I am attempting to pull only open tickets from my table. Thing is we have duplicate records with different status code in our data
TICKET STATUS
9543 1
9543 5
9543 5
9544 1
9546 1
9547 1
9547 5
I only want the records with a 1 and not a 5 status, so in the above sample, I should only return 9544 and 9546.
Any suggestions are much appreciated.

i think a simple test with an EXISTS and correlated subquery will get you want you want:

With YOURTABLE (TICKET,STATUS)

AS

(

SELECT 9543,1 UNION ALL

SELECT 9543,5 UNION ALL

SELECT 9544,1 UNION ALL

SELECT 9546,1 UNION ALL

SELECT 9547,1 UNION ALL

SELECT 9547,5

)

--the above is just setup data to represent your data , wherever it is.

--data like that makes it easy for anyone to offer helpful posts.

--proposed example is just what is below.

SELECT

*

FROM YOURTABLE OPENTIX

WHERE NOT EXISTS(SELECT

1

FROM YOURTABLE CLOSEDTIX

WHERE CLOSEDTIX.TICKET = OPENTIX.TICKET

AND CLOSEDTIX.STATUS = 5)

AND OPENTIX.STATUS = 1

I think that a GROUP BY is much simpler and probably faster, too.

With YOURTABLE (TICKET,STATUS)

AS

(

SELECT 9543,1 UNION ALL

SELECT 9543,5 UNION ALL

SELECT 9544,1 UNION ALL

SELECT 9546,1 UNION ALL

SELECT 9547,1 UNION ALL

SELECT 9547,5

)

SELECT TICKET, MAX(STATUS) AS STATUS

FROM YOURTABLE

GROUP BY TICKET

HAVING MAX(STATUS) = 1

GO

This is another way of doing it...and I guess the simplest way....:-)

With YOURTABLE (TICKET,STATUS)

AS

(

SELECT 9543,1 UNION ALL

SELECT 9543,5 UNION ALL

SELECT 9544,1 UNION ALL

SELECT 9546,1 UNION ALL

SELECT 9547,1 UNION ALL

SELECT 9547,5

)

Select * From YOURTABLE

Where TICKET NOT IN (Select TICKET From YOURTABLE Where STATUS = 5)

GO

Oh, be careful. For this particular data, that will absolutely work. If they introduce status less than 5 that aren't cause for rejection, it won't.

It's a good idea for the data given. I have a hard time believing that they have no statuses between 1 and 5, though. If they do, the code you posted would produce duplicate ticket numbers. Of course, that may be just what the doctor ordered if there are status other than 1 and 5.

Any suggestions are much appreciated.

The question that begs to be answered here is.... in real life, will there be any tickets with a status other than 1 and 5 and what do you want to do if that's true?

AND OPENTIX.STATUS = 1

Same thing here, ol' friend. This works perfectly if there are interim statuses and they don't mind seeing those interim status or the dupe ticket listings. If they want just a single ticket number for each ticket that's still open, this will probably need to change. Of course, we need to hear from the OP to know for sure.

Scratch that with my apologies. I made a mistake. Your's works fine.

I only want the records with a 1 and not a 5 status

;WITH SampleData (TICKET, [STATUS]) AS (

SELECT 9543, 1 UNION ALL

SELECT 9543, 5 UNION ALL

SELECT 9544, 1 UNION ALL

SELECT 9546, 1 UNION ALL

SELECT 9547, 1 UNION ALL

SELECT 9547, 5)

SELECT TICKET

FROM SampleData

WHERE [STATUS] IN (1,5)

GROUP BY TICKET

HAVING COUNT(*) = 1

AND MIN([STATUS]) = 1
