How do you convert GUID to int?
An integer uses 32 bits, whereas a GUID is 128 bits – therefore, there’s no way to convert a GUID into an integer without losing information, so you can’t convert it back. EDIT: you could perhaps store the GUID into a GUIDs table where you assign each a unique integer ID.
How do I find my GUID?

To identify the version of the GUID, just look at the version digit e.g version 4 GUIDs have the format xxxxxxxx-xxxx-4xxx-Nxxx-xxxxxxxxxxxx where N is one of 8,9,A, or B. This version is generated using both the current time and client MAC address.
Should I use a GUID?
Use guids when you have multiple independent systems or clients generating ID’s that need to be unique. For example, if I have 5 client apps creating and inserting transactional data into a table that has a unique constraint on the ID, then use guids.
Is GUID really unique?
A GUID is a unique number that can be used as an identifier for anything in the universe, but unlike ISBN there is no central authority – the uniqueness of a GUID relies on the algorthm that was used to generate it.
Can GUID be primary key?
GUIDs can be considered as global primary keys. Local primary keys are used to uniquely identify records within a table. On the other hand, GUIDs can be used to uniquely identify records across tables, databases, and servers.

Should I use GUID or int?
An INT is certainly much easier to read when debugging, and much smaller. I would, however, use a GUID or similar as a license key for a product. You know it’s going to be unique, and you know that it’s not going to be sequential.
