How to query on table returned by Stored procedure within a procedure

Question

I have a stored procedure that is performing some ddl dml operations. It retrieves a data after processing data from CTE and cross apply and other such complex things.

Answer 1

This is not possible.

The only way I can think of is to insert the results from the Stored Proc in to a temp table and query the temp table. This won't work in your scenario as you are returning 4 tables.

Could you not rewrite the query you are interested in as a function or view?

EDIT:

You would do something along the lines of this (only if the Stored Proc returns one table)

Create Proc dbo.usp_FetchUsers

as

begin

Select UserId, UserName
From Users

End
Go

Create Table #t
(
UserId int,
UserName varchar(50)
)

Insert Into #t
Exec dbo.usp_FetchUsers

Select * From #t
Where UserId = 4

drop table #t
