Question

尝试在MySQL中对表进行分区时遇到语法错误。尝试对常规分区使用这两种方法中的任何一种时都没有错误，仅通过子分区即可。是导致错误的最后两行，我有点迷茫。

我也尝试过将KEY切换为HASH，将LIST切换为RANGE为主分区，但是仍然会引发错误。

  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;

看起来（http://www.sqlfiddle.com/#!9/9d746）的分区子句只是重新排列了

 Sub zapiszpdf2()
Dim DATA As String
DATA = Format(Date, "dd-mm-yyyy")

Columns("E:F").EntireColumn.Hidden = True

 ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
       ActiveWorkbook.Path & "C_a_" & DATA & ".pdf", Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, IgnorePrintAreas:=False, From:=1, To:=1, OpenAfterPublish:=True


Columns("D:G").EntireColumn.Hidden = False
