SQL Question

Stored procedure or function expects parameter which was not supplied

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' expects parameter '@Emp_no', which was not supplied*


My stored procedure is called
Insertion
. I have checked it thoroughly and no parameters is missing also I have checked it by using a label. The label shows the value but I don't know why I am getting the error.

My code is

try
{
SqlCommand cmd = new SqlCommand();
cmd.Parameters.Clear();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "Insertion";
cmd.Connection = con;

if (rdb_Male.Checked)
{
int @Emp_no = Convert.ToInt32(txtbx_Empno.Text);
string @Emp_name = txtbx_Emp_Name.Text;
double @phone = Convert.ToDouble(txtbx_Phone.Text);
string @Email = txtbx_Email.Text;
string @Password = txtbx_Pwd.Text;
string @Gender = rdb_Male.Text;
DateTime @Dob = Convert.ToDateTime(dob);
string @Address = txtbx_Address.Text;
string @Designation = txtbx_Designation.Text;
string @Qualification = txtbx_Qual.Text;
double @Experience = Convert.ToDouble(txtbx_Exp.Text);
double @Salary = Convert.ToDouble(txtbx_Sal.Text);
DateTime @Doj = Convert.ToDateTime(doj);
}
else if (rdb_Female.Checked)
{
int @Emp_no = Convert.ToInt32(txtbx_Empno.Text);
string @Emp_name = txtbx_Emp_Name.Text;
double @phone = Convert.ToDouble(txtbx_Phone.Text);
string @Email = txtbx_Email.Text;
string @Password = txtbx_Pwd.Text;
string @Gender = rdb_Female.Text;
DateTime @Dob = Convert.ToDateTime(dob);
string @Address = txtbx_Address.Text;
string @Designation = txtbx_Designation.Text;
string @Qualification = txtbx_Qual.Text;
double @Experience = Convert.ToDouble(txtbx_Exp.Text);
double @Salary = Convert.ToDouble(txtbx_Sal.Text);
DateTime @Doj = Convert.ToDateTime(doj);
}

if (con.State==ConnectionState.Closed)
con.Open();

LABEL.Text = txtbx_Empno.Text;

cmd.ExecuteNonQuery();

lbl_Errormsg.Visible = true;
lbl_Errormsg.Text = "Record Inserted Successfully";

con.Close();
}


and the stored procedure is

ALTER PROCEDURE dbo.Insertion
(
@Emp_no int,
@Emp_name varchar(30),
@phone numeric(10,0),
@Email varchar(30),
@Password varchar(10),
@Gender varchar(6),
@Dob date,
@Address varchar(100),
@Designation varchar(20),
@Qualification varchar(20),
@Experience numeric(4,2),
@Salary numeric(10,2),
@Doj date
)
AS
Begin
Insert into Register (Emp_no, Emp_name, phone, Email, Password, Gender, Dob, Address, Designation, Qualification, Experience, Salary, Doj)
Values(@Emp_no, @Emp_name, @phone, @Email, @Password, @Gender, @Dob, @Address, @Designation, @Qualification, @Experience, @Salary, @Doj)
End


Please help me. Thanks in advance.

Answer

You need to use SqlCommand.Parameters.AddWithValue:

cmd.Parameters.AddWithValue("@ParameterName", value);

or SqlCommand.Parameters.Add for other data types:

cmd.Parameters.Add("@ParameterName", SqlDbType.Int, 5);
cmd.Parameters["@ParameterName"].Value = value;

SqlCommand.Parameters.AddWithValue replaces the ambiguous overload of Add that took a string and object parameter. See MSDN for more info.
