mysql升级到5.7时,wordpress导数据报错1067的问题

最近把mysql升级到5.7了，wordpress导数据报错

Invalid default value for 'comment_date'

原因出在类似这样的语句

DROP TABLE IF EXISTS `wp_comments`;
CREATE TABLE `wp_comments`  (
  `comment_ID` bigint(20) UNSIGNED NOT NULL AUTO_INCREMENT,
  `comment_post_ID` bigint(20) UNSIGNED NOT NULL DEFAULT 0,
