我下面這篇文章:MySQL分區唯一鍵
http://www.chrismoos.com/2010/01/31/mysql-partitioning-tables-with-millions-of-rows
但是當我運行我的查詢分割我的產品表(包含50萬行數據),我得到的錯誤:
#1503 - A UNIQUE INDEX must include all columns in the table's partitioning function
我的查詢是:
ALTER TABLE parts_library PARTITION by HASH(manufacturerId) PARTITIONS 200
我的主鍵是ID和毫安的化合物鍵nufacturerId,這是在文章中相同,所以我不明白爲什麼我得到這個錯誤。
這裏是我的表創建語句:
CREATE TABLE IF NOT EXISTS `parts_library` (
`id` int(11) NOT NULL,
`dateAdded` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`typeId` int(3) NOT NULL COMMENT 'Reference to part_types',
`manufacturerId` int(11) NOT NULL DEFAULT '0',
`familyId` int(11) NOT NULL DEFAULT '454',
`partNumber` varchar(255) COLLATE utf8_unicode_ci NOT NULL COMMENT 'e.g. 6ES5123B62',
`idealForm` varchar(255) COLLATE utf8_unicode_ci NOT NULL COMMENT 'E.g. 6ES5-123-B6/2',
`comCodeId` int(11) DEFAULT NULL,
`countryOriginId` int(3) NOT NULL DEFAULT '258',
`minStockLevel` int(11) DEFAULT NULL,
`weight` decimal(11,2) DEFAULT NULL,
`width` decimal(11,2) DEFAULT NULL,
`height` decimal(11,2) DEFAULT NULL,
`depth` decimal(11,2) DEFAULT NULL,
`validated` tinyint(1) NOT NULL DEFAULT '0',
`onWeb` tinyint(1) DEFAULT '0',
`indexed` tinyint(1) NOT NULL DEFAULT '1',
`averageMargin` decimal(11,2) NOT NULL,
PRIMARY KEY (`id`,`manufacturerId`),
UNIQUE KEY `partNumber` (`partNumber`),
KEY `fk_parts_library_parts_categories1` (`typeId`),
KEY `fk_parts_library_manufacturers1` (`manufacturerId`),
KEY `fk_parts_library_geo_countries1` (`countryOriginId`),
KEY `fk_parts_library_parts_families1` (`familyId`),
KEY `indexed` (`indexed`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
我如何分割我的表?
