Java java.sql.SQLException：准备语句中的列索引无效

时间：2013-01-23 11:21:47

标签： java oracle jdbc sqlexception

我的代码在下面根据用户输入查询数据库中的一组行。我已经尝试并测试了SQL Developer中的查询，它可以很好地返回正确的行。输入的示例是：2013-01-22

但由于某种原因，在java内部我收到了这个错误：

java.sql.SQLException: Invalid column index

控制台指示它在此处开火：

preparedStatement.setString(1, to);

完整的连接代码：

ResultSet rs = null;
        PreparedStatement preparedStatement = null;
        try {
            String strQuery =
                    "SELECT homes.home_id, homes.title, homes.description, homes.living_room_count, homes.bedroom_count, homes.bathroom_count, homes.price, homes.sqft,"
                    + " listagg(features.feature_name, '\n') WITHIN GROUP(ORDER BY features.feature_name) features, home_type.type_name"
                    + " FROM homes"
                    + " INNER JOIN bookings ON bookings.home_id <> homes.home_id"
                    + " INNER JOIN home_feature ON homes.home_id = home_feature.home_id"
                    + " INNER JOIN home_type ON home_type.type_code = homes.type_code"
                    + " INNER JOIN features ON home_feature.feature_id = features.feature_id"
                    + " WHERE bookings.booking_end < date '?'"
                    + " OR bookings.booking_start > date '?'"
                    + " GROUP BY homes.home_id, homes.title, homes.description, homes.living_room_count, homes.bedroom_count, homes.bathroom_count, homes.price, homes.sqft, home_type.type_name";

            preparedStatement = conn.prepareStatement(strQuery);//prepare the statement
            preparedStatement.setString(1, to);//insert
            preparedStatement.setString(2, from);//insert
            rs = preparedStatement.executeQuery();//execute query

我不太清楚为什么错误会被抛出，因为查询工作正常是SQL开发人员。我正在使用Oracle

编辑：

结果集在同一方法中读入。然后传回homes对象：

HomeList homes = new HomeList();
homes = new HomeList(rs);

构造函数如下所示：

public HomeList(ResultSet rs) {
    this();
    try {
        while (rs.next()) {
               list.add(new Home(rs.getInt(1),   
                                 rs.getString(2),
                                 rs.getString(3),   
                                 rs.getInt(4),
                                 rs.getInt(5),
                                 rs.getInt(6),
                                 rs.getInt(7),
                                 rs.getInt(8),
                                 rs.getString(9),
                                 rs.getString(10)
                                     ));
        }//end while
    } catch (SQLException e) {
        e.printStackTrace();
    }//end try
}

3 个答案:

答案 0 :(得分：30)

查询字符串中的所有位置，通配符应为?而不是'?'。这应该可以解决问题。

编辑：

要添加，您需要将date '?'更改为to_date(?, 'yyyy-mm-dd')。请尝试一下，让我知道。

答案 1 :(得分：2)

正如@TechSpellBound建议删除周围的报价？迹象。然后在连接字符串的每一行末尾添加一个空格字符。否则整个查询将作为示例发送（仅使用其中的一部分作为示例）：.... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

?和OR需要用空格字符分隔。在查询字符串中的任何需要的位置执行。

答案 2 :(得分：0)

在date '?'中，'?'是一个值为?的文字字符串，而不是参数占位符，因此您的查询没有任何参数。 date是从（文字）字符串到目前为止的简写。您需要将date '?'替换为?以实际拥有参数。

此外，如果您知道这是日期，请使用setDate(..)而不是setString(..)来设置参数。
