Tuesday Tidbit – JOIN on multiple fields

by gorthx

I use this so rarely I have a hard time remembering the syntax; I always try to use a comma instead of AND. Which, of course, throws an error.

Looks like this:
SELECT [stuff]
FROM table1 t1
JOIN table2 t2 ON
(t1.field1 = t2.field1 AND t1.field2 = t2.field2);
