That sound correct. But I worry that will force people to handle this case in their code. What is the good usage of 0000-00-00? What others think about it? PS: it seem some tests still failed |

Looks good to me, just need to make sure this is not a patch-level release. And it's shown in the changelog. |

return 0 as zero value of date/datetime to tell difference from NULL and '0000-00-00'.
e.g. insert/update a NOT NULL date column, only '0000-00-00' or 0 is valid.
