Question

Hey so I have a Junction table linking two unrelated tables. Both the tables have ID‘s. I need to select the ID from each table using WHERE with different values, for example this is how I see it:

INSERT INTO c (aID, bID)
VALUES (SELECT a.ID WHERE a.Name="Me", SELECT b.ID WHERE b.Class="Math");

All the examples I’ve seen use a join statement but the two tables have a common value, in this case they don’t.

Answer 1

Try this query:

     INSERT INTO C (aID, bID) 
     SELECT A.ID, B.ID 
     FROM A, B 
     WHERE A.Name='Me'
     AND B.Class='Math';
