| 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: |
