Java java.sql.SQLException：准备语句时的列索引无效答案

【问题标题】：Java java.sql.SQLException: Invalid column index on preparing statementJava java.sql.SQLException：准备语句时的列索引无效
【发布时间】：2013-01-06 20:38:17
【问题描述】：

我下面的代码根据用户输入在数据库中查询一组行。我已经尝试并测试了 SQL Developer 内部的查询，它可以很好地返回正确的行。输入示例是：2013-01-22

但由于 java 内部的某种原因，我收到此错误：

java.sql.SQLException: Invalid column index

控制台表明它正在这里触发：

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

我不太清楚为什么在查询正常时会抛出错误是 SQL 开发人员。我正在使用甲骨文

编辑：

在同一方法中将结果集读入此。然后将 home 对象传回：

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
}

【问题讨论】：

你能贴出你用来访问结果集的代码吗？可能是您尝试选择结果集中不存在的列！

【解决方案1】：

正如@TechSpellBound 建议的那样，删除 ?迹象。然后在连接字符串的每一行末尾添加一个空格字符。否则整个查询将被发送为（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。在查询字符串中任何需要的地方执行。

【讨论】：

AFAIK 速记日期转换仅适用于文字字符串，不适用于参数。此外，他的下一行以空格开头，因此您描述的问题实际上并不存在。
我指的是他的例子，否则他可能会感到困惑。 @TechSpellBound 已经提到了这一点

【解决方案2】：

在查询字符串的任何地方，通配符都应该是?，而不是'?'。这应该可以解决问题。

编辑：

除此之外，您需要将date '?' 更改为to_date(?, 'yyyy-mm-dd')。请尝试并告诉我。

【讨论】：

嗨，感谢您的回复。我尝试删除 '' 但控制台抛出 java.sql.SQLException: ORA-00936: missing expression
您应该在每行的末尾放置空格。
对于 java.sql.SQLException: ORA-0093，参考这个 SO 问题stackoverflow.com/questions/10520881/…
@giorashc：很高兴你发现了这个
啊哈，谢谢你的帮助，那工作。更改为 to_date(?)。谢谢

【解决方案3】：

在date '?' 中，'?' 是具有值? 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）字符串到日期的简写形式。您需要将date '?' 替换为? 才能真正拥有参数。

另外，如果你知道它是一个日期，那么使用setDate(..) 而不是setString(..) 来设置参数。
