Hi, I am using the following code to get the column names of my postgres table but it fails. My database name is "employee" and table name is "employee". Postgres version : 9.3 jdbc driver version : 9.3 public class DBTest { public static void main(String[] args) throws Throwable { Connection conn = getDBConnection(); DatabaseMetaData metaData = conn.getMetaData(); ResultSet resultSet = metaData.getColumns(null, "employee", "employee", null); if (!resultSet.next()) System.out.println("No result set Entries!!"); while (resultSet.next()) { System.out.println(resultSet.getString("COLUMN_NAME")); } conn.close(); } public static Connection getDBConnection() { Connection conn = null; try { Class.forName("org.postgresql.Driver"); conn = DriverManager.getConnection("jdbc:postgresql://sampel.db:5432/data_gen", "postgres", "postgres"); } catch (Throwable th) { th.printStackTrace(); } return conn; } any ideas??
