Реших, че вашият solId
беше за solitications
. Първоначално мислех, че означава твърд (като скала). Така че това може да стане чрез композиция.
Имайте предвид, че в предоставената схема имаше няколко печатни грешки. Някои липсват запетаи, някои подменени имена на индекси. MyISAM таблица се промени на INNODB. Затова направих малко преименуване. Освен това около table5 липсваха маси. Така че не е така, сякаш вашият скрипт ще се изпълнява (за таблица rfqs
).
По същия начин следната схема ще се провали поради предоставените ви липсващи таблици, някъде около 60 до 70 процента през нея.

compTableX001
е като мини йерархия TwoParents-OneChild с име ID
. Така че ID
е името на родителството. Той има два родителя (BaseRFQId
и SolId
) и едно дете (NSNId
). Името или идентификаторът, като ID
, е FK целта на baserfqssols
ред, който поддържа. Посочено и Справка , съответно.
По същия начин, compTableX002
изглежда решава сега условията за въпрос 2.
