Hello list, I have two tables:
Table A a_id name 1 a 2 b 3 c Table B b_id a_id flag name 1 2 y x 2 2 n y 3 3 n z How can I find the rows from table A where there is no matching row (joined using a_id as key) in table B where flag is "y"? So in this example I want the entries 1/a and 3/c from table A. 2/b should not be selected because there is a row in table B with a_id = 2 and flag="y". Understandable? It seems quite impossible to me, but I cannot figure out a reason why it is impossible, either.
