While moving my wordpress blog to the new Google Cloud Hosting setup, the database would not import. This is due to MySQL being setup in strict mode by default in MySQL version 5.7 . One solution on the internet is to set MySQL’s SQL_MODE to “NO_ENGINE_SUBSTITUTION”, but Google knows better and won’t let you do that for security purposes. They do provide an option https://cloud.google.com/sql/docs/mysql/flags to alter the settings and allow for invalid dates. In the drop down as pictured, select “Allow Invalid Dates”. Then your wordpress database import will work.
