can this be done??? I would like to make a Stored Procedure that builds a Select statement, based on the results of another SP (which could change)

Sorry for the blank post.
Yes. You can take the output of one sp, and place it into a temporary table. Then process through that temporary table building dynamic SQL to build the select statement you desire.

Hey Greg, thanks for the reply. I looked at your SQL Server Examples page, but couldn't figure out what example were you referring to that would help out with this task. ? I thought I could dump the SP results into a temp table, but have had trouble figuring out how. Is it necessary to create the table first?
November 6, 2002 at 8:40 am
I have yet to put one out on the web. Try this example:
create table #tmpwho (
spid int,
ecid int,
status char(20),
loginame char(100),
hostname char(100),
blk int,
dbname char(100),
cmd char(100))
go
INSERT INTO #Tmpwho EXECUTE sp_who
go
select * from #tmpwho

still searching...
Unfortunately, the code you included in your last post assumes that I already know the Result COLUMNS of my SP. I don't have any idea what the columns that will be returned are. I don't actually care about the data that is returned. All I really care about are the names of the columns (Headers).

Here is something I think might work for you:
select * into #tmptest
FROM OPENROWSET('SQLOLEDB','<yourserver>';'<user>';'<password>',
'exec sp_who ') AS a
select column_name from tempdb.information_schema.columns where table_name like '#tmptest___%'

Thank You, Greg!
That's what I was looking for. I think you saved me a couple hours of headache there! I am surprised that this was not one of the FAQs. This is not the first time I have wanted this functionality.
OF course, as soon as I got this figured out, we realized it won't be necessary. But, now I know, and knowing is at least half of the battle.

Hi Greg,
I've run into the same problem and when applying your solution I get an error message. Could u please take a look at it and give me a hint what am I doing wrong here...

Try specifying the Database and Owner of the stored procedure e.g.
EXEC pubs.dbo.DRFExportOMC
November 19, 2002 at 3:20 am
Tnanx for the reply, it did work. ... but now I'm coming up with the following error:
**************************************
USE ct10002G

select distinct * into #tempalex

**********************************

Column names in each table must be unique. Column name 'omcVersion' in table '#tempalex' is specified more than once.
Tnanx much,

Alex,
the select statement in your stored procedure lists O.OMCVersion twice (col 1 & 8). If you actually need the same value twice, try aliasing the second instance of the column with an " as OMCVersion2"
November 20, 2002 at 1:51 am
THANX, I'm still havin' some troubles with this sp. At the moment I have the query that gets the result from another stored procedure (DRFExportOMC) and outputs all the column names needed, but it shows them sorted by ktt.label column... at the same time I don't need the output to be sorted at all (to actually have them in the sequence they come out in the initial stored procedure output. Like this:
/**********************************************************
The initial stored procedure: DRFExportOMC
*********************************************************/
CREATE Proc dbo.DRFExportOMC (
@i_AltId tinyint,
@i_NelId smallint
)
As

IF @i_Nelid IS NULL SET @i_Nelid = @i_Altid * 4
SELECT distinct O.omcVersion,
CAST( 0 AS binary(4) ) as eqtVersion,
O.OMC,
O.CooRef,
O.TemplateRef,
O.omcArchitecture,
O.omcLanguage,
O.pcmKind,
O.algoA,
O.cellTiering,
O.GPRS,
O.ASCIMode,
O.ss7Protocol,
O.gsmProtocol,
O.microAlgoType,
O.comment

AND NEL.rowId = O.rowId
WHERE @i_AltID = O.altId
AND IsGhost = 0-- OMC ghost are not exported
AND NEL.nelid = @i_NelId
END
/* The output comes out with the following column names sequence.... (from left to right, just like in any table */
omcVersion
eqtVersion

CooRef
TemplateRef

When I run my final query:
USE ct10002G
GO
drop table #tempalex
select distinct * into #tempalex
FROM OPENROWSET('SQLOLEDB','N1244';'sa';'','exec CT10002G.dbo.DRFExportOMC @i_AltId = "1", @i_NelId = "1"')
as a
select distinct tisc.column_name
from tempdb.information_schema.columns as tisc
join PDSKeywordTranslationTable as ktt
on tisc.column_name = ktt.keyword
join PDSParameterDefinitionTable as pdt
on pdt.keyword = ktt.keyword
where tisc.table_name like '#tempalex___%' and pdt.module = 'GSM'
/* The output is as follows:

omcVersion
ss7Protocol
OMC

microAlgoType
algoA
omcArchitecture

CooRef
(11 row(s) affected)
As u can see the ORDER BY is performed as if it was set up to be done by default. Is there a way to solve it? Pls help, if anyone ran into this before...
Thnx in advance,
Alex

Alex,
If I'm understanding you right, you want the final output to be in column order from the original stored procedure.
To do that, simply add an order by clause to your final query:
select distinct tisc.column_name
from tempdb.information_schema.columns as tisc
join PDSKeywordTranslationTable as ktt
on tisc.column_name = ktt.keyword
join PDSParameterDefinitionTable as pdt
on pdt.keyword = ktt.keyword
where tisc.table_name like '#tempalex___%' and pdt.module = 'GSM'
ORDER BY TISC.ORDINAL_POSITION
