RECREATE PROCEDURE

Syntax

!! See syntax of CREATE PROCEDURE for further rules !!

The RECREATE PROCEDURE statement creates a new stored procedure or recreates an existing one.If a procedure with this name already exists, the engine will try to drop it and create a new one.Recreating an existing procedure will fail at the COMMIT request if the procedure has dependencies.

Warning

Be aware that dependency errors are not detected until the COMMIT phase of this operation.

After a procedure is successfully recreated, privileges to execute the stored procedure, and the privileges of the stored procedure itself are dropped.

RECREATE PROCEDURE Example

Creating the new GET_EMP_PROJ stored procedure or recreating the existing GET_EMP_PROJ stored procedure.
RECREATE PROCEDURE GET_EMP_PROJ (
  EMP_NO SMALLINT)
RETURNS (
  PROJ_ID VARCHAR(20))
AS
BEGIN
  FOR SELECT
      PROJ_ID
    FROM
      EMPLOYEE_PROJECT
    WHERE
      EMP_NO = :emp_no
    INTO :proj_id
