Re: SQLRPGLE won't compile...

Ok...The other thing I noticed is that you are selecting two fields in the
cursor Freight.  Your DS has around 12 fields...eliminate the extra
fields.

Regarding performance...change your Where clause to: WHERE FHDDAT between
:FDATE AND :TDATE.  This statement is a little bit easier to code and to
follow.  I also believe it will help from a performance standpoint.  This
statement is inclusive of the FROM and the TO date.

I also noticed you have DISTINCT coded.  I'm assuming that you have
multiple FHOT, FHPRO and you are trying to pair these down.  If not...nix
the distinct.  Do you have an index already ordered by FHOT & FHPRO?  The
query optimizer will probably require the addition of FHDDAT to the index
also.

Once you get the program to compile...place it in debug and place a
breakpoint after the OPEN statement....check the job log...it will tell
you which access path it used or it will tell you what index it needs to
perform efficiently.

We'll keep plugging until we get it.
