Use while loop through table

Needed a solution to loop through a sql resultset without a temp table / table variable / cursor.

My answer: http://stackoverflow.com/questions/1578198/can-i-loop-through-a-table-variable-in-t-sql/7417780#7417780

declare @id int

        SELECT @id = min(fPat.PatientID)
        FROM tbPatients fPat
        WHERE (fPat.InsNotes is not null AND DataLength(fPat.InsNotes)>0)

while @id is not null
begin
    SELECT fPat.PatientID, fPat.InsNotes
    FROM tbPatients fPat
    WHERE (fPat.InsNotes is not null AND DataLength(fPat.InsNotes)>0) AND fPat.PatientID=@id
    
    SELECT @id = min(fPat.PatientID)
    FROM tbPatients fPat
    WHERE (fPat.InsNotes is not null AND DataLength(fPat.InsNotes)>0)AND fPat.PatientID>@id
        
end
