Filter Expression

[coosa]

Hi

I have some data that need to be filtered based on a SET of Id's.
If it's about a single ID, then i would pass it as a parameter in a
stored procedure and use it within the the WHERE Clause, but here those
ID's are determined in run time and I can't simply create a a stored
procedure for an unknown amount of ID's.
I looked into the SQL Server 8.0 Manual but had no examples how to use
the Function Filter.
Generaly, how can filter some records based on a set of ID's?

Best regards

FROM tbl t
JOIN iter_intlist_to_tbl(@list_of_ids, DEFAULT) f ON t.id = f.number

iter_intlist_to_tbl is table-valued function that unpacks a space-
separared list of integers into table which you then join with.

The rest of the article provides more discussion about this kind of problem.
