quote_literal Simple question
Hi all,
I did a stored procedure and ran into this small problem.
Here itemIdValue may be null and I would have expected quote_literal to
returns null as a string or the value quoted. For now I think it returns a
real null. This causes my function to crash.
insertStatement:= ''INSERT INTO IL ( ILNUM, ILTYPE, ILICNUM, ILRRNUM, ILQTE,
ILPRIX, ts ) VALUES ( '' || idValue ||'', ''|| typeValue ||'','';
insertStatement:= insertStatement ||
quote_literal(itemIdValue) || '','';
insertStatement:= insertStatement ||
I haven't found an existing function to handle this case and I hate
reinventing the Wheel... Is there a function that already handles that?
For now I worked around this by using the COALESCE function.
COALESCE(quote_literal(itemIdValue),'' null'') || '','';
insertStatement:= insertStatement ||
Thanks for your help
/David

You should be able to use a CASE WHEN statement inside this expression and
test for a null itemIdValue. If it is null the you can return ''NULL'' else,
return itemIdValue.
