I get an error "There is already an object named 'PK_#temp' in the database". because i have created a primary key on temp. table in a stored proc and 2 or multiple users run it at the same time i get above error message. If only one user would run the SP then there is no problem.
Challenge is how to fix this.
Question, can't there be Primary key on the temp table. If so can Sql server 2005 manage if i dont use primary key name or how does it work. Let me know. See the below code from the SP.


--this temp table created on the fly in the SP. 2 users run the SP 
--sametime is causing it to fail or should i do check if table(&PK) 
--exists at first place and then create table.. Let me know.
Create table #tempMain
(
SrOfferID Int NOT NULL CONSTRAINT [DF_#tempMain_SrOfferID]  DEFAULT (0), 
SrOfferScheduleID  Int NOT NULL CONSTRAINT [DF_#tempMain_SrOfferScheduleID]  DEFAULT (0), 
FacultyID Int NOT NULL CONSTRAINT [DF_#tempMain_FacultyID]  DEFAULT (0), 
StartDate  Datetime,
EndDate  Datetime,
OfferDays char(10),
ShowDay  char(3000),
ShowMonth char(3000)
CONSTRAINT [PK_#tempMain] PRIMARY KEY CLUSTERED 
(
[SrOfferID] ASC,
[SrOfferScheduleID] ASC,
[FacultyID] ASC
) ON [PRIMARY]
) ON [PRIMARY]

Forgot to tell this.. I already do the checking before creating temp table..
--Drop #temp table if exists
 
IF  EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[dbo].[PK_#tempMain]') AND type = 'PK')
	Begin
	ALTER TABLE [dbo].[#tempMain] DROP CONSTRAINT [PK_#tempMain]
	End 
 
If exists (select  * from tempdb.dbo.sysobjects o where o.xtype in ('U')  and o.id = object_id(N'tempdb..#tempMain'))
	Begin
	Drop table #tempMain	
	End 
--After this i create the table as in above code snippet

you shouldn't need to drop the constraint first...try this:

if object_id('tempdb..#tempMain') is not null
drop table #tempmain

create table...

That works chapmandew, so that means when i drop a temp table. Primary Key constraint on the temp table will be dropped automatically??? or explain me what's my mistake.

yep, when you drop a table, the constraints are dropped w/ it.
