There is no such a thing

SQL

SELECT Col1, Col2 FROM EXEC MY_SP @PRM = 1

What you have to do is declare a temporary table, insert the result of the EXEC into it, than select from that temporary table...

SQL

CREATE PROC MY_SP (@PRM INT)
AS
  SELECT @PRM AS ONE, 2 * @PRM AS TWO

SQL

DECLARE @RESULT TABLE (ONE INT, TWO INT)

INSERT INTO @RESULT
EXEC MY_SP @PRM = 1

SELECT ONE FROM @RESULT
