turn warnings into errors by default?

[fillest]

e.g.

2014-01-29 13:10:44,998 WARNI [sqlalchemy.pool.QueuePool][MainThread] Error closing cursor: (1293, 'Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause')

("NULL values for timestamp are interperted as CURRENT_TIMESTAMP by default") with mysql < 5.6.5
