Actually might be a simple question:
Given 2 tables:
table1: A,B,C (A1,B1,28471), (A1,B2,01244), (A2,B1,1283a), (A2,B2,82r7e); table2: A,B,D,E,F,G (A1,B1,18,1,6,8), (A2,B2,18,2,3,0), (A3,B1,18,7,1,4), (A4,B2,18,1,9,6);
Will the following statement result in a the following result given the example tables:
SELECT E,F,G FROM table2 WHERE (A,B) IN (SELECT A,B FROM table1)
E F G (1,6,8), -- (A1,B1) (2,3,0); -- (A2,B2)
Can someone confirm this is a valid method to select based on tuples?
asking as the most likely next step is to UPDATE the E field by adding +5 for matching results
