Re: SQL (RETURN MEDIAN?)

Michael, do you realize how long this takes to run when you are dealing with 
a lot of records (9391 to be exact)?
 
 
 
 
 
Thanks,

No burden... that was written on all smiles.  Hard to tell with text.
anyway... you will also need to change the where statement I gave you.  You
need to select the same record for both x and y.

WHERE x.QDDGRP = :WKGRP AND x.QDSDT >= :WKRUNDATE
    AND x.QDINST = :FIINST
    AND y.QDDGRP = :WKGRP AND y.QDSDT >= :WKRUNDATE
    AND y.QDINST = :FIINST

Ciao!

You seriously asked that...  I was hoping that you would be able to plug
and play.

Here's what you want....

SELECT x.QDAPY INTO :WKAPYHIGH
FROM BRDETAIL x
CROSS JOIN BRDETAIL y
WHERE x.QDDGRP = :WKGRP AND x.QDSDT >= :WKRUNDATE
   AND x.QDINST = :FIINST
GROUP BY x.QDAPY
HAVING SUM(SIGN(x.QDAPY-y.QDAPY)) IN (1,0)
ORDER BY x.QDAPY DESC
