Question

删除约束时没有运气...我以“sa”身份登录，应该有足够的权限来执行它但我仍然得到：

Msg 4902, Level 16, State 1, Line 6
Cannot find the object "dbo.Products" because it does not exist or you do not have permissions.

以下是查询：

USE [PRSS10_DATABASE]
    IF EXISTS (SELECT * 
      FROM sys.foreign_keys 
       WHERE object_id = OBJECT_ID(N'dbo.FK_Product_SMC')
       AND parent_object_id = OBJECT_ID(N'dbo.Products')
    )
      ALTER TABLE [dbo.Products] DROP CONSTRAINT [FK_Product_SMC]

现在我可以访问该表..该表存在，外键也是..我可以丢失什么？

Answer 1

它是括号。当你执行[dbo.products]时，会认为整个对象被命名为＆＃34; dbo.products＆＃34; 你想要的是[dbo].[Products]，以便它识别 ＆＃34; dbo＆＃34; 作为架构和＆＃34;产品＆＃34; 作为表名称。

Answer 2

修正语句如下：

ALTER TABLE [dbo].[Products] DROP CONSTRAINT [dbo].[FK_Product_SMC]

不能放弃约束
