Hi friends,
I'm developing an application for HR. I have two tables so far.One is tblDetails and the other is Academic. I have created a relationship (ID to AcademicID), I have been able to pull data to a form by this SELECT statement:
sqlSearch = "SELECT tblDetails.ID, tblDetails.FirstName, tblDetails.Surname, Academic.AcademicID, Academic.FirstLevel, Academic.FirstAward, Academic.PlaceFirst, Academic.YearFirst " _
                    + "FROM tblDetails INNER JOIN Academic ON " _
                    + "tblDetails.ID = Academic.AcademicID " _
                    + "WHERE tblDetails.ID = '" & Trim(Me.txtSearch.Text) & "'"
 
        da = New OleDb.OleDbDataAdapter(sqlSearch, con)
        da.Fill(ds, "HumanResource")
        con.Close()
      
After pulling the data, I want to update this data (I think its the same as adding new data) and I tried to use this code:
            
           Dim updateCommand As New OleDb.OleDbCommandBuilder(da)
            ds.Tables("HumanResource").Rows(inc).Item("FirstLevel") = cmbFirstLevel.Text
            ds.Tables("HumanResource").Rows(inc).Item("FirstAward") = txtFirstAward.Text
            ds.Tables("HumanResource").Rows(inc).Item("PlaceFirst") = txtPlaceFirst.Text
            ds.Tables("HumanResource").Rows(inc).Item("YearFirst") = txtYearFirst.Text
 
            da.Update(ds, "HumanResource")
But this method does not work, with the following error msg "Dynamic SQL generation is not supported against multiple base tables."
Microsoft further says that "..This often occurs when the database table does not have a primary key column, or the SELECT command uses JOINS."
So I think I need custom codes for INSERT/UPDATE to work here, since I use JOIN. I have googled for the codes to no avail. Can someone help me please? The codes for UPDATE/INSERT where JOIN is used.
 
*I use an Access database.(.mdb)
 
Thanks in advance.
