Stored procedure or function expects parameter which was not supplied

Question

I am trying to insert data into a SQL Server database by calling a stored procedure, but I am getting the error

*Procedure or function \'Insertion\'

Answer 1

You need to use this:

cmd.Parameters.AddWithValue("@Emp_no", @Emp_no);
cmd.Parameters.AddWithValue("@Emp_name", @Emp_name);
cmd.Parameters.AddWithValue("@phone", @phone);
cmd.Parameters.AddWithValue("@Email", @Email);
cmd.Parameters.AddWithValue("@Password", @Password);
cmd.Parameters.AddWithValue("@Gender", @Gender);
cmd.Parameters.AddWithValue("@Dob", @Dob);
cmd.Parameters.AddWithValue("@Address", @Address);
cmd.Parameters.AddWithValue("@Designation", @Designation);
cmd.Parameters.AddWithValue("@Experience", @Experience);
cmd.Parameters.AddWithValue("@Salary", @Salary);
cmd.Parameters.AddWithValue("@Doj", @Doj);

Otherwise, it will throw that exception for each of the parameters.
