6.9.12.12 errors.Warning Exception

This exception is used for reporting important warnings, however, Connector/Python does not use it. It is included to be compliant with the Python Database Specification v2.0 (PEP-249).

Consider using either more strict Server SQL Modes or the raise_on_warnings connection argument to make Connector/Python raise errors when your queries produce warnings.

errors.Warning is a subclass of the Python StandardError.
