Frank, As mentioned by others earlier, there seems to be a mismatch in the fields retrieved and the DS declared. Please try to declare only the fields you fetch as the DS or try to declare for all the fields in the DS for it to compile. As also mentioned earlier, the DIM could not be used until v5r3. I have successfully used occurs. In the code, I see couple of unnecessary End-Exec in the code. I presume it is because this is a snapshot of the code. I am not certain if you are using the SQLCA to determine the EOFFLG. SQLERRD(3) will return the number of rows fetched. SQLERRD(5) will return the DB2_LAST_ROW (100 if eof) I have never found any particular reason (other than say a subfile) to fetch 50 records at a time, since you have to loop through them individually to process them any way. Is there any reason for not fetching in a loop? As I see it, the cursor is declared and retained till the entire process is finished and there may not be any process/memory gain by fetching 50 records at a time.

I need those fields in my " 1 DO 50 X " processing loop. I'm using the SQL fetch to grab 50 records, process the records, write records to a file, then go get the next 50 records. This loop was created for the SQL block fetch. I'd rather not use a loop with in a loop if possible. Is there a simpler method of getting all the data I need at 1 time and just loop through those records, instead of getting just 50 at a time and looping through those 50, then grabbing another 50?

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. Regards, Russell Conerly Tupelo, MS >> >> The program below(only relevant code included), won't compile.
