Java MySQLSyntaxErrorException

您好，我目前正在开发一个应用程序来维护某工厂的库存，我在将订单插入数据库时遇到问题。。我试着自己解决这个问题，但我做不到，所以如果有人能帮上忙，我很高兴

这是我的错误

我的代码是

for (int i = 0; i < jTable1.getRowCount(); i++) {
            String $Name = "", $Color = "", $Leather = "", $s38 = "", $s39 = "", $s40 = "", $s41 = "", $s42 = "", $s43 = "", $s44 = "", $s45 = "", $s46 = "", Total = "", ItemId = "";
            $Name += jTable1.getValueAt(i, 0)+"";
            $Color += jTable1.getValueAt(i, 1)+"";
            $Leather += jTable1.getValueAt(i, 2)+"";
            $s38 += jTable1.getValueAt(i, 3)+"";
            $s39 += jTable1.getValueAt(i, 4)+"";
            $s40 += jTable1.getValueAt(i, 5)+"";
            $s41 += jTable1.getValueAt(i, 6)+"";
            $s42 += jTable1.getValueAt(i, 7)+"";
            $s43 += jTable1.getValueAt(i, 8)+"";
            $s44 += jTable1.getValueAt(i, 9)+"";

            $s45 += jTable1.getValueAt(i, 10)+"";
            $s46 += jTable1.getValueAt(i, 11)+"";
            Total += jTable1.getValueAt(i, 12)+"";
            ItemId += jTable1.getValueAt(i, 13)+"";
            DB.Save_Update_Delete("insert into order (Add_Order_PID,Customer_idCustomer,Items_idItems,User_idUser,Color,Leather,s38,s39,s40,s41,s42,s43,s44,s45,s46,Total) values ('"+pid+"','"+Integer.parseInt(customerID.getText())+"','"+Integer.parseInt(ItemId)+"','"+Integer.parseInt(UserID.getText())+"','"+$Color+"','"+$Leather+"','"+$s38+"','"+$s39+"','"+$s40+"','"+$s41+"','"+$s42+"','"+$s43+"','"+$s44+"','"+$s45+"','"+$s46+"','"+Total+"')");
        }

for（int i=0；i

您正在用引号（“”）插入int值

---

更好地使用它，从这里检查Add\u Order\u PID是否为整数。如果它是整数，不要用双引号括起来

对于任何数字数据类型，不要在双引号中加上

最好使用PreparedStatement进行插入

insert into order (Add_Order_PID,Customer_idCustomer,Items_idItems,User_idUser,Color,Leather,s38,s‌​39,s40,s41,s42,s43,s44,s45,s46,Total) values ('8','1','2','1','Black','Leather 1','2','0','0','0','0','0','0','0','0','2')

直接在mysql控制台中尝试sql语句。它将给你更多关于真正问题是什么的信息。可能您违反了某些外键。

请使用prepared语句详细说明“使用prepared语句”：prepared语句更有效，并且不会受到SQL注入攻击，而串联SQL字符串（正如您所使用的）则不会。@FrankSchmitt是PreparedStatement在where子句下添加条件的任意方式，或者我需要先确定所有条件，然后在一次过中做一个准备好的声明。很抱歉，这是离题的。@GauravGupta我建议你就此单独问一个问题；对于这个问题有一些解决方案（即使条件的数量不同，例如，对客户机代码未提供的绑定变量使用虚拟或子句），但有些解决方案是特定于RDBMS的（例如，在Oracle中使用SYS_上下文）。请添加表结构好吗？不确定这是否是问题所在，但通常SQL server会足够聪明，可以为int输入字符串值（单引号）。@Shashi我知道，我使用Oracle和MSSQL进行了测试，但将单引号括在整数周围没有问题。但是对于MYSQL，我在阅读时注意到上面的OP是比较带引号的整数的，所以我想它至少适用于他的MYSQL版本。@JqueryLearner我也尝试了准备好的语句，但给出了相同的结果error@user3615913编辑你的问题，显示您的架构并更新JDBC代码。同时检查每个字段是否有任何值或其空值。您的一些字段不是空值，因此如果插入空值，也会导致问题。我删除了双引号，但他/我收到了相同的错误。除此之外，当我删除双引号时，它看起来像一个字符串。我也尝试了准备好的语句，但它给出了相同的错误。请提供表结构。。使用pastebin.com并提供url。。最好使用表结构更新问题
