I used this to generate a random password. You can change what it returns to up to an 8000 character password if you feel brave. You will need this function (http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=14924) to generate the random numbers. For some reason, occassionaly a NULL (CHAR(0)) character would get in there and mess things up so I had to remove those. You could change this to even include the non alpha numeric characters.
create procedure random_password
@length smallint,
@password nvarchar(256) = null output
as
set nocount on
declare @number int
declare @lower int
declare @upper int
declare @part tinyint
if @length > 256 set @length = 256
set @password = ''
while len(@password) < @length
begin
exec random_number 0, 3, @part output
if @part = 0
select @lower = ascii('a'),
@upper = ascii('z')
else if @part = 1
select @lower = ascii('A'),
@upper = ascii('Z')
else if @part = 2
select @lower = ascii('0'),
@upper = ascii('9')
set @part = null
set @number = null
exec random_number @lower, @upper, @number output
set @password = @password + ltrim(char(@number))
if substring(@password, len(@password), 1) = char(0) set @password = left(@password, len(@password) - 1)
end
go
