The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

Look at the COALESCE or IFNULL scalar function - this allows you to specify
a replacement value if the column is null

Subject: SQL "Left Outer Join," was Re: SQL "Right Outer Join"
Ok, so I'm pouring the result of a Left Outer Join into a PF (to be read
by a program that uses Native RLA), and one of the fields "of interest"
is nulled out in several records (as is normal with a Left Outer Join).
If I simply pour it into a file that doesn't allow nulls, it complains
that I'm trying to put null values into fields that don't allow them.
If I change the file I'm pouring my result into, so that it accepts
nulls in the field in question, it works fine, but with an ALWNULL field
as one of the keys, I'm not so sure this thing is very RLA-friendly.
Is there a way that I can change either my query or my PF, so that the
nulls turn into something else before they get to the PF?
