RE: Embedded SQL - Join problems

I am trying to use the following embedded sql code joining two files
via
a left outer join. When I rmeove the highlighted code, I get the
results I am expecting, however, with the code inserted it doesn't
return any records, which tell sme there is probably some sort of
syntax
issue. When I run the sql statement in SQL400 it is fine, and when I
run it through a third party SQL it runs fine. Please help.
