When you enforce referential integrity, SQL Server prevents users from doing any of the following:

Adding records to a related table if there is no associated record in the primary table

Changing values in a primary table that result in orphaned records in a related table

Deleting records from a primary table if there are related records in the foreign table

我的英文不太好,但试一下

当你强制参照完整性时,sqlserver禁止用户以下操作:
当主键表中无关联记录时向关联表添加记录
更改主键表记录的值使关联表中的记录成为无关联记录
当外键表中存在与主键表关联记录时删除主键表中的记录
