We want to create a script that would create a value of 26 character length and have mixed characters from ascii value 65 thru 128.  We have so far:

select FLOOR(RAND(CHECKSUM(NEWID()))*(128-65))

Open in new window


But the values is lower that 65.

Also can't get to set for/next or loop to create a value of 26 random characters long.

Please advice.

Try.. This will give you different 26 characters each time.

SELECT LEFT(NEWID(),26)

O/p <<26 length>>

Great!!!

We were still working on a solution (obviously your way better):
DECLARE @X INT=1, @v varchar
WAY:  --> Here the  DO statement
  SET @X += 1
  set @v=@v + 'h'
IF @X<=26 GOTO WAY
select  @v 'Value'

Open in new window


Thanx!!

Can you explain a bit on 'SELECT LEFT(NEWID(),26)'?

NewID() will give us unique value of 36 length. It is of data type uniqueidentifier.

After that we just taking 26 characters with the help of LEFT function.

Hope it helps !!
