Question
Create random ID Unique
Hello,
I have a table with two columns (RecordName, Id). I'm trying to create an 8 Character ID unqiue for each record using the characters A-Z (except for the letters L,O,I). The characters will need to be random and unique (the Ids should be executed using a stored procedure).
I'm not sure if I can create an array and loop through it for each record...
Does anyone have any suggestions?
I started by creating a temp table with the letters in there, but then I wasn't sure how to do the rest or if it should be done differently. I would appreciate the input.
Thanks,

The characters that are created represent projects for studies in-house which this id will be later incoporated into Other project Ids. I need to make sure that the ID created is 8 characters in lenght and is combination of letters A-Z except for L,O and I. Each record must have these unique strand of characters.
passandhu, I tried your code and I got an error:
Incorrect Syntax near the Keyword 'Select'.
the user will be able to request this for only certain records, but I wanted to make sure that i can create this strand of characters before moving to the next phase.
I would appreciate the assistance thx.
UPDATE MyTable
SET ID =
REPLACE(REPLACE(REPLACE(RE
Alright so this will do what you are looking for.
Hope this helps.
P.
Here wrap this is in a function:
Declare @T table (C tinyint)
Declare @C tinyint,
@Value varchar(8)
SET @C = 48
While @C <= 90
Begin
IF (@C BETWEEN 48 AND 57 Or @C BETWEEN 65 And 90) And @C Not In (73, 76, 79)
INSERT @T (C) Values (@C)
SET @C = @C + 1
END
Set @Value = ''
Select TOP 8
@Value = @Value + CHAR(C)
FROM @T
ORDER By
NEWID()
Select @Value
>>Would you be able to just explain to me what is happening in the syntax... just for my own benefits.<<
First of all I was not entirely serious when I posted that. I do not believe that T-SQL it the right place to do that. That is entirely a presentation layer problem that is best addressed with something like .NET.
But to answer your question here is what it does:
1. Inserts into a table all the valid values.
2. Picks 8 values at random ( NEWID() )
3. Concatenates them into a string.

Why do u need a character Unique id, you can use uniqueidentifier column
select newId () always gives you unique values
