If you use global temporary tables and sequence, you may encounter some problems. Because global temporary tables are associated with sessions (or transactions in a session), sequence is related to the database level.In 12C, you can create a sequence that is used only for a given session.--When the global temporary table GTT is emptied in a session (such as commit), the value of sequence is not reset.
