Re: Another SQL-newbie UDF question: qualifying with a library passed as a variable

Sorry, I had not been following. I envisioned an RPG or other HLL program doing the work of the UDF.

Hmm. I'm not entirely sure how (or even if) this would work for the
issue at hand:

What I have is along the lines (simplified and censored) of:

create function displayval(i_fldid NUMERIC,
i_key VARCHAR(10))
returns varchar(50)
language sql deterministic not fenced
begin
declare result char(50);
declare tbl char(11);
if i_key = ' ' then return ' '; end if;
SELECT TBLID INTO TBL from FOO where dfid = i_fldid;
select DEF INTO result from BAR
where PTBLE = substring(tbl from 1 for 3)
and PCODE = substring(i_key from 1 for 5)
and STBLE = ' ' and SCODE = ' ';
RETURN RESULT;
END


What I'd like to have would add a third parameter:

create function wintouch/displayval(i_fldid NUMERIC,
i_key VARCHAR(10) i_lib varchar(10))

and then qualify FOO and BAR with i_lib.

Or otherwise guarantee that FOO and BAR are both the ones in i_lib, and

not from some other library.
