Question

This is a question about some stored procedures running on MSSQL 8 (I think that’s SQL Server 2000).

I have two stored procedures left by my predecessor at the company.

The “Modify” window for the first procedure looks something like this:

ALTER PROCEDURE [dbo].[Proc1]
    @ID,
    @someBool

AS
BEGIN

SELECT colA, colB, colC
FROM   myTable
WHERE  colA = @ID AND colB = @someBool

END

The second procedure is very similar, being something along the lines of:

ALTER PROCEDURE [dbo].[Proc2]
    @ID

AS
BEGIN

SELECT colA, colB
FROM   myTable
WHERE  colA = @ID AND colB = FALSE

END

Obviously, the real procedures are more complicated than this and require a lot more maintenance when changes are made.

Rather than maintaining these two queries separately, which pretty much sucks, I was wondering if there was any way to simply have Proc2 do something along the lines of:

ALTER PROCEDURE [dbo].[Proc2]
    @ID

AS
BEGIN

EXEC Proc1(@ID, FALSE)
"drop colC"
"return modified result"

END

Any ideas on the best way to go about this?

Answer 1

Maybe something like this?

CREATE TABLE #Proc1TempResults
(
    ColA INT, --OR WHATEVER DATA TYPE
    ColB INT,
    ColC INT
)

INSERT INTO #Proc1TempResults (ColA, ColB, ColC)
EXEC Proc1 @ID, 0

SELECT ColA, ColB
FROM #Proc1TempResults
