mysql
I have:
+----+------+------+
| id | A | B |
+----+------+------+
| 1 | 1 | 1 | <
| 2 | 1 | 2 | <
| 3 | 2 | 2 |
| 4 | 2 | 3 |
| 5 | 3 | 1 | <
| 6 | 3 | 2 | <
| 7 | 4 | 4 |
| 8 | 4 | 5 |
+----+------+------+
I need to select the entries that have the same set of B values for their common A value. So, in this case, I need ids 1, 2 and 5, 6 because in those cases the sequence of B values is 1, 2.
Is this possible?
Thanks!
