[AccessD] Query does not return all records

OK here is what I get. Apparently 5 records were added to the master table (dbo_DSS_CompletionMaster) today so it has 2090 records. If I use the criteria of <1/1/2001 I get 1037 records. If I use the criteria of >1/1/2001 I get 1046 records. PID is a required field thus exists for all records in both tables. It is a unique field in the table dbo_DSS_CompletionMaster. There are 2083 unique PID's in the dbo_StatusChanges1 table.  The dbo_DSS_StatusChanges1 table has a total of 85508 records.

Thanks for the assistance.

If you change the HAVING line to read >#1/1/2001#, do you get 1039 records?

Are any PID fields null? If so, you may have to use the following

ON NZ(dbo_DSS_StatusChanges1.PID,0) = NZ(dbo_DSS_CompletionMaster.PID,0)
