Graeme Gillies commented on TEIID-1928:
---------------------------------------

Ahhhh sorry for wasting your time I figured it out.

The server stack trace revealed the error was coming from the mysql driver itself.

I then discovered the mysql jdbc driver has a property especially designed to configure what happens when you hit invalid dates like this

http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html

it's called zeroDateTimeBehavior and setting it to convertToNull in the connection string of the Datasource connection made the problem go away.

Not sure if it's worth mentioning in any teiid documentation or FAQ, but I guess we should make sure that property is set on all our mysql connection strings.

Feel free to close/reject this issue.

Thanks
