ISSUE: 4524
|
|
TITLE: Add optional START WITH clause to identity columns
|
|
DESCRIPTION:
|
|
We create table with identity column and use 'START WITH' clause for it.
|
|
Then we add three rows in this table and calculate difference betwee max and min
|
|
values of this identity column. In must be equal 2.
|
|
|
|
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.
