在来自另一个表的表中插入数据[关闭]答案

【问题描述】：

我这里有这个查询：

rs = st.executeQuery("SELECT holderName,COUNT(holderName) as total, SUM(is_late) as total_late FROM (SELECT *,timestampdiff(minute, t1.startTime, t.IOTime) as is_late FROM (SELECT holderName, IODate, MIN(IOTime) as IOTime FROM tbl_records where IOStatus='Entry'AND IODate BETWEEN'"+from+"'AND'"+to+"' GROUP BY holderName, IODate) t JOIN tbl_emp t1 ON t.holderName = t1.name HAVING is_late > 0) AS t2 GROUP BY holderName  ORDER BY holderName, IODate");

这将返回 3 个值，我希望它把它放在另一个表中。

我试过这个：

st.executeUpdate("insert into tbl_temp values(null,name,total,total_late) SELECT holderName,COUNT(holderName) as total, SUM(is_late) as total_late FROM (SELECT *,timestampdiff(minute, t1.startTime, t.IOTime) as is_late FROM (SELECT holderName, IODate, MIN(IOTime) as IOTime FROM tbl_records where IOStatus='Entry'AND IODate BETWEEN'"+from+"'AND'"+to+"' GROUP BY holderName, IODate) t JOIN tbl_emp t1 ON t.holderName = t1.name HAVING is_late > 0) AS t2 GROUP BY holderName  ORDER BY holderName, IODate");

我在执行插入时出错了！

谢谢！

【问题讨论】：

insert中的null是自动递增的
希望您能防止 SQL 注入。这是开放的利用。也只是发布你得到的错误。如果我的怀疑是正确的，您只需要删除值语句中的null，因为您不需要指定自动编号。
您遇到什么错误？您应该尝试使用准备好的语句。从结果集中获取数据并将它们作为参数传递给preparedstatement。关注这个link
已经解决了！不应该放“价值观”谢谢！

【解决方案1】：

如果你把你得到的错误放在上面，那就太好了。我现在可以发现的一个错误是在您的查询语法中，您不能拥有 VALUES，它应该是这样的：

INSERT INTO tbl_temp(name,total,total_late)
SELECT holderName,COUNT(holderName) as tot...
