批量生成问题(冲值卡)
数据库里包含这两个字段，都是由系统顺序和随机生成
比如卡号　生成50个
MLAA00000001
MLAA00000050

下次在生成根据最后一个50　再生成50个
MLAA00000050
MLAA00000100

密码10位英文数字大小写(不需要0和o)

生成后具体结构为:
卡号                                                         密码
MLAA00000001                                         si34KFds43
-----------                                           ----------

求SQL语句，分不够在开～

------解决方案--------------------
Create Table TEST
(卡号 Char(12),
密码 Char(10))
GO
Select TOP 50 ID = Identity(Int, 1, 1) Into #T From SysColumns
--生成50條隨機數據
Insert TEST
Select
TOP 50
'MLAA ' + Right(100000000 + IsNull(Right((Select Max(卡号) From TEST), 4), 0) + ID, 8),
Left(Replace(Replace(Replace(NewID(), '- ', ' '), '0 ', ' '), 'o ', ' '), 10)
From #T

Select * From TEST

--再生成50條隨機數據
Insert TEST
Select
TOP 50
'MLAA ' + Right(100000000 + IsNull(Right((Select Max(卡号) From TEST), 4), 0) + ID, 8),
Left(Replace(Replace(Replace(NewID(), '- ', ' '), '0 ', ' '), 'o ', ' '), 10)
From #T

Select * From TEST

Drop Table #T
