mysql - 在 MySQL 中进行子分区时出现语法错误

Question

尝试在 MySQL 中对表进行子分区时遇到语法错误。尝试对常规分区使用任何一种方法时都不会出现错误，只需进行子分区即可。最后两行导致了错误，我有点迷失了。

我还尝试将主分区的 KEY 切换为 HASH，将 LIST 切换为 RANGE，但仍然会引发错误。

  CREATE TABLE `map_polygon` (
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
    `district_id` int(10) unsigned NOT NULL DEFAULT '0',
    `map_type_id` int(10) unsigned DEFAULT NULL,
    `is_big_data` tinyint(1) DEFAULT '0',
    `polygon_group` int(10) unsigned DEFAULT NULL,
    `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
    `sort_order` int(10) unsigned DEFAULT NULL,
    `locations` mediumtext COLLATE utf8_unicode_ci,
    `north` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `south` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `east` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `west` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `group_north` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `group_south` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `group_east` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `group_west` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
    `created_at` timestamp NULL DEFAULT NULL,
    `updated_at` timestamp NULL DEFAULT NULL,
    `deleted_at` timestamp NULL DEFAULT NULL,
    `deleted_by_user_id` int(10) unsigned DEFAULT NULL,
    `created_by_user_id` int(10) unsigned NOT NULL,
    PRIMARY KEY (`id`,`district_id`, `is_big_data`),
    KEY `map_polygons_created_by_user_id_foreign` (`created_by_user_id`),
    KEY `map_polygons_deleted_by_user_id_foreign` (`deleted_by_user_id`),
    KEY `map_polygons_map_type_id_foreign` (`map_type_id`),
    KEY `map_polygons_district_id_foreign` (`district_id`),
    KEY `is_big_data` (`is_big_data`)
  ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci
  PARTITION BY LIST(is_big_data)
  PARTITIONS 2 (
    PARTITION pNormal VALUES IN (0),
    PARTITION pBigData VALUES IN (1)
  )
  SUBPARTITION BY KEY(district_id)
  SUBPARTITIONS 10;

Answer 1

似乎只是对分区子句进行了轻微的重新排列( http://www.sqlfiddle.com/#!9/9d746 )

  PARTITION BY LIST(is_big_data)
  SUBPARTITION BY KEY(district_id)
  SUBPARTITIONS 10
  (
    PARTITION pNormal VALUES IN (0),
    PARTITION pBigData VALUES IN (1)
  );
