In SQLite there's Get<T> method which accept primary key as argument and it will return the row as object. Update method accept the object as parameter and it will update the existing record. Here I am giving you method to update person record.
private void UpdateRecord(int primaryKey)
{
var dbpath = System.IO.Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "data.db3");
using (var db = new SQLite.SQLiteConnection(dbpath))
{
var objPerson = db.Get<person>(primaryKey);
objPerson.name = "New name";
objPerson.address = "New address ";
objPerson.phone = Convert.ToDouble("New phone number");
db.Update(objPerson);
//You don't need to use db.Commit(), db.Dispose() & db.Close() because you are using "using" keyword.
}
}
