我可以做些什么来对付Kall服务器的制约因素?
原标题:What can I do about a SQL Server ghost FK constraint?

我感到有些麻烦的是2005年SQ服务器数据库,该数据库似乎像它保持了周围的幽灵限制。 我用一个文字来说明有关制约因素,做了一些工作,然后又再次提出同样的限制。 通常,它会做罚款。 然而,现在,它不得不重新处理这一制约因素,因为数据库说,它已经存在,尽管这一下降是不起作用的!

这里的问询是Im,涉及:

alter table individual drop constraint INDIVIDUAL_EMP_FK

ALTER TABLE INDIVIDUAL
   ADD CONSTRAINT INDIVIDUAL_EMP_FK
          FOREIGN KEY (EMPLOYEE_ID)
                         REFERENCES EMPLOYEE

在排除了限制之后,我确信,该物体确实是用以下询问取得的:

select object_id( INDIVIDUAL_EMP_FK )
select * from sys.foreign_keys where name like  individual% 

两者都没有结果(或没有结果),但在我试图再次提出质询时,我得到:

The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "INDIVIDUAL_EMP_FK". 

试图 drop倒,我得到的信息是,它确实存在。 任何想法?

最佳回答

它意味着数据在创建传统知识方面是错误的。

也就是说,在教育、教育、教育、教育、体育和体育部的家长表中,你有“EMPLOYEE_ID”的价值观。

页: 1 ALTER TABLE ......WITH NOCHECK ADDCONTRAINT...,但FK没有使用
