Here is the Example.
I have two tables Manager and Employee each has different Empids and Salaries so i want to get the Maximum sal of the Two tables.for that i have used #temptables.

select salary into #temptbks from Empsal Union select salary from Managers;select max(salary)as salary from #temptbks;
drop table #temptbks.As soon as temptable is created U should delete so that u can use that same table if the Original table has been Updated.The #temptable will be available in that database itself.In sql-server.If u want this query in asp.net than go for Stored procedure.

Hi Mike,

The objectid of temporary table can be viewed by this query:

select OBJECT_ID(‘tempdb.dbo.#tmp_mwj’)

Well when I try this I get a NULL value returned.

select my_id, my_name
into #tmp_mwj
from dbo.my_table

(creates table)

select OBJECT_ID(‘dbo.#tmp_mwj’)
(returns null)

SELECT 1
FROM dbo.sysobjects
WHERE ID = OBJECT_ID(‘dbo.#tmp_mwj’)

Thanks! This was a great place to get a working solution for us. I modified it slightly:
Select
1
FROM
tempdb.dbo.sysobjects (nolock)
WHERE
ID = OBJECT_ID(N’tempdb.dbo.#batch’) and
[Type] = ‘U’

Our deployment team doesn’t like “Select *” for any reason, also added a (nolock) hint and limited it User ‘U’ object types only.

“i tired using it
i get sysntax error
Incorrect syntax near ‘)’ ” – SVK

I suspect that this is because the character ’ (single quote) is invalid, it should be ‘ (apostrophe) instead.

What I suspect has happened is that either the database for this website is converting apostrophes to single quote or the developer of the query pasted their query into MS Word which then assumed that the character should be a single quote and converted it.

Solution: Try replacing all single quote characters to apostrophes. I did that and it works fine for me.

Below is how you can check and delete temp tables.

IF EXISTS
(
SELECT *
FROM tempdb.dbo.sysobjects
WHERE ID = OBJECT_ID(N’tempdb..#MyTempTable’)
)
BEGIN
DROP TABLE #MyTempTable
END
