SQL Server 2012 :: Call Stored Proc Once Per Each Row Of A Table Without Using CURSOR

I have a situation where I need to call a stored procedure once per each row of table (with some of the columns of each row was its parameters). I was wondering how I can do this without having to use cursors.

Here are my simulated procs...

Main Stored Procedure: This will be called once per each row of some table.

-- All this proc does is, prints out the list of parameters that are passed to it.

CREATE PROCEDURE dbo.MyMainStoredProc (
@IDINT,
@NameVARCHAR (200),
@SessionIDINT
)
AS
BEGIN

[Code] ....

Here is a sample call to the out proc...

EXEC dbo.MyOuterStoredProc @SessionID = 123

In my code above for "MyOuterStoredProc", I managed to avoid using cursors and was able to frame a string that contains myltiple EXEC statements. At the end of the proc, I am using sp_executesql to run this string (of multipl sp calls). However, it has a limitation in terms of string length for NVARCHAR. Besides, I am not very sure if this is an efficient way...just managed to hack something to make it work.
