我有以下几点:
DROP TABLE [dbo].[ExtraUserinformation]; DROP TABLE [dbo].[UserProfile]; DROP TABLE [dbo].[webpages_Membership]; DROP TABLE [dbo].[webpages_OAuthMembership]; DROP TABLE [dbo].[webpages_Roles]; DROP TABLE [dbo].[webpages_UsersInRoles]; CREATE TABLE [dbo].[ExtraUserinformation] ( [Id] INT IDENTITY (1,1) NOT NULL,[UserId] INT NOT NULL,[FullName] NVARCHAR (MAX) NULL,[Link] NVARCHAR (MAX) NULL,[Verified] BIT NULL,CONSTRAINT [PK_dbo.ExtraUserinformation] PRIMARY KEY CLUSTERED ([Id] ASC) ); CREATE TABLE [dbo].[webpages_UsersInRoles] ( [UserId] INT NOT NULL,[RoleId] INT NOT NULL,PRIMARY KEY CLUSTERED ([UserId] ASC,[RoleId] ASC),CONSTRAINT [fk_UserId] FOREIGN KEY ([UserId]) REFERENCES [dbo].[UserProfile] ([UserId]),CONSTRAINT [fk_RoleId] FOREIGN KEY ([RoleId]) REFERENCES [dbo].[webpages_Roles] ([RoleId]) );
但是,这是一个失败的消息说:
Msg 3726,Level 16,State 1,Line 6 Could not drop object 'dbo.UserProfile' because it is referenced by a FOREIGN KEY constraint. Msg 3726,Line 9 Could not drop object 'dbo.webpages_Roles' because it is referenced by a FOREIGN KEY constraint. Msg 2714,State 6,Line 27 There is already an object named 'UserProfile' in the database. Checking identity information: current identity value 'NULL',current column value 'NULL'. DBCC execution completed. If DBCC printed error messages,contact your system administrator.
在这种情况下,我该怎么放桌子?
