Yes, but what kind of operation I can use to proceed an input query from data base and manage Rows to add new column row["ID"] recieving a value from query ?
like this cmd = "Select MySequence.NEXTVAL from DUAL" execute this and set row["ID"] = reader["ID"]; I try to use AbstractCommandOperation. but i had problems with connections closed. this is how a tried to do... public override IEnumerable<Row> Execute(IEnumerable<Row> rows) { using (Connection) { using (Command) { foreach (var row in rows) { Command.CommandText = string.Format("SELECT Sequence.NEXTVAL as ID FROM DUAL"); using (Reader) { while (Reader.Read()) { row["ID"] = reader["ID"]; yield return row; } } } } } } Thank's again -- You received this message because you are subscribed to the Google Groups "Rhino Tools Dev" group.
