经常做数据库访问性能测试时,需要用到数据量很大的表,自己动手写一段TSQL语句即可。
TSQL_生成表结构:/**//****** 对象: 表 [dbo].[LargeTable];脚本日期: 2006-10-26 15:40:27 ******/if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[LargeTable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[LargeTable]GO
/**//****** 对象: 表 [dbo].[LargeTable];脚本日期: 2006-10-26 15:40:27 ******/CREATE TABLE [dbo].[LargeTable] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [Title] [nvarchar] (100) COLLATE Chinese_PRC_CI_AS NULL , [Content] [ntext] COLLATE Chinese_PRC_CI_AS NULL , [PublicTime] [datetime] NULL , [Author] [nvarchar] (10) COLLATE Chinese_PRC_CI_AS NULL , [IsTop] [tinyint] NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]GO
ALTER TABLE [dbo].[LargeTable] WITH NOCHECK ADD CONSTRAINT [PK_LargeTable] PRIMARY KEY; CLUSTERED ( [ID] ); ON [PRIMARY] GO
