生成1千万个随机串号9位英文字母

今天上优快云社区的时候，发现这帖子，感觉顶有意思，就想一下写出一解决方法。这里顺便记录自己的解决方法。[@more@]原来问题：
请问一下，在SQL中怎么来做可以快速生成1千万个9位英文（大写）随机不重复的号码，非常着急，谢谢啦。

自己写的一个解决方法：

DECLARE @i int CREATE TABLE #AZ(X nchar ( 1 )) SET @i = 65 WHILE @i <= 90 BEGIN INSERT INTO #AZ SELECT CHAR ( @i ) SET @i = @i + 1 END SELECT TOP 10000000
A.X + B.X + C.X + D.X + E.X + F.X + G.X + .H.X + I.X AS X INTO #T1 FROM
( SELECT TOP 32 X FROM #AZ ORDER BY NEWID () DESC ) AS A
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID ()) AS B
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID () DESC ) AS C
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID ()) AS D
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID () DESC ) AS E
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID ()) AS F
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID () DESC ) AS G
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID ()) AS H
,( SELECT TOP 32 X FROM #AZ ORDER BY NEWID () DESC ) AS I WHERE A.X <> B.X AND A.X <> C.X AND A.X <> D.X AND A.X <> E.X AND A.X <> F.X AND A.X <> G.X AND A.X <> H.X AND A.X <> I.X AND B.X <> C.X AND B.X <> D.X AND B.X <> E.X AND B.X <> F.X AND B.X <> G.X AND B.X <> H.X AND B.X <> I.X AND C.X <> D.X AND C.X <> E.X AND C.X <> F.X AND C.X <> G.X AND C.X <> H.X AND C.X <> I.X AND D.X <> E.X AND D.X <> F.X AND D.X <> G.X AND D.X <> H.X AND D.X <> I.X AND E.X <> F.X AND E.X <> G.X AND E.X <> H.X AND E.X <> I.X AND F.X <> G.X AND F.X <> H.X AND F.X <> I.X AND G.X <> H.X AND G.X <> I.X AND H.X <> I.X -- 执行使用 1分20秒 PRINT GETDATE () -- 查询数据未测，因为电脑慢，呵呵
-- SELECT * FROM #T1 PRINT GETDATE () DROP TABLE #AZ,#T1

要是哪位朋友想到更好的方法可以写出，大家一起分享！
