Dynamically create table when executing a stored procedure
-
Hi all,
How can i create a temporary table on executing a procedure.
ex:
exec sp_who
how to dinamically create temporary tabe on executing the above procedure

Do you mean you want to store the resultset from the procedure in a temporary table? If so, it can't be dynamically created. You can however create it 'manually' and store the results there.
CREATE TABLE #who ( define all columns that exist in the output of sp_who )INSERT INTO #who EXEC sp_who
-
Thanx Chris,
This is not what i need i dont want to define the columns that exist in the output
Is there anycommand that we can create a table without defining the columns.

I don't say it can't be done... but it would take so much work that I think it would be simpler to create a table with dummy col names (col001, col002...). I assume here that this is for general knowledge, do you have an actual situation in mind?
-
The code snippet below is what I use to sort the results of sp_who2. This is what Chris suggested. It is specific to sp_who2.
If you need to work with the results of a stored procedure known at design time, this should work. The only maintenance required is changing the table definition if the output of the stored procedure changes.
Are you wanting a more generic solution that will store the results of some procedure that is not known at design time (maybe passed as a parameter)?
------------------------------
DECLARE @Field as varchar(15)
set @Field = 'DBName'
DROP TABLE #SPWHO
CREATE TABLE #SPWHO
(SPID int,
Status varchar(100),
Login varchar(100),
HostName varchar(100),
BlkBy varchar(100),
DBName varchar(100),
Command varchar(100),
CPUTime int,
DiskIO int,
LastBatch varchar(50),
ProgramName varchar(100),
SPID2 int)
INSERT INTO #SPWHO
EXEC master.dbo.sp_who2
SELECT * FROM #SPWHO
ORDER BY DBName
------------------------------

UPDATE: My previous post included some stray code from an experiment. There is no need for the lines
DECLARE @Field as varchar(15)
set @Field = 'DBName'
-
This seems like the most evil idea... but it would work :
Select * into NewTable from Openrowset (linkedserverinfo, 'Exec procedure...')
-
Hi ,
Thanx Johnson for ur effort but i mentioned before dont define the table structure before.
Hi Remi,'
But openrowset doesnt work.

I'll try to make it work tomorrow.. but I know it's possible.

Remi,
One attribute of Openrowset requires the connection to return columns. This may be the problem when executing sp_who or sp_who2 depending on the provider used.
Raj,
The code was an example if you could predefine the table. The question was are you looking for a solution specific to sp_who or something more generic that will handle procedures identified at run time?

Here's something that I just tested:
I created a linked server on my machine :
exec sp_addlinkedserver @Server = 'TestLinkServer',
@srvproduct = 'SQLServer OLEDB Provider',
@provider = 'SQLOLEDB',
@datasrc = 'CASSANDRA'
Then did the following:
Select *
into #NewTable
from Openquery(TestLinkServer, 'Exec sp_who')
select * from #NewTable
drop table #NewTable
worked like a charm....
**ASCII stupid question, get a stupid ANSI !!!** -
Yup, I was trying to make it work without the self-linked server but looks like there's no way around... unless we ask Noeld
-
sure we can ask noeld (not that there's anything wrong with that) - but wasn't he on the other post that had the exact same question...????
will go and check!

Don't think so. That post is somewhat incomplete at the moment.

Remi,
Yes you can use Openrowset:
Select *
into #T1
from Openrowset('SQLOLEDB','Trusted_connection=yes;Data Source=YOURSERVER','exec sp_who') dt
select * from #T1
drop table #T1
-- You need to have MSDTC ON and the server set to allow remote server connections but other than that it should be OK
