Length of a guid

[cpopham]

I am creating a database and want to create GUIDs in vb .net to use in the database. I can not find the answer to my question. How many characters are in a GUID or is it random after a minimum amount of characters?

Thanks, Chester

GUIDS are not really character strings, rather they are a binary value that is often displayed in one or more character based formats. IIRC they are 128 bits (16 bytes).

guid = 16 hex values
a varchar(16) or char(16) should do.
