ADO - verbindingsvoorwerp
Verbindingsvoorwerp
Die ADO Connection Object word gebruik om 'n oop verbinding met 'n databron te skep. Deur hierdie verbinding kan u toegang tot 'n databasis verkry en dit manipuleer.
As jy verskeie kere toegang tot 'n databasis wil hê, moet jy 'n verbinding met die Connection-objek bewerkstellig. Jy kan ook 'n verbinding met 'n databasis maak deur 'n verbindingstring deur 'n Command of Recordset-objek deur te gee. Hierdie tipe verbinding is egter net goed vir een spesifieke, enkele navraag.
