# title: RDB$GET_TRANSACTION_CN works different in Super and Classic
|
|
# decription:
|
|
# Confirmed bug on 4.0.0.2411 CS: got null instead of positive number.
|
|
# Checked on intermediate build 4.0.0.2416 (08-apr-2021 09:56) - all OK.
|
|
#
|
|
# NB-1: bug can be reproduced using ISQL but it must be lacunhed with '-n' command switch.
|
|
# NB-2: connection-1 (which finally asks value of rdb$get_transaction_cn(<Tx2>)) must start Tx1
|
|
# *BEFORE* connection-2 will start his Tx2.
