Answer 1

As a workaround you could add a column to your table, like locked TINYINT(1) - whenever you want the row to be locked you set it to 1. When you now try to access this row, the first thing you do is check if the locked fields is set.

To unlock the row, simply set it to 0 again. Not nice but a really simple workaround.
