ADO Command Object
Bevelvoorwerp
Die ADO Command-objek word gebruik om 'n enkele navraag teen 'n databasis uit te voer. Die navraag kan aksies uitvoer soos die skep, byvoeging, herwinning, uitvee of opdatering van rekords.
As die navraag gebruik word om data te herwin, sal die data as 'n RecordSet-objek teruggestuur word. Dit beteken dat die opgespoorde data gemanipuleer kan word deur eienskappe, versamelings, metodes en gebeure van die Recordset-objek.
Die belangrikste kenmerk van die Command-objek is die vermoë om gestoorde navrae en prosedures met parameters te gebruik.
