Question

我正在尝试在SQL中使用我的更新命令。每次我尝试更新记录时，我都会在字符串后面得到以下错误的未闭合引号。这是我的代码：

String^ connectionString = L"**********"; 
SqlConnection^ myCon = gcnew SqlConnection(connectionString);

SqlCommand^ myCommand = gcnew SqlCommand("UPDATE ******* SET Customer_Name = '" + this -> txtName -> Text + "', Customer_Address = '" + this -> txtPhone -> Text + "', Customer_City = '" + this -> txtCity -> Text + "', Customer_State = '" + this -> txtState -> Text + "', Customer_Zip = '" + this -> txtZip -> Text + "', Customer_Phone = '" + this -> txtPhone -> Text + "', Customer_Email = '" + this -> txtEmail -> Text + "' where Customer_Name = '" + this -> txtName -> Text + ",);", myCon);
SqlDataReader^ myReader;

try {
       myCon -> Open();
       myReader = myCommand -> ExecuteReader();
       MessageBox::Show("Updated!!");
}
catch (Exception^ ex) {
    MessageBox::Show(ex->Message);
}

我不确定如何解决此错误。任何帮助都会很棒。

您的查询中确实有错误。 where部分缺少引号。

而不是

"' where Customer_Name = '" + this -> txtName -> Text + "**,);**"

你应该写

"' where Customer_Name = '" + this -> txtName -> Text + "**';**"

字符串sql server
