IDENTITY_VAL_LOCAL() returned value is modified incorrectly by a multi-row
INSERT statement.
--------------------------------------------------------------------------------------------
Key: DERBY-1554
URL: http://issues.apache.org/jira/browse/DERBY-1554
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.2.0.0
Reporter: Daniel John Debrunner
Changes made in DERBY-353 break the documented behaviour of
IDENTITY_VAL_LOCAL(). Now the returned value is modified when a multi-row
insert is performed.
IDENTITY_VAL_LOCAL() should not be updated when this occurs.
For this script the last value returned should be 2 (as in 10.1) but in 10.2 is
4
create table ta (a int, b int generated always as identity);
insert into ta(a) values 100;
values IDENTITY_VAL_LOCAL();
insert into ta(a) values 200;
values IDENTITY_VAL_LOCAL();
insert into ta(a) values 300,400;
values IDENTITY_VAL_LOCAL();
