Experts:

I have this in my table:

ORDERID    PAYID  
1000              1
1000              2
1000              2
1000              2
1001              1
1001              2
1001              2
1002              2
1003              2
1003              2

The 1's represent APPROVED,....the 2's mean NSF or ....non sufficient funds. We didn't get paid.....

I want to achieve this:

ORDERID     NSFCOUNT
1000                    3
1001                    2
1002                    1
1003                    2

How can I do this...?
Thanks

It depends -- if you don't need to show a zero count, that is, you want to list them *only* those rows that had at least one NSF, then you can use srafi78's method.

SORRY.....I "over-simplified" it too much.........see below:

I have this in my table:

ORDERID    PAYID      DATE
1000              1           01/01/07
1000              2           01/02/07
1000              1           01/03/07
1000              2           01/04/07
1000              2           01/05/07
1000              2           01/06/07
1001              1           01/01/07
1001              2           01/02/07
1001              2           01/03/07
1001              1           01/04/07
1001              2           01/05/07
1001              2           01/06/07
1002              2           01/01/07
1003              2           01/01/07
1003              2           01/02/07
1003              1           01/03/07
1003              1           01/04/07
1003              2           01/05/07

The 1's represent APPROVED,....the 2's mean NSF or ....non sufficient funds. We didn't get paid.....

I'm only concerned with the LATEST or MOST RECENT "2's"...I need to be able to COUNT the 2's starting fromt he most RECENT one BACKWARDS....up to the LAST PAYMENT RECIEVED. We will be calling customers based on the Number of NSF's received so I only need to count the most recent series.

I want to achieve this:

ORDERID     NSFCOUNT
1000                    3
1001                    2
1002                    1
1003                    1

Hope it makes sense..the key is that IF they make a payment to us...represented by a '1' then this would reset their NSF COUNT. We are only concerned about their LATEST batch or series of NSF's and being able to COUNT them up.

THANK YOU for your expertise!!

Select ORDERID, COUNT(PAYID) 'NSFCOUNT' FROM urTable t1 WHERE PAYID = 2
AND  t1.DATE > (SELECT MAX(DATE) FROM urTable WHERE PAYID = 1 AND t1.ORDERID = t2.ORDERID GROUP BY ORDERID)
GROUP BY ORDERID
