插入Select&；在java中插入到单个查询中

我正在创建一个计费应用程序。我想在mySQL中同时将相同的数据插入两个不同的表中。谁能告诉我该怎么问。我的任务是首先将数据插入calculationinfo表，然后将相同的数据插入salesinfo表，然后从calculation表中选择all。我正在尝试此操作，但遇到SQL语法错误。 这是我的问题

"Insert into calculationinfo (`date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtotal`) values(?,?,?,?,?,?) INSERT INTO salesinfo (`date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtotal`) SELECT * From calculationinfo"

我正在使用java语言。这是指纹

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'INSERT salesinfo `date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtot' at line 1

使用自动关闭资源，如

try (PreparedStatement stmt = connection.prepareStatement("Insert into calculationinfo (`date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtotal`) values(?,?,?,?,?,?)") {

        //Set Data here     

        stmt.executeUpdate();
    }
    // stmt is auto closed here, even if SQLException is thrown


    try (PreparedStatement stmt = connection.prepareStatement("INSERT INTO salesinfo (`date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtotal`) VALUES (?, ?, ?,?,?,?)");
       //set same data above here
        stmt.executeUpdate();
    }

您需要使用终止符分隔这两个查询

"Insert into calculationinfo"+ 
"(`date`,`prod_name`, `prod_amount`, `total_amount`,`user`, `Gtotal`) "+ 
"values(?,?,?,?,?,?);"+ 
"INSERT INTO salesinfo"+ 
"(`date`,`prod_name`, `prod_amount`,`total_amount`,`user`, `Gtotal`) "+
"values(?,?,?,?,?,?)";

这将帮助您完成查询。我在上面所做的是在以可读模式格式化查询后追加字符串

注意：我将值传递到第二个表的过程与您将值传递到第一个表的过程相同。这也行

---

Insert into table 1从table 2中选择*

会将table 1中的所有行插入table 2中，这会弄乱您的数据。

您在查询中缺少了

into

这个词。我在插入时使用了这两个词，我在哪里遗漏了这个词？根据堆栈跟踪，你在插入salesinfo时漏掉了它，但它还是给了我同样的错误。你应该用

分隔你的语句。现在我得到了这个异常java.sql.SQLException：没有为参数7指定值。首先，我为出于嫉妒而否决这个答案的人感到遗憾。其次，您需要像在Java中通常做的那样，将用户输入传递给
值（UserInput1，UserInput2）
。我不知道java是如何处理数据插入的。
