TSQL: Call a stored procedure from another stored procedure and read the result

Question

I have a stored procedure that, ending with a SELECT, returns a recordset. I can call it within anoher stored procedure like this:

EXEC procedure @param
         


        

Answer 1

AFAIK, you can't. What you probably want to do is use a function for your first (or both) procedures. Functions can only return one thing, but they can return a table. Stored procedures can return multiple results, but not to other functions/stored procedures.

e.g.:

CREATE FUNCTION [dbo].[fn_GetSubordinates] (
    @sPersonID VARCHAR(10),
    @nLevels INT
)
RETURNS @tblSubordinates TABLE
(
    Person_Id VARCHAR(10),
    Surname char(25),
    Firstname char(25)
)
AS
BEGIN
    ...
