| 51 # As shown by ticket #3346 above (see also ticket #3298) it is important |
| 52 # that a subquery in the result-set be able to look up through multiple |
| 53 # FROM levels in order to view tables in the FROM clause at the top level. |
| 54 # |
| 55 # But ticket #3530 shows us that a subquery in the FROM clause should not |
| 56 # be able to look up to higher levels: |
