Being just the server admin I'll forward this thought on to the dev's
for consideration.

Have you considered joining two tables, one of which is a UNION ALL sum
of the identifiers?

For example:

Select *
>From MyTable
Inner join (
Select 12345 as MyColumn
Union all select 45678
Union all select 7890
) as MyCriteria on MyTable.MyColumn = MyCriteria.MyColumn;
