SELECT yourData FROM Emplyees WHERE EmployeeId = someGUID
But use parameterized queries.

Do not exhaust your brain for useless thoughts! An employee is a human being, isn't he? How many people are there on earth? The max number of that datatype is more than a 1000million times bigger.

Solution 2

There is several data types[^] and each type has its limitation (in a simple manner).
I'd suggest to use GUID, as is described here: NEWSEQUENTIALID[^] and here: UNIQUEIDNETIFIER[^]. Please, read all notes.
