Hi,
I have a table login in sql it contains lots of fields(for example fname,lname,Password,address,Username etc). I need to insert some data only to the table(Username and Password). I use the code in C#

C#

SqlCommand cmd = new SqlCommand("insert into login values(@UserName)", con);
          cmd.Parameters.AddWithValue("@UserName", txtUserName.Text);
          cmd.Parameters.AddWithValue("@Password", txtPassword.Text);

on clicking submit button it shows an error message:
"Column name or number of supplied values does not match table definition"
Please correct the problem.

IF You want to insert specific columns data only then you have to write it also in query like that...

C#

SqlCommand cmd = new SqlCommand("insert into login (Username, Password) values (@UserName,@Password)", con);
cmd.Parameters.AddWithValue("@UserName", txtUserName.Text);
cmd.Parameters.AddWithValue("@Password", txtPassword.Text);

Solution 1

Your SQL used is incorrect, and should be like the next one:

C#

SqlCommand cmd = new SqlCommand("insert into login (Username, Password) values(@UserName, @Password)", con);
