三种随便密码生成sql存储过程

usp_RandomPassword CREATE PROCEDURE [dbo].[usp_RandomPassword]
(
@Length INT = 8
)
AS
BEGIN
DECLARE @RandomPassword NVARCHAR(MAX) = N'',@L INT = 1
WHILE @L <= @Length --循环密码长度
BEGIN
--随机产生每一位字符，ASCII码48至122
DECLARE @RndChar CHAR(1) = CHAR(ROUND(RAND() * (122-48+1) + 48,0))
--随机产生的字符不包括下面字符
IF ASCII(@RndChar) NOT IN(58,59,60,61,62,63,64,91,92,93,94,95,96) -- : , ; , <, = , > , ? ,@ , [ , , ] , ^ , _ , `
BEGIN
SET @RandomPassword = @RandomPassword + @RndChar
SET @L = @L + 1
END
END
SELECT @RandomPassword
END
