MYSQL AND OR On Many To Many Table

Question

Kind of a convoluted question but, basically I have a many to many table word_relationships:

+-----+--------+--------+
|  ID | WORD_A | WORD_B |
+--         


        

Answer 1

This should work:

SELECT 
  id 
FROM 
  word_relationships
WHERE 
 (Word_A = w1 AND Word_B = w2)
OR 
 (Word_A = w2 AND Word_B = w1)
