I have recently started working on sql server programming.
My dynamic function is as under.Same gives syntax error when Iam trying to assign the dynamic sql value to a variable.

CREATE FUNCTION BSMTest (@DisplayCol VARCHAR(30), @TrnNo INT, @TName VARCHAR(30))
RETURNS VARCHAR
AS
BEGIN
DECLARE @sqlQuery VARCHAR(2500)
DECLARE @Output VARCHAR(2500)
SET @sqlQuery = ' SELECT '+@DisplayCol+' FROM '+@TName+' WHERE TransactionNo IN ('+Quotename(@TrnNo,'''')+')'
SET @Output=Exec(@sqlQuery)
RETURN @Output
END

The sql query which is built is
select accountNo from vw_transactions_mortgages where TransactionNo in ('100004')

It returns a single output.

can someone help me out if Iam following a wrong process
regards
bhagwan"

The problem is, you can't use dynamic SQL in udfs. See CREATE FUNCTION in BOL for more details of what is and isn't allowed in udfs.
