphin modifies the CREATE PROCEDURE syntax as follows:

1. The LANGUAGE option is added.
2. The syntax compatibility item [NOT] DETERMINISTIC is added.
3. The syntax compatibility item { CONTAINS SQL | NO SQL | READS SQL DATA | MODIFIES SQL DATA } is added.
4. The syntax compatibility item SQL SECURITY { DEFINER | INVOKER } is added.
