Hello everybody,
Someone helped me earlier with this TCL trigger function:
create or replace function tlow() returns trigger as '
set NEW($1) [string tolower $NEW($1)]
return [array get NEW]'
language 'pltcl';
I use it to force lowercase of values inserted in the db. There is one
problem though, if the parameter is absent, the function will give an
error message. I would like it to rather check for null before tolower
is applicated. In semicode:
if ($1 <> NULL) {
set NEW($1) [string tolower $NEW($1)]
}
return [array get NEW]'
but I have no idea how to do this in TCL. Can somebody please tell me?
Thanks a lot!
