integrity rule meaning in English
完整性规则
Examples
- Referential integrity rules
引用完整性规则 - A traditional application would need to maintain tables for each of these data items and enforce integrity rules
“传统的”应用程序必须要维护存储这些数据项的表并实施完整性约束。 - As part of the foreign - key constraint , you can specify referential integrity rules that are applied at three points
作为外键约束的一部分，可以指定在三个时候应用的引用完整性规则： - Otherwise , the database is likely to raise an error because referential integrity rules will prevent you from deleting a parent record while related child records still exist
否则，数据库很可能引发错误，因为引用完整性规则将阻止您在相关子记录仍存在的情况下删除父记录。 - If the database itself is enforcing relational integrity rules , then it will raise errors if you send the new child records to the database before the parent record has been created
如果数据库本身强制关系完整性规则，那么当您在创建父记录之前将新的子记录发送到数据库时，数据库将引发错误。
