# 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:
