OpenQuery and passing variables

Anyone,

Is this possible?

I am connecting to a TeraData server via MS SQL 8.0 using the OpenQuery
statement. I need to pass a list of ever-changing deal numbers My
list of numbers are stored as a table on MS SQL.

So what I want is this

Select * from OpenQuery(TeraSrvr, "
Select Col1
, Col2
, Col3
>From Teradata_Table_1
Where Deal_no in (Select Deal_no from SQLTable)
")

Now I know that wont work, but How can I pass 184 Deal Numbers from my
SQL server to this query before it is sent to the Teradata server to be
done? Do I have to keep re-doing an in statement each month?

Anyone can help?

To do it with OPENQUERY you would have to use dynamic SQL to build
the SQL statement, and also to execute the OPENQUERY thing, as
OPENQUERY does not take parameters of any kind of whatsoever.

But cannot you not use a linked server instead:

SELECT t.*
FROM TeraSrvr.db.catalog.Teradata_Table_1 t
WHERE t.Deal_no in (Select s.Deal_no from SQLTable s)

with how to do this in Dynamic SQL. I can't find how to get a list of
my numbers into a Var so I can pass them on and use them in the
openquery statement.

Thanks again

Alas, in SQL 2000 the only safe way is to run a loop over the table.
There are some shortcuts, but they unrely undefined behaviour, so I
advise against such use.

For dynamic SQL in general, I have a longer article on the topic on
my web site: http://www.sommarskog.se/dynamic_sql.html.
