Privet vsem.
Pomogite pojaluista, ya ne mogu rasobratsya, ne poluchaetsya dalshe!
Ya napisal script kotoriy generiruet 8-snachnie chisla. Eti chisla sapominautsya v base dannih.
U menya nikak ne poluchaetsya napisat sleduysheu chast scripta, ya uje proboval raslichnimi metodami
(@ snak pered oshibkoi; raslichnie zikli for; i raslichnie zikli while), no ne kak ne dobilsy resultata.
Esli odno is sgenerirovanih chisel povtoritsy s chislom kotoroe uje sapomnino v base dannih,
ono doljno ne sapominatsy v basu dannih i ne vidavat oshibki,
a generirovat novie/novoe chisla/chislo dla povtornogo sapominaniya.
V etom sluchae doljno sapominatsy po 3 chisla.
Ya privoju sdes moi script s soedineniem s basoi dannih i tablizu v kotoroi vse sapominaetsya.
Jdu pomoshi, spasibo.
