代碼是心血來(lái)潮編寫(xiě)得，就象買(mǎi)彩票一樣，為國(guó)家做貢獻(xiàn)；
首先建立一個(gè)表，表得數(shù)據(jù)可以從福利彩票網(wǎng)站上獲得，自己一個(gè)一個(gè)得錄入進(jìn)去先；

表結(jié)構(gòu)為：

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tbSrcData]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[tbSrcData]
GO

CREATE TABLE [dbo].[tbSrcData] (
[Q] [varchar] (10) NOT NULL , --期數(shù)
[F1] [int] NULL , --1號(hào)球數(shù)
[F2] [int] NULL , --2號(hào)球數(shù)
[F3] [int] NULL , --3號(hào)球數(shù)
[F4] [int] NULL , --4號(hào)球數(shù)
[F5] [int] NULL , --5號(hào)球數(shù)
[F6] [int] NULL , --6號(hào)球數(shù)
[F7] [int] NULL , --7號(hào)蘭球數(shù)
[FXQT] [int] NULL --快樂(lè)星期天球數(shù)
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[tbSrcData] WITH NOCHECK ADD
CONSTRAINT [PK_tbSrcData] PRIMARY KEY CLUSTERED
(
[Q]
) ON [PRIMARY]
GO

CREATE UNIQUE INDEX [IX_tbSrcData] ON [dbo].[tbSrcData]([Q]) WITH IGNORE_DUP_KEY ON [PRIMARY]
GO


運(yùn)行以下代碼到查詢(xún)分析器內(nèi)：
