Derby/JavaDB を使用して、テスト目的でインメモリ データベースを作成したいと考えています。Java DB Developer's Guide: Using in-memory databases を読みderby.jar、「ビルドパス」で JDK7 からのこのコードでテストしました:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class DBTest {
    public static void main(String[] args) {
        final String sql = "DECLARE GLOBAL TEMPORARY TABLE memtable "+
                            "(id int, name varchar(10))";
        final String connURL = "jdbc:derby:memory:memdatabase;create=true";

        try(Connection conn = DriverManager.getConnection(connURL);
            PreparedStatement ps = conn.prepareStatement(sql);) {

            boolean success = ps.execute();
            System.out.println("Memory database created: " + success);

        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

しかし、アプリケーションを実行すると、次のエラーが発生します。

Derby/JavaDB でメモリ内データベース テーブルを作成するにはどうすればよいですか?

最後に NOT LOGGED が欠けていると思います：

  declare global temporary table SESSION.t1(c11 int) not logged;
