# title: Allow parenthesized query expression for standard-compliance
|

# decription:

# https://github.com/FirebirdSQL/firebird/issues/6740
|

|
|
# NOTE. Queries which do not use `WITH` clause now can be enclosed in parenthesis,
|
|
# but this leads to reduced number of max parts of UNIONed query, from 255 to 128.
|
|
#
|
|
# Checked on 5.0.0.88.
