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.

Code at http://www.sommarskog.se/arrays-in-sql.html#iter-list-of-integers.
The rest of the article provides more discussion about this kind of problem.
