Re: Can a UDF call in a SELECT be library-qualified? Or have I just wasted most of my afternoon pursuing a wild goose?

I wrote:
I just spent the afternoon bypassing the whole "pass the library to the UDF" thing by way of a strategy that requires the UDF calls in a VIEW definition to be library-qualified.

Now, I'm getting error messages to the effect of "Column FOO not in specified tables," where FOO is the library where the specific instance of my DISPLAYVAL UDF lives, and with which I'm qualifying the calls thereto, e.g., FOO/DISPLAYVAL(9106, BAR).

Have I just wasted my afternoon doing something not permitted in an SQL SELECT?

Or is the UDF guaranteed to be the one found at view creation time, making qualification unnecessary so long as the "right" one was the first one that RUNSQLSTM found when it created the view?

In which case, only the hour I spent painstakingly qualifying the UDF calls would have been wasted?
