in a where clause and numeric using WHERE fieldname IN (123, 234, 345)
in a where clause and text using WHERE fieldname IN ('alpha', 'beta', 'gamma')
or if including the specific list is in a table, you can refer to the table & not list them individually in the WHERE clause
SELECT fields
FROM maintable M, filterlist F
WHERE M.commonfield = F.commonfield
Or without a WHERE clause using a join
SELECT fields
FROM maintable M INNER JOIN filterlist F ON m.commonfield = F.commonfield
