| 14 | # Queries of the form: |
||
| 15 | # |
||
| 16 | # SELECT group_concat(x) FROM (SELECT * FROM table ORDER BY 1); |
||
| 17 | # |
||
| 18 | # The ORDER BY would be dropped by the query flattener. This used |
||
| 19 | # to not matter because aggregate functions sum(), min(), max(), avg(), |
||
| 20 | # and so forth give the same result regardless of the order of inputs. |
||
| 21 | # But with the addition of the group_concat() function, suddenly the |
||
| 22 | # order does matter. |
