Bu yerda ADD tugmasi orqali malumot kiritilyapti va richTextBox ga qoshilip ketayapti va Malumotlarni bazaga saqlash tugmasi orqali bazaga malumotlar joylanyapti

Bu yerda bizga 0 qaytarayotkani sababi bazadagi malumotlarning yani butun sonlarning oxirgi raqami biz kiritgan raqam bilan tugamaganligi sababli bizga 0 qiymati qaytarilyapti

Bu esa bizning bazadagi malumotlar to’plami
