SQL Update Script for Between Product Codes


I need a SQL Script to update my Products Table.

I have Product Code & Barcodes in the Products Table like:
Product Code  Barcode
ABC                   123456789

I need to put a zero in front of the number so:
Product Code  Barcode
ABC                   0123456789

Can someone please provide an update script for between a product code range to add the zero in front of the barcode number?

My Table is called: Products
My Fields are called: ProductCode & ProductBarcode

What is the final goal? A certain length like 10 char barcodes with leading 0s?

You can do that by right('0000000000'+ Barcode, 10)

declare @sampledata as table (barcode varchar(10));
insert into @sampledata values ('123'),('4567'),('987654321');

Select right('0000000000'+barcode,10) as paddedbarcode from @sampledata;
Select FORMAT(try_convert(int,barcode), 'd10') as paddedbarcode from @sampledata;

Open in new window

Once you're happy with the result the update is

Update yourtable Set barcode = ... Where Len(barcode)<10

Open in new window

That assumes a varchar barcode field with varying length.

Or in other examples it may be a 9 in front.

I want to run this script between a range of product codes though.

Length is not a concern.

update Products
set ProductBarcode = '0'+ProductBarcode
where ProductCode between  'ABC' and 'DEF'

Well, if you want to prefix a 0 you implicitly want a +1 length. The one and the other way to describe the demand are interchangable.
