Using tuples in SQL “IN” clause

Question

I have a table containing the fields group_id and group_type and I want to query the table for all the records having any tuple (group id, group type) from

Answer 1

You can use a common table expression to pretend that these tuples are in another table:

;WITH Tuples as (
     select '1234-567' as group_id, 2 as group_type union all
     select '4321-765', 3 union all
     select '1111-222', 5
)
SELECT * /* TODO - Pick appropriate columns */
from mytable m where exists (
   select * from Tuples t
   where m.group_id = t.group_id and m.group_type = t.group_type)
