Yes. See PREPARE and EXECUTE IMMEDIATE statements.
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,
language sql deterministic not fenced
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 = ' ';
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.
