如何在Oracle SQL的Select语句中重命名表列？

上面显示的是结果。我得到正确的数据，只需要更改列名。问题是我正在尝试重命名表中的列。我已经尝试过以下错误-java.sql.SQLSyntaxErrorException：ORA-00923：找不到期望的FROM关键字：

"SELECT to_char(logdate,'dd-MON-yy') AS DATE, adj_login_time AS LOGIN, adj_logout_time AS LOGOUT, adj_lunch_in AS LUNCHIN, adj_lunch_out AS LUNCHOUT, round(logduration,2) AS LOGDURATION " +
                        "FROM employee_time_log " +
                        "WHERE employee_id_number = " +userInputIdNumber +" AND ROWNUM <= 10" +
                        "ORDER BY logdate DESC");
AND
"SELECT to_char(logdate,'dd-MON-yy') AS 'Log Date', adj_login_time AS 'Log In Time', adj_logout_time AS 'Log Out Time', adj_lunch_in AS 'Lunch In', adj_lunch_out AS 'Lunch Out', round(logduration,2) AS 'Log Duration' " +
                        "FROM employee_time_log " +
                        "WHERE employee_id_number = " +userInputIdNumber +" AND ROWNUM <= 10" +
                        "ORDER BY logdate DESC");

我正在使用NetBeans IDE并在JAVA中进行编码。我尝试了上述其他几种方法，但都没有碰到运气。谢谢您的帮助！

private DefaultTableModel weeklyLogTableModel(ResultSet weeklyLogSet) throws SQLException
{
    ResultSetMetaData metaData = weeklyLogSet.getMetaData();

    Vector<String> columnNames = new Vector<String>();
    int columnCount = metaData.getColumnCount();
    for (int column = 1; column <= columnCount; column++)
    {
        columnNames.add(metaData.getColumnName(column));
    }

    Vector<Vector<Object>> data = new Vector<Vector<Object>>();
    while (weeklyLogSet.next())
    {
        Vector<Object> vector = new Vector<Object>();
        for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++)
        {
            vector.add(weeklyLogSet.getObject(columnIndex));
        }
        data.add(vector);
    }
    return new DefaultTableModel(data, columnNames);
}

private void userDashboard(int userInputIdNumber) 
{
    jPanel1.setVisible(false);
    jPanel2.setVisible(true);
    jPanel3.setVisible(false);
    jPanel4.setVisible(false);
    try
    {
             //Getting Information FROM EMPLOYEE_TIME_LOG for Weekly Log
            Statement weeklyLogstmt = dbConn.createStatement();
            ResultSet weeklyLogSet = weeklyLogstmt.executeQuery (
                    "SELECT to_char(logdate,'dd-MON-yy') AS Date, adj_login_time, adj_logout_time, adj_lunch_in, adj_lunch_out, round(logduration,2) " +
                    "FROM employee_time_log " +
                    "WHERE employee_id_number = " +userInputIdNumber +" AND ROWNUM <= 10" +
                    "ORDER BY logdate DESC");

            jTable3.setModel((TableModel)weeklyLogTableModel(weeklyLogSet));
}
