Err, what do you mean by 'select statement of the stored procedure'?

I assume this is a table-valued UDF. If so, then it's used in the FROM clause of a select

SELECT FunctionColumn1, FunctionColumn2, ... FROM dbo.UserDefinedFunctionName(Parameter1, Parameter2, ...)

Yes,This is UDF. I want to use this function in my stored procedure.

FUNCTION dbo.Blabla

(

@DE1 Varchar(100),

@DE2 Varchar(100)

)

RETURNS TABLE

AS

RETURN

(

SELECT

substring(CAST(COL1 AS VARCHAR(20)),1,CAST(CHARINDEX('-',COL1) AS VARCHAR(20)) -1) AS ,

substring(COL1,CHARINDEX('-',COL1)+1,(Len(COL1))) AS [lCode]

FROM [Emp] A

Where DE1=@DE1 and DE2=@DE2

AND DT = (Select MAX(DT) From dbo.Emp B Where A.DE1=B.DE1 and A.DE2=B.DE2)

)

Now i want to use this function in my stored procedure to get code and lcode values?

How to approach this based on parameters?

Since your UDF returns a table, you could probably use CROSS APPLY to pass values from the other table (the source for the two parameters) and then return the whole thing in one result set. Kind of hard to tell with the sketchy description of the problem.

With the really vague question and lack of details, hard to say anything useful. Can you explain further?
