Like levels RR and RS, level Cursor Stability (CS) ensures that any row that was changed (or a row that is currently locked with an UPDATE row lock) by another activation group using a different commitment definition cannot be read until it is committed. Unlike RR and RS, level CS only ensures that the current row of every updatable cursor is not changed by other activation groups using different commitment definitions. Thus, the rows that were read during a unit of work can be changed by other activation groups that use a different commitment definition. In addition to any exclusive locks, an activation group running at level CS may acquire a share lock for the current row of every cursor.
In the SQL 2003 Core standard, Cursor Stability is called Read Committed.
Db2® for i supports cursor stability through COMMIT(*CS).
