Hi everybody,

I have a query, which executes too long (though I executed it through PCAnywhere, but it should not be a factor here):
SELECT oJC.CurState as State, CMRView.*, Date, Mortgage, Source, ;
ParentCode as Lender, extrWeek, extrYear ;
FROM TranMstr inner join Lookups!Lender on TranMstr.Lender=Lender.Code ;
Inner Join SiteMstr on TranMstr.PropID=SiteMstr.PropID ;
Inner Join CMRView on SiteMstr.town=CMRView.town ;
 where (between(date,ctod('01/01/2001'),ctod('06/30/2001')) ) ;
and between(Mortgage,1,1000000000)  ;
INTO TABLE \redp\work\CMR\CMR_0FE18SEWQ
Here is sys(3054) result:
Using index tag Date to rushmore optimize table tranmstr
Using index tag Mortgage to rushmore optimize table tranmstr
Using index tag Deleted to rushmore optimize table tranmstr
Rushmore optimization level for table tranmstr: full
Using index tag Deleted to rushmore optimize table lender
Rushmore optimization level for table lender: full
Using index tag Deleted to rushmore optimize table sitemstr
Rushmore optimization level for table sitemstr: full
Rushmore optimization level for intermediate result: none
Joining table tranmstr and table sitemstr using index tag Propid
Joining intermediate result and intermediate result using temp index
Joining table lender and intermediate result using temp index
Selected 13446 records in 368.26 seconds

        375
        475
        575
        675
        775
        875
        975
BTW, what do the numbers (275, 375, etc.) show here?

Do you have suggestions to optimize it (don't suggest to drop deleted tags :))?

Thanks a lot in advance.
If it's not broken, fix it until it is.
