Re: SQL on 4.3 doubling up result set.

[Danny.Jahr@xxxxxxxxxx]

This is from the DB team at SupportLine in Rochester.  Maybe it will help, maybe
not.

The most common cause of a query returning duplicate records is that there is
more than one record in the
secondary file that matches the comparison test. The proof is to query only the
secondary file using the
same selection criteria as the join. You will probably receive duplicate records
 indicating that the file does
have duplicate records that match the selection criteria.

To determine the number of records that query joins when you have duplicates,
multiply the number of
records from each file involved in the join operation. For example, if the first
 file has 2 records, the second
file has 3, and the third file has 4, the join operation would return 24 records
 (2*3*4).

Change the join comparison test so that the selection is more descriptive and
results in a record-to-record
match. Or, use record selection criteria against the records to select the
desired records from the result set.

 Subject: SQL on 4.3 doubling up result set.                  
                                                              







Has anyone had trouble with V4R3 and SQl?  I have a client that is having
the result set returned twice.  Even a count(*) returns two count records.
This is happening on interactive and embedded sql operations.  However,
Query seems to be OK (very strange).  This is a new 730 with 4.3 that just
went in over the weekend.

Any assistance would be greatly appreciated.

Thanks

john
