ERROR 1787 (HY000): Statement violates GTID consistency: 
CREATE TEMPORARY TABLE and DROP TEMPORARY TABLE can only be executed outside transactional context. 
These statements are also not allowed in a function or trigger because functions and triggers are also 
considered to be multi-statement transactions.

ERROR 1785 (HY000): Statement violates GTID consistency: 
Updates to non-transactional tables can only be done in either autocommitted statements or 
single-statement transactions, and never in the same statement as updates to transactional tables.
