# title: Add RESTART [WITH] clause for alter identity columns
|
|
# decription:
|
|
# ::: NB :::
|
|
# Behaviour of FB 4.x was changed since 06-aug-2020 when core-6084 was fixed:
|
|
# now FB 4.x will assign to ID column values which less than FB 3.x for 1.
|
|
# For this reason it was changed avoid check for concrete values.
|
|
# Rather, it is enough to verify only difference between max and min ID.
|
|
#
|
|
# Checked on 4.0.0.2164, 3.0.7.33356.
