Question

我正在编写此代码，通过从SQL中的2个表派生值，从前端将数据插入到SQL中。我收到了一个错误：

'）'
附近的语法不正确

代码：

try
{
    sqlconn.Open();

    string PersonalDetailsquery = "insert into PersonalDetails(@FirstName,@LastName,@Email,@Phone,@Address)";

    SqlCommand sqlcomm1 = new SqlCommand(PersonalDetailsquery, sqlconn);
    sqlcomm1.Parameters.AddWithValue("@FirstName", txtFirstName.Text);
    sqlcomm1.Parameters.AddWithValue("@LastName", txtLastName.Text);
    sqlcomm1.Parameters.AddWithValue("@Email", txtMailId.Text);
    sqlcomm1.Parameters.AddWithValue("@Phone", txtPhoneNum.Text);
    sqlcomm1.Parameters.AddWithValue("@Address", txtAddress.Text);

    sqlcomm1.ExecuteNonQuery();

    sqlcomm1.Parameters.Clear();
    string LoginDetailsquery = "insert into LoginDetails(@Username, @Password, @ConfirmPassword, @[Hint Q1], @Answer1, @[Hint Q2], @Answer2, @[Hint Q3], @Answer3)";

    SqlCommand sqlcomm2 = new SqlCommand(LoginDetailsquery, sqlconn);
    sqlcomm2.Parameters.AddWithValue("@Username", txtUserName.Text);
    sqlcomm2.Parameters.AddWithValue("@Password", txtPassword.Text);
    sqlcomm2.Parameters.AddWithValue("@ConfirmPassword", txtConfirmPsw.Text);
    sqlcomm2.Parameters.AddWithValue("@[Hint Q1]", ddlHintQ1.SelectedItem.Text);
    sqlcomm2.Parameters.AddWithValue("@Answer1", txtHintQ1.Text);
    sqlcomm2.Parameters.AddWithValue("@[Hint Q2]", ddlHintQ2.SelectedItem.Text);
    sqlcomm2.Parameters.AddWithValue("@Answer2", txtHintQ2.Text);
    sqlcomm2.Parameters.AddWithValue("@[Hint Q3]", ddlHintQ3.SelectedItem.Text);
    sqlcomm2.Parameters.AddWithValue("@Answer3", txtHintQ3.Text);

    sqlcomm2.ExecuteNonQuery();
    Label1.Text = "data Inserted successfully";
}
catch (Exception ex)
{
    Label1.Text = ex.Message;
    Label1.ForeColor = System.Drawing.Color.Red;
}
finally
{
    sqlconn.Close();
}

Answer 1

您的查询必须有VALUES

string PersonalDetailsquery = "insert into PersonalDetails(here your columns) VALUES(@FirstName,@LastName,@Email,@Phone,@Address)";

....

string LoginDetailsquery = "insert into LoginDetails(here your columns) VALUES(@Username,@Password,@ConfirmPassword,@[Hint Q1],@Answer1,@[Hint Q2],@Answer2,@[Hint Q3],@Answer3)";

Answer 2

错误的SQL语法：

试试这个;

class PostList(ArchiveIndexView):
    allow_empty = True
    allow_future = True
    context_object_name = 'post_list'
    date_field = 'pub_date'
    make_object_list = True
    model = Post
    paginate_by = 5
    template_name = 'blog/post_list.html'

OR

INSERT INTO PersonalDetails (column1,column2,column3,...) VALUES (@FirstName,@LastName,@Email,@Phone,@Address);

Answer 3

您的SQL语法错误：

"insert into PersonalDetails VALUES (@FirstName,@LastName,@Email,@Phone,@Address)"

和

"insert into LoginDetails VALUES (@Username,@Password,@ConfirmPassword,@[Hint Q1],@Answer1,@[Hint Q2],@Answer2,@[Hint Q3],@Answer3)"

来自w3schools：

可以用两种形式编写INSERT INTO语句。

第一个表单没有指定数据所在的列名   插入，只有他们的价值观：

INSERT INTO table_name
VALUES (value1,value2,value3,...);

第二种形式指定列名和值插入：

INSERT INTO table_name (column1,column2,column3,...)
VALUES (value1,value2,value3,...);

Answer 4

请再次检查您的查询语句：

你可以尝试：

string PersonalDetailsquery ="INSERT INTO PersonalDetails(FirstName,LastName,Email,Phone,Address)
values('"+txtFirstName.Text+"','"+txtLastName.Text+"','"+txtMailId.Text+"','"+txtPhoneNum.Text+"','"+txtAddress.Text+"')";

'）'附近的语法不正确。从多个表插入数据时
