Re: Exception while updating result set - Mailing list pgsql-jdbc

Hi,

The following code generates an exception shown below. Commenting out the refreshRow() call would solve the issue. This exception happens only in driver versions 42.2.13 and above. Is this a bug in the driver?

        ResultSet rs = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE ).executeQuery(sql);
        rs.next();
        rs.updateDate("start_date", Date.valueOf("2020-01-01"));
        rs.updateDate("end_date", Date.valueOf("2020-12-31"));
        rs.updateRow();
        rs.refreshRow();
        rs.updateDate("end_date", Date.valueOf("2020-12-30"));
        rs.updateRow(); // Exception occurs at this line.
