System.Data.SqlClient.SqlException (0x80131904): ')' 附近的语法不正确

Question

我一直在尝试调试一段代码，但到目前为止我一直没有成功。

我不断收到这个错误

System.Data.SqlClient.SqlException (0x80131904): ')' 附近的语法不正确

我似乎看不出错误在哪里。

代码如下，查看了该站点上的各种答案并查看了示例。情况是我正在编写一个访问数据库并能够将数据添加和保存到该数据库的程序。它位于服务器上 - 尽管这是在我的笔记本电脑上。

我已经编写、重写和复制了连接字符串，以确保其中没有错误，甚至将字符串的副本放入 word 中，并将其与编码本身中的字符串进行比较，但无济于事。

Answer 1

在您的列列表和VALUES 部分的结尾) 之前有一个额外的 逗号：

SqlCommand cmd = new SqlCommand("INSERT INTO ClientTable(Id, ClientName, CompanyName, CompanyAddress1, CompanyAddress2, CompanyAddress3, CompanyTown, CompanyPostCode, TelephoneNumber, CompanyEMail, 

 CompanyNotes,) 
            ****

VALUES(@parameter1, @parameter2, @parameter3, @parameter4, @parameter5, @parameter6, @parameter7, @parameter8, @parameter9, @parameter10, 

 @parameter11,)", con);
            ****

删除它，你应该没问题
