12.25-rasm. Ma'lumotlar bazasidagi jadval elementlari va ma'lumotlar to'plamidagi
jadval o'rtasidagi yozishmalar jadvali Kompilyatsiya qilishdan oldin forma shakli 12.26-rasmda ko'rsatilgan. Biz tugmachasini bosib dasturni kompilyatsiya qilamiz. Kompilyatsiya muvaffaqiyatli bo'ldi. Ilovani keyingi ko'rinishi 12.27-rasmda ko'rsatilgan. Ma'lumotlarni ma'lumotlar bazasidan jadvalga yuklash tugmasini bosing. Natija 12. 28- rasmda ko'rsatilgan. Keling, qatorlar o'chirilganligini, qatorlar qo'shilganligini, ba'zi qator maydonlarining qiymatlari o'zgartirilganligini va nihoyat tuzatilgan jadval ma'lumotlar bazasiga qaytarilganligini tekshirib ko'raylik. Ushbu harakatlarning natijalari 12.29 va 12.30-rasmlarda ko'rsatilgan. Ilova qator qo'shish rejimida sinovdan o'tkazilganda (bu Navigatorning "Plus" tugmasi yordamida amalga oshirildi, bu maydon ma'lumotlari kiritiladigan bo'sh qatorni yaratadi), dasturlash muhiti qator kalitini ko'rsatishni talab qildi, ya'ni 1-ustun ustunidagi maydon qiymati. Bu juda noqulay, chunki jadvalda ko'p qatorlar mavjud bo'lganda kalit maydonning qiymatini yagona tanlash qiyin. Ma'lum bo'lishicha, bu muammodan chiqishning yo'li bor. DataSetda jadval ustunlarining xossalarini ochishingiz va Column1 kalit maydoni uchun AutoIncrement xususiyatini (avtomatik bir marta oshirish) False dan true ga o'zgartirishingiz kerak (12.31-rasm). Yuqoridagi yechimni amalga oshiradigan dastur 12-2 ro'yxatda ko'rsatilgan. 12.26-rasm. Formaning kompilyatsiya qilishdan oldin ko'rinishi 12.27-rasm. Formani kompilyatsiya qilish va bajarishdan keyingi ko'rinishi 12.28-rasm. Ma'lumotlar bazasidan "Mualliflar" jadvalini yuklash 12.29-rasm. Xotirada (ekranda) "Mualliflar" jadvali tuzatildi va ma'lumotlar bazasiga qaytarildi 12.30-rasm. "Mualliflar" jadvalini qayta o'qish 12.31-rasm.
