    <p>I have the following:</p> <pre><code>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]) ); </code></pre> <p>However this is failing with a message saying:</p> <pre><code>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, Level 16, State 1, Line 9 Could not drop object 'dbo.webpages_Roles' because it is referenced by a FOREIGN KEY constraint. Msg 2714, Level 16, 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. </code></pre> <p>How can I drop a table in these circumstances?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
