WHERE fieldname IN (SELECT fieldname FROM #temptable)?

Please can someone help me here.  I am sure this is quite obvious to most SQL people but I cannot work out what is going wrong!!!!

I have a T-SQL script that creates a temporary table...

CREATE TABLE #TempContainers
(
DRA_Container varchar(255)
)

It then uses an INSERT command to fill it with multiple records.

Now, the following statement works as expected...

SELECT DRA_Container FROM #TempContainers

This gives me two records (PRDGB and OCDGB).

However, when I issue the following command...

SELECT * FROM DRA_Totals WHERE DRA_Container IN (SELECT DRA_Container FROM #TempContainers)

I only get the records from DRA_Totals with one of the DRA_Containers in #TempContainers and not the other one.  Incidentally, if I don't use a SELECT in the brackets but specify the values (e.g. IN ('value1','value2')), it picks up both correctly.

Is this a problem with temporary tables or something else I have overlooked?  Tried EXISTS too but don't think I fully understand how to get what I need :-)

Many thanks,
Tony

what is the data type of DRA_Container in DRA_Totals?

and there is no reason why it would only take 1 of the values from a temporary table.
there must be indeed something else that gets overlooked...

your code looks 100% fine.

question: where is the < appearing in the output if you do this:
SELECT DRA_Container + '<' FROM #TempContainers

could you "feed" me with a script to create the table you query, how you "fill" the temporary table?
so I could try to reproduce the problem?

Hi Angellll.  I have now solved this.  Appears it was a datatype issue - when populating the lookup table with the INSERT.  Should have spotted it so sorry for wasting your time.  The points are yours though for taking time to respond, and so quickly too.  Thanks again.  Thought I was going mad!!!
