How can I put an If statement saying If # RECORDS returned from the query below
IF # records returned is > 1 then
SUM(rmstranamt) AS rmstranamt10
ELSE
rmstranamt AS rmstranamt10

here's my statement
-------------------------
SELECT RMSFILENUM,
rmstranamt AS rmstranamt10 <-----If statement goes here base on if the amount of records found in select is >1 or not
FROM RFINANL
WHERE RMSTRANCDE = '10'
GROUP BY RMSFILENUM, rmstranamt
) AS rf10 ON rf10.RMSFILENUM = rm.RMSFILENUM

I want to return sum(rmstranamt) AS rmstranamt10 in cases where the same query produces > 1 records
In other words if this:
SELECT RMSFILENUM,
rmstranamt AS rmstranamt10
FROM RFINANL
WHERE RMSTRANCDE = '10'
GROUP BY RMSFILENUM, rmstranamt
produces > 1 records, then I don't want to return rmstranamt AS rmstranamt10, I want to return sum(rmstranamt) AS rmstranamt10

If number of records = 1 then sum(rmstranamt) = rmstranamt.

So just use sum(rmstranamt).

try this in place of your code.

SELECT RMSFILENUM,

sum(rmstranamt) AS rmstranamt10 1 or not

FROM RFINANL

WHERE RMSTRANCDE = '10'

GROUP BY RMSFILENUM

Hi, I can´t understand what are you trying to do... if your query returns just a single record sum(x) = x because there is JUST ONE record... so, you doesn´t need to check for the number of records... also, to return just de field and not the sum, you have to put it in the group clause...

Checking conditions into a query is well done using CASE clause... see BOL for info on that.

Good Luck

I'm also not sure what you are trying to do but if you have several records where RMSTRANCDE = '10' and you want to return 0 for zero records and return 1 for more than 1 record then try this

SELECT

RMSFILENUM,

CASE WHEN COUNT(*) > 1 THEN 1 ELSE 0 END AS rmstranamt10

FROM RFINANL

WHERE RMSTRANCDE = '10'

GROUP BY RMSFILENUM

SELECT RMSFILENUM, SUM(rmstranamt) AS [rmstranamt10]

FROM (SELECT RMSFILENUM, rmstranamt AS rmstranamt10

FROM RFINANL

WHERE RMSTRANCDE = '10'

GROUP BY RMSFILENUM, rmstranamt) x

GROUP BY RMSFILENUM

For my money I'd go with Sergiy - why bother to count # of rows - just sum(rmstranamt) should be adequate...

Unless it it the sum of unique rmstranamt's that is required
