Database Error
-
I tried to insert some value to a table, I received the following error
no value given for one or more required parametersHere is the code; the ID field is the primary key autoincremented, I don't know how to set it; I simply set it to 1OleDbConnection dbConnection; dbConnection = new OleDbConnection(); dbConnection.ConnectionString = "Provider = Microsoft.Jet.OLEDB.4.0; " + "Data Source = " + Application.StartupPath + "\\Data.mdb"; string sqlstr = "INSERT INTO Datas(ID, FirstName, LastName , Function, Description, SDate, EDate, THour)" + "VALUES(1, John, Do, FunctionOne, DescriptionOne, 12-02-03, 12-02-06, 20)";//dates are text OleDbCommand cmd = new OleDbCommand(sqlstr, dbConnection); try { dbConnection.Open();//open the database cmd.ExecuteNonQuery(); dbConnection.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message, "Database Error"); } -
