    Thanks so much. Is this case sensitive. You have all the names correct so I copied and pasted this before my executenonquery statment and there are red lines all over it. Okay I feel really dumb about now. It came up with ; errors so I'm guessing that I don't just copy exactly what you have done? Oh god. I'm waiting to be told off. ;)

    That was a SQL statement for creating a stored procedure in SQL Server. Once you create it in SQL Server, you can then call it using a class like SqlDataReader and use the method ExecuteNonQuery. Don't forget to add your parameters!

      Don't forget to use "Transaction" when you are trying to manipulate data from more than one table...

        betetr you use trigers (insert) to insert data in all table based on the employee table

        A trigger may not always be the best solution. You have to look at performance and other aspects also.

          As I read the thread, I was wondering about exactly this.

          Cheers, Vıkram.

                Okay I apologise for pasting so much info but I've done as you said. My code looks like this, but I get the null error which I've shown you at the bottom. If you can help, I'll vote you high for every message you've sent to me today. :rose: I notice that I got this same error when I was using my normal insert statement. what am I doing wrong you think? SqlCommand sqlC = new SqlCommand("sp_InsertEmployee", myConnection); sqlC.CommandType = CommandType.StoredProcedure; sqlC.Parameters.Add(new SqlParameter("@Firstname", SqlDbType.VarChar, 0, "Firstname")); sqlC.Parameters.Add(new SqlParameter("@Lastname", SqlDbType.VarChar, 50, "Lastname")); sqlC.Parameters.Add(new SqlParameter("@Role", SqlDbType.VarChar, 0, "Role")); sqlC.Parameters.Add(new SqlParameter("@Manager", SqlDbType.VarChar, 50, "Manager")); sqlC.Parameters.Add(new SqlParameter("@Division", SqlDbType.VarChar, 0, "Division")); //sqlC.Parameters[0].Value = 4; sqlC.Parameters[0].Value = FirsttextBox.Text.ToString(); sqlC.Parameters[1].Value = LasttextBox.Text.ToString(); sqlC.Parameters[2].Value = RolecomboBox1.Text.ToString(); sqlC.Parameters[3].Value = ManagercomboBox1.Text.ToString(); sqlC.Parameters[4].Value = DivisioncomboBox1.Text.ToString(); int i = sqlC.ExecuteNonQuery(); Error::::Cannot insert the value NULL into column 'RoleID', table 'Dev_RST.dbo.employees'; column does not allow nulls. INSERT fails. The statement has been terminated.

                  Okay it works only slightly but what I notice from this is that the firstname and lastname are update in employees but I've noticed also that I just want the ID's corresponding to that name to be updated also in the employee table istead of saving new entries into the other tables. For example there are now multiple roles called developer, or graduate just with different ID's when what I actually need to do is just update the employee table with the new person and the ID that corresponds to their selected role. Thanks and sorry for being a pain.

                    In reponse to Michael & Vikram, yes, you should be using transactions on multiple statements. The example I provided to you was based on your original post. If your intentions are not alwasy to insert records, then you will need to modify the stored procedure to check for the Roles, Managers, etc. If found then update your employee table. You will need to know SQL. If you are using a Listbox or Combobox, you can also save the PK in the control collection and just pass that to your stored procedure. There are many ways to kill this bird, it just depends on your requirements.

                      Okay but what about my last question. how do I update the employee table wiht the ID corresponding the combobox selection. EG. Employee table has empID, RoleID, DivisioID etc. But then I have a Role table with roleid description and role, and division table with divisionid, division etc. When a user enters a new employee name, and selects role for example, the employee table should update with a new name and put the correct roleID against the role. Obviously I'm not good with sql at all. :~
