DROP TABLE fails for temp table

I have a client application that creates a temp table, the performs a bulk insert into the temp table, then executes some SQL using the table before deleting it.

Pseudo-code:

open connection
begin transaction
CREATE TABLE #Temp ([Id] int NOT NULL)
bulk insert 500 rows into #Temp
UPDATE [OtherTable] SET [Status]=0 WHERE [Id] IN (SELECT [Id] FROM #Temp) AND [Group]=1
DELETE FROM #Temp WHERE [Id] IN (SELECT [Id] FROM [OtherTable] WHERE [Group]=1)
INSERT INTO [OtherTable] ([Group], [Id]) SELECT 1 as [Group], [DocIden] FROM #Temp

DROP TABLE #Temp
COMMIT TRANSACTION
CLOSE CONNECTION

This is failing with an error on the DROP statement:

Cannot drop the table '#Temp', because it does not exist or you do not have permission.

I can't imagine how this failure could occur without so开发者_Python百科mething else going on first, but I don't see any other failures occurring before this.

Is there anything that I'm missing that could be causing this to happen?

possibly something is happening in the session in between?

Try checking for the existence of the table before it's dropped:

IF object_id('tempdb..#Temp') is not null
BEGIN
   DROP TABLE #Temp
END

I've tested this on SQL Server 2005, and you can drop a temporary table in the transaction that created it:

begin transaction
create table #temp (id int)
drop table #temp
commit transaction

Which version of SQL Server are you using?

You might reconsider why you are dropping the temp table at all. A local temporary table is automatically deleted when the connection ends. There's usually no need to drop it explicitly.

A global temporary table starts with a double hash (f.e. ##MyTable.) But even a global temp table is automatically deleted when no connection refers to it.

I think you aren't creating the table at all, because the statement

CREATE TABLE #Temp ([Id] AS int)

is incorrect. Please, write it as

CREATE TABLE #Temp ([Id] int)

and see if it works.

BEGIN TRAN

IF object_id('DATABASE_NAME..#TABLE_NAME') is not null
BEGIN
   DROP TABLE #TABLE_NAME
END

COMMIT TRAN

Note:Please enter your table name where TABLE_NAME and database name where it says DATABASE_NAME
