将从数据库中获取数据的Java代码

Question

将在给定图像中获取Reminder1的最后日期的Java代码是什么。

这是我写的，但是它是错误的

StringBuffer sql = new StringBuffer("SELECT * FROM TITAN_PORTAL.Scorecard_Reminder whereStatus='Active'");
        resultSet = stmt.executeQuery(sql.toString());
        while (resultSet.next()) {
            String reminder1 = resultSet.getString("Reminder1.Last_Date");

Answer 1

使用表alias。以便更轻松地检索列名。

StringBuffer sql = new StringBuffer("SELECT * FROM TITAN_PORTAL.Scorecard_Reminder t1 whereStatus='Active'");
resultSet = stmt.executeQuery(sql.toString());
    while (resultSet.next()) {
        String reminder1 = resultSet.getString("t1.Last_Date");
