All referential cascade actions and constraint checks also must succeed before this trigger fires 所有的引用級(jí)聯(lián)操作和約束檢查也必須在激發(fā)此觸發(fā)器之前成功完成。
All referential cascade actions and constraint checks also must have been successful before this trigger fires 所有的引用級(jí)聯(lián)操作和約束檢查都成功完成后,才能激發(fā)此觸發(fā)器。
Any cascading actions defined on a related primary key will not be performed on rows that contain foreign keys that are disabled 將不對(duì)包含已禁用外鍵的行執(zhí)行對(duì)相關(guān)主鍵定義的任何級(jí)聯(lián)操作。
Similarly , the update option is not allowed on tables that have a referential relationship specifying a cascade action on update 同樣,也不允許對(duì)具有指定級(jí)聯(lián)操作on update的引用關(guān)系的表使用update選項(xiàng)。
This successful execution includes all referential cascade actions and constraint checks associated with the object updated or deleted 判斷執(zhí)行成功的標(biāo)準(zhǔn)是:執(zhí)行了所有與已更新對(duì)象或已刪除對(duì)象相關(guān)聯(lián)的引用級(jí)聯(lián)操作和約束檢查。
For instead of triggers , the delete option is not allowed on tables that have a referential relationship specifying a cascade action on delete 對(duì)于instead of觸發(fā)器,不允許對(duì)具有指定級(jí)聯(lián)操作on delete的引用關(guān)系的表使用delete選項(xiàng)。
