Why am I getting an error with my parameterized ADO query?
Dim txtFName As TextBox = CType(Wizar开发者_JS百科d1.FindControl("txtFName"), TextBox)
Dim txtLName As TextBox = CType(Wizard1.FindControl("txtLName"), TextBox)
Dim MyDbConnection As New SqlConnection(ConfigurationManager.ConnectionStrings.Item("Journeyeast Connection String").ToString)
MyDbConnection.Open()
Dim SQL = "INSERT INTO Registration(FName, LName) VALUES (@FName, @LName)"
Dim MySqlCommand As New SqlCommand(SQL, MyDbConnection)
MySqlCommand.Parameters.Add("@FName", SqlDbType.NChar, 10, txtFName.Text)
MySqlCommand.Parameters.Add("@LName", SqlDbType.NChar, 10, txtLName.Text)
MySqlCommand.ExecuteNonQuery()
I am getting the following error:
The parameterized query '(@FName nchar(10),@LName nchar(10))INSERT INTO Registration(FNam' expects the parameter '@FName', which was not supplied.
What am I doing wrong?
BTW, I know nchar(10)
is not a good choice for first and last name.
Because you haven't supplied parameter values.
Take a look at:
Dim SQL = "INSERT INTO Registration(FName, LName) VALUES (@FName, @LName)"
Dim MySqlCommand As New SqlCommand(SQL, MyDbConnection)
MySqlCommand.Parameters.AddWithValue("@FName",txtFName.Text)
MySqlCommand.Parameters.AddWithValue("@LName",txtLName.Text)
MySqlCommand.ExecuteNonQuery()
EDIT:
MySqlCommand.Parameters.Add("@FName", SqlDbType.NChar, 10).Value = txtFname.Text
MySqlCommand.Parameters.Add("@LName", SqlDbType.NChar, 10).Value = txtFname.Text
