I am trying to cast an AuctionId that is a UNIQUEIDENTIFIER to an varchar(36) and then back to an UNIQUEIDENTIFIER. Please help me.

CAST((SUBSTRING(CAST([AuctionId] as VARCHAR(36)), 0, 35) + '1') AS UNIQUEIDENTIFIER)

But I keep getting this error:

Msg 8169, Level 16, State 2, Line 647 Conversion failed when converting from a character string to uniqueidentifier.

Thanks in advance
