this is the code I used to retrieve a record set.
SELECT
p.HPROP,
p.STYPE,
p.SVALUE,
NSFFee = CASE WHEN p.STYPE = 'nsffee' THEN p.hvalue END,
SecDepIntRate = CASE WHEN p.STYPE = 'DDEPOSITINTEREST' THEN p.hvalue END
FROM PROPOPTIONS P
WHERE p.hprop = '240' and p.STYPE IN ('nsffee','DDEPOSITINTEREST')
my result is as followed
HPROPSTYPE SVALUENSFFeeSecDepIntRate
240DDEPOSITINTEREST0NULL3000.0000
240NSFFee 50.0000NULL
is there a way to get only one record or am i doint this wrong.

You could use SELECT TOP 1, but I don't know if that's what you really want.

If you have more than one row meeting your search criteria, you should either want to return both or further refine your WHERE clause to return only the specific one you want. If you do want only one of them (say the last one added) and use TOP, make sure you include an ORDER BY clause to make the results consistent.

That is not going to work for me.

That is not going to work for me.

So, what is it that you actually want? which of the two row do you want returned or do you want to somehow combine the rows? Be specific.

The ladder I want to combine the rows into one record.

the code

SELECT

p.HPROP,

p.STYPE,

p.SVALUE,

NSFFee = CASE WHEN p.STYPE = 'nsffee' THEN p.hvalue END,

SecDepIntRate = CASE WHEN p.STYPE = 'DDEPOSITINTEREST' THEN p.hvalue END

FROM PROPOPTIONS P

WHERE p.hprop = '240' and p.STYPE IN ('nsffee','DDEPOSITINTEREST')

the result

HPROPSTYPE SVALUENSFFeeSecDepIntRate

240DDEPOSITINTEREST0NULL3000.0000

240NSFFee 50.0000NULL

what I'm looking for is

hprop nsffee SecDepIntRate

240 50.0000 3000.0000

Like this?

WITH PriorResults (HPROP, STYPE, SVALUE, NSFFee, SecDepIntRate)

AS (

SELECT 240, 'DDEPOSITINTEREST', 0, NULL, 3000.0000

UNION ALL SELECT 240, 'NSFFee', 0, 50.0000, NULL

)

SELECT HPROP

,NSFFee=SUM(NSFFee)

,SecDepIntRate=SUM(SecDepIntRate)

FROM PriorResults

GROUP BY HPROP

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.

Looks like it. Heh... we make a hell of a tag team. I'll flush out the requiremments, you write the code. 🙂

Yeah, aren't we though?

I did have to make an assumption (the 0 in the second row of the set up data) as the OP only provided 4 data columns in that row but 5 in the first row.

Agreed.

Jeff, you and Dwain may have missed the preceeding part of this case.

@dmarz96, it's much easier to see what you are trying to do, now that I've seen both threads. Often, breaking a case up into different threads like this causes confusion and fragmented replies as no single thread has all of the information required to put together a solution.

Indeed I did but it looks like you've got it covered.

I think this is the statement that caused me to think only one of the rows was required.
