OleDbCommandBuilder problem

How to change insert command generated by oledbcommandbuilder??

For ex. I have this code that creates data adapter and commands:

Dim daTrening as OleDbDataAdapter
Dim cbTrening as OleDbCommandBuilder

daTrening = New OleDbDataAdapter("select * from trening where clan_id=" & clanid, Conn_s)
daTrening.TableMappings.Add("Table", "Trening")
daTrening.Fill(data_set)
cbTrening = New OleDbCommandBuilder(daTrening)

By executing this msgbox:

MsgBox(cbTrening.GetInsertCommand.CommandText)

I found out that commandbuilder builds this insert command:

INSERT INTO `trening`( `clan_id` , `mjesec` , `brojtreninga` , `prisustvovao` ) VALUES ( ? , ? , ? , ? )"

I need that first "?" always be the number "7". How to change that ? I've tryed to build another command object and set that

insertcommand text, but the update method of data adapter seams to ignores it and always use the commandbuilder

insertcommand.

Help !
