Java java.sql.SQLException : Invalid column index on preparing statement 异常

Question

我下面的代码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。输入的例子是:2013-01-22

但是由于某些原因在 java 中我收到了这个错误:

java.sql.SQLException: Invalid column index

控制台指示它在此处的这一行触发:

preparedStatement.setString(1, to);

完整连接代码:

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

我不太确定为什么会抛出错误，因为查询工作正常是 SQL 开发人员。我正在使用甲骨文

编辑:

结果集在同一方法中读入。然后将 homes 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
}

Answer 1

在查询字符串中的任何地方，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。
