Sql密码生成器 - 8个字符,上下包含一个数字

Question

我需要在TSQL中创建一个新密码,该密码需要包含8个字符(az),其中必须包含上下字符以及至少一个数字.

谁能帮我这个？

Answer 1

select cast((Abs(Checksum(NewId()))%10) as varchar(1)) + 
       char(ascii('a')+(Abs(Checksum(NewId()))%25)) +
       char(ascii('A')+(Abs(Checksum(NewId()))%25)) +
       left(newid(),5)
from yourTable

Answer 2

需要考虑的事情,有点复杂:

SELECT      TOP 8
            SUBSTRING(tblSource.vsSource, tblValue.number + 1, 1) AS vsChar
FROM        (SELECT 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789' AS vsSource) AS tblSource
            JOIN master..spt_values AS tblValue 
                ON tblValue.number < len(tblSource.vsSource)
WHERE       tblValue.type = 'P'
ORDER BY    NEWID()

但非常随机.
