create table UserDetails ( id int identity(1,1) primary key, name varchar(50) not null, --真实姓名 userId int, foreign key (userId) references UserInfo(UserId) on delete cascade )
2、表结构已存在时添加
ALTER TABLE [dbo].[API_User_Label] WITH CHECK Add CONSTRAINT [FK_API_User_Label_API_SearchLabel] FOREIGN KEY([LabelId])
REFERENCES [dbo].[API_SearchLabel] ([Id]) on delete cascade
