> Key: DERBY-1355
> URL: https://issues.apache.org/jira/browse/DERBY-1355
> Project: Derby
> Issue Type: Bug
> Components: Network Client
> Affects Versions: 10.1.2.1
> Environment: Windows XP
> Reporter: Piet Blok
> Assigned To: Mayuresh Nirhali

> With ClientDriver, resultSet.getMetaData().isAutoIncrement(column) always returns false.
> EmbeddedDriver correctly returns the true value (true or false)
> The following code demonstrates the problem:
