if exists (select * from sysobjects where id = OBJECT_ID(‘[Menu]‘) and OBJECTPROPERTY(id, ‘IsUserTable‘) = 1) DROP TABLE [Menu] CREATE TABLE [Menu] ( [ID] [bigint] IDENTITY (1, 1) NOT NULL, [MenuName] [nvarchar] (200) NULL, [Menu_ICON] [bigint] NOT NULL DEFAULT (0), [Menu_URL] [varchar] (500) NULL, [ParentID] [bigint] NOT NULL DEFAULT (0), [AddTime] [datetime] NOT NULL, [ICON_URL] [varchar] (500) NULL) ALTER TABLE [Menu] WITH NOCHECK ADD CONSTRAINT [PK_sys_menu] PRIMARY KEY NONCLUSTERED ( [ID] ) SET IDENTITY_INSERT [Menu] ON
