RE: Creating an SQL UDF on a procedure

Thanks for your reply Gary
I am not too sure whether or not I am understanding what you are telling me.
How can a SQL User Define Function created over the procedure change the user space when used as part of a view, or as part of an SQL script?

How about something like this...

o Have the program leaving the file open run in a named activation group.
o Each time it runs have it check a control structure to see if it should close down.
o Your additional parameter returns a value to the invoking program telling it to reclaim the activation group and run the program again.

Using a pointer to a user space makes accessing the control structure virtually interactive. You obtain the pointer once and just check the value. When an external process changes the user space your program know about it almost instantly. It is also handy when you have copies of the program running in multiple jobs.

But then we have to inform everyone who will use this function going forward of this procedure.
I am not saying it's not feasible, just that eventually someone is not going to do that, and then we are back to my original questions.

Hi Chris
Nice idea but how do we send -1 down when using this function within a view, or sql?

Instead of a second parameter, could a special order number, say -1 trigger the close?

Subject: Creating an SQL UDF on a procedure

Hi everyone
We have a procedure that leaves the files open until the procedure is called one final time with an extra parameter to close the files For example, within an RPG program

Ordertype = getOrderType(Ordernumber);
And then at the end of the RPG program

Ordertype = getOrderType(Ordernumber: Closefiles);

We now need to create a function on this procedure. I don't have a problem creating the function. My concern is that the "final" call - namely Ordertype = getOrderType(Ordernumber: Closefiles); - will NOT be done (or is there a way to do it).
My questions to the panel are - is this a cause for concern?
Will this be a problem at some time?
