Explanation

Standard SQL isolation levels are Read Uncommitted (RU), Read Committed (RC), Repeatable Read (RR), and Serializable (S). CS (Cursor Stability) is a valid isolation level in DB2. SS is not one of the standard SQL isolation levels, though some systems use 'Snapshot Isolation' which SS might abbreviate.
