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