145   birmingham  156   boise  167   raleigh

i want display locations field1 , field 2 having problem join...

select      a.field1, b.id, b.location, a.field2      table a left outer join         table b b on a.field1 = b.id;

i can see location description field1 - how retrieve location description field2 ???

you need join table b twice:

select      a.field1,      b1.id id1,     b1.location location1,     a.field2,      b2.id id2,      b2.location location2 tablea      left outer join tableb b1 on a.field1 = b1.id     left outer join tableb b2 on a.field2 = b2.id;
