Multiple Result Sets From A Stored Procedure

I have a stored procedure like the following. This returns 2 result sets, however i only want it to return 2nd (SELECT SomeField FROM SomeTable). How is this done? Note - it is not possible to change 'SomeSPThatReturnsAnIntAndAResultSet '



CREATE PROCEDURE [dbo].[SomeSP]

@SomeParam int

AS

BEGIN

SET NOCOUNT ON;

declare @SomeScalar int

exec @SomeScalar = SomeSPThatReturnsAnIntAndAResultSet @SomeParam

if @SomeScalar = 0

BEGIN

SELECT SomeField FROM SomeTable

END

END
