Description

With ClientDriver, resultSet.getMetaData().isAutoIncrement(column) always returns false.

EmbeddedDriver correctly returns the true value (true or false)

The following code demonstrates the problem:
===================================================================================
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;

import org.apache.derby.jdbc.ClientDriver;
import org.apache.derby.jdbc.EmbeddedDriver;

public class TestAutoIncrement {
private static final String URL_EMBEDDED = "jdbc:derby:EmbeddedTestBase;";

private static final String URL_CLIENT = "jdbc:derby://localhost:1527/ClientTestBase;";

public TestAutoIncrement()

{ super(); }

public static void main(String[] args) throws SQLException

{ System.out.println(new ClientDriver().getClass().getName() + " registered"); System.out.println(new EmbeddedDriver().getClass().getName() + " registered"); new TestAutoIncrement().test(); }

private void test() throws SQLException {
if (test(URL_EMBEDDED) != test(URL_CLIENT))

{ System.out.println("Embedded and client driver behave differently for isAutoIncrement()."); }

else

{ System.out.println("Embedded and client driver behave the same for isAutoIncrement()."); }

}

private boolean test(String url) throws SQLException {
boolean ai = false;
Connection connection = DriverManager.getConnection(url
+ "create=true;");
Statement statement = connection.createStatement();
statement
.execute("CREATE TABLE TEST_TABEL ("
+ "ID INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),"
+ "VALUE INTEGER NOT NULL, PRIMARY KEY (ID))");
statement.execute("INSERT INTO TEST_TABEL (VALUE) VALUES(1)");
ResultSet resultSet = statement
.executeQuery("SELECT * FROM TEST_TABEL");
ResultSetMetaData meta = resultSet.getMetaData();
ai = meta.isAutoIncrement(1);
System.out.println("For " + url + " " + meta.getColumnName(1)
+ " isAutoIncrement: " + ai);
connection.close();
try

{ DriverManager.getConnection(url + "shutdown=true;"); }

catch (SQLException e)

{ System.out.println(e.getMessage()); }

return ai;
}

}
===================================================================================
The output I receive from the above program is:

org.apache.derby.jdbc.ClientDriver registered
org.apache.derby.jdbc.EmbeddedDriver registered
For jdbc:derby:EmbeddedTestBase; ID isAutoIncrement: true
Database 'EmbeddedTestBase' shutdown.
For jdbc:derby://localhost:1527/ClientTestBase; ID isAutoIncrement: false
DERBY SQL error: SQLCODE: -1, SQLSTATE: 08006, SQLERRMC: Database
'ClientTestBase' shutdown.
Embedded and client driver behave differently for isAutoIncrement().
