How to invoke a stored procedure in db2?

To execute a stored procedure in a DB2 database, you can use the following steps:

1. To begin with, create a stored procedure in the database using the CREATE PROCEDURE statement. For example, create a stored procedure named myProc.

CREATE PROCEDURE myProc ()
LANGUAGE SQL
BEGIN
   -- 存储过程的逻辑
END

1. To invoke a stored procedure, you can use the CALL statement. For example, calling a stored procedure named myProc:

CALL myProc();

1. If a stored procedure has parameters, they can be passed when calling the procedure. For example, let’s say the stored procedure myProc accepts a parameter named param:

CALL myProc('paramValue');

Before calling a stored procedure, you must ensure that the stored procedure has already been created in the database.
