resultset of proc in another proc

[helmut woess]

Hello,

i want to use the result set from a stored proc in another stored proc, for
example:

create stored procedure proc1 (@x int) as
declare @tbl (y1 int, y2 int)
insert into @tbl values(@ * @x, @x * @x * @x)
select * from @tbl
GO
--
create stored procedure proc2 (@x int) as
declare @tbl (y1 int, y2 int)
while @x > 0 begin
insert into @tbl select (exec proc1 @x) <-- this is my problem
set @x = @x - 1
end
select * from @tbl
GO
--

I know i could use output parameters. But i want to know if something is
possible with SQL-Server?

thanks,
Helmut

Create a temp table in the first proc (2) and populate that table in
the second proc (1)
Like this

create stored procedure proc1 (@x int) as
insert into #temp values(@ * @x, @x * @x * @x)
select * from @tbl
GO
--
create stored procedure proc2 (@x int) as
declare @tbl (y1 int, y2 int)
create #temp (y1 int, y2 int)
while @x > 0 begin
(exec proc1 @x) <-- this is my problem
set @x = @x - 1
end
insert into @tbl
select * from #temp

select * from temp
---or select * from @tbl -- you can eliminate @tbl in this proc
GO
I don't know why you are calling the second proc you can do all this
stuff in 1 proc like this
-------------------------------------------------------------------------------
create stored procedure proc2 (@x int) as
declare @tbl (y1 int, y2 int)
while @x > 0 begin
insert into @tbl
values(@ * @x, @x * @x * @x)
set @x = @x - 1
end
select * from @tbl
GO

That doesn't help immediately. Because both procs can be called
independently by the client program. But i can put the working part in a
third proc which is called by proc1 or proc2, then i can use your
suggestion.
And i can't put everything in one proc, because in my real application the
first proc should calculate different values for one specific contract, the
second proc should calculate the values for a group of contracts (using
proc1) and present the result in a little different output.

But i am still very interested if it is possible without output parameters
and populated tables.

Helmut
