50 # | |
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: | |
