How can we View the DB2 Procedure (I mean what logic they have writte开发者_如何学Cn ) and How can we execute the DB2 Procedure and just see the output of the procedure using DB2

DB2 stores the system related tables under syscat schema. So a query on syscat.routines will give you the Stored Procedure content.

A typical example: if you got a stored procedure by the name update_employee, the below query works:

select text from syscat.routines where routinename = 'update_employee'

Using the db2 describe command, you can see the table schema and can determine which all columns you want to view.

Invoking a stored procedure is already answered in "How to call a stored procedure in IBM System i Access for Windows GUI Tool" and you can refer that. (Eg: call myStoredProc(parm1, parm2, ?); )

I suggest you read the DB2 stored procedure details from IBM website.
