SQL Checking for Temp Table

I am getting inconsisten results from my SQL code that checks if the #TempTable exists before adding query records into it.

if OBJECT_ID(N'tempdb..#RollTest') is not null
		Begin
			truncate table #RollTest
		End
	Else
		Begin
			Create table #RollTest(
			   [AccountNumber] varchar (15)
				,[CAmt] numeric(15,2)
				,[VisitID] varchar (15),
				Typ varchar(5)
				);
		End

Open in new window


If the table does not exost in memory I get the error that object does not exist.  I want the code to create the table when it does not exist yet.

What is the proper syntax?

Thanks

Glen

My solution has a flaw. If you modify your table code, it will not apply those changes because if the temp table exist "IF OBJECT_ID('#RollTest') IS NULL " will return false thus bypassing the create t-sql. So, it should be revised to:

use tempdb;
go
IF OBJECT_ID('#RollTest') Not IS NULL
-- Begin    --<-- Begin/end is optional
   Drop Table #RollTest;
-- End        
Create table #RollTest(
[AccountNumber] varchar (15)
, [CAmt] numeric(15,2)
, [VisitID] varchar (15)
, Typ varchar(5));
