      Parameterised queries

      Hi,

      I am getting an error message saying:

      “No value given for one or more required parameters.” And it points to this line
      command.Execute NonQuery()

      I am not sure what this means. The code I used is below:


      Code:
      With command.Parameters

                    .Add(New OleDbParameter("@Firstname", FirstName.Text))

                    .Add(New

              replied to Inserting records into MS Access where there is an autonumber for a primary key
              in Access
              i got the code to work by naming the columns in the INSERT INTO statement. Before, i had only named the VALUES fields and not the columns in the database. Also the autonumber field (CustomerID) had to be left out. So the query now would be:
              Code:
              INSERT INTO Customer [B](FirstName, LastName, Address ect...)   [/B] 
VALUES('"FirstName.Text + "','" + LastName.Text + "','" + Address.Text ect..)
