> Key: IGNITE-9989
> URL: https://issues.apache.org/jira/browse/IGNITE-9989
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Pavel Kuznetsov
> Assignee: Pavel Kuznetsov
> Priority: Major
> Labels: jdbc
>
> Jdbc v2 driver has hardcoded values for meta attibutes :
> COLUMN_NAME = _KEY
> KEY_SEQ = 1
> PK_NAME = _KEY
> But this values should be different for different tables.
> how to reproduce:
> 1) connect to the cluser using jdbcv2 driver
> 2) CREATE TABLE TAB (ID LONG, SEC_ID LONG, VAL LONG, PRIMARY KEY(ID, SEC_ID))
> 3) check result of connection.getMetadata().getPrimaryKeys()
