GUID is not an official data type in database. In our existing SQL Server design, the Uniqueidentifier type is used for GUID value. Now we are switching to Sybase database. Should we use varchar(36) to replace that Uniqueidentifier type?

I am still confused by GUID. I was told GUID is 16 bytes long but its character string is 36 characters in length. I must missed something.
