Hi,
I would expect the following to use the index PUBLIC.ID_DATA however it only uses the default primary key index PUBLIC.PRIMARY_KEY_27
create table test(
ID BIGINT PRIMARY KEY AUTO_INCREMENT,
DATA VARCHAR(100)
);
CREATE INDEX ID_DATA ON TEST(ID,DATA);
EXPLAIN PLAN SELECT * FROM TEST WHERE (id>3 AND data = 'SOMETHING')
*****
PLAN
SELECT
TEST.ID,
TEST.DATA
FROM PUBLIC.TEST
/* PUBLIC.PRIMARY_KEY_27: ID > 3 */
WHERE (ID > 3)
AND (DATA = 'SOMETHING')
Is this something I have done wrong or not supported?
The optimiser will use clustered indexes when NOT including the primary key.
I am using the h2-1.3.162.jar
This is very important to fix/workaround.
I am toying with the idea of making another column which is the same as ID and
making clustered indexes on it, then querying on it...
Thanks
From,
Phill
