Cursor Stability (CS), Repeatable Read (RR), Read Stability (RS), Uncommitted Read (UR). Cursor stability holds locks as long the cursor is position on the row. Repeatable read holds locks on all the rows on both qualifying and non-qualifying rows. Read stability holds locks only on qualifying rows only. Uncommitted read does not takes any locks but does take latches instead.
