Question

我通过jaggery脚本为sql查询发送了4个值。这是sql查询：

SELECT full_name , sum( amount ) AS total 
    FROM hourlyusage , user
    WHERE   DAY = DATE( DATE_SUB( NOW( ) , INTERVAL ? HOUR ) ) 
            AND HOUR BETWEEN HOUR( DATE_SUB( NOW( ) , INTERVAL ? HOUR ) ) 
            AND HOUR( DATE_SUB( NOW( ) , INTERVAL 1 HOUR ) )
            AND hourlyusage.userIp = user.ip_address 
            AND (user.full_name LIKE '%?%' OR user.user_name LIKE '%?%')  GROUP BY full_name

但它给出了这样的例外。嵌套异常： - java.sql.SQLException：参数索引超出范围（3>参数个数，即2）。

这是什么原因？

SELECT full_name , sum( amount ) AS total 
    FROM hourlyusage , user
    WHERE   DAY = DATE( DATE_SUB( NOW( ) , INTERVAL ? HOUR ) ) 
            AND HOUR BETWEEN HOUR( DATE_SUB( NOW( ) , INTERVAL ? HOUR ) ) 
            AND HOUR( DATE_SUB( NOW( ) , INTERVAL 1 HOUR ) )
            AND hourlyusage.userIp = user.ip_address 
            AND (user.full_name LIKE ? OR user.user_name LIKE ?)  GROUP BY full_name

你不能在sql查询中使用通配符，所以尝试从sql中删除通配符并将其添加到值中。正如你在sql中所做的那样'％？％'表示你需要全局匹配。你的值不是在sql查询中。

SQL异常参数索引超出范围
