INSERT INTO ... SELECT ... ON DUPLICATE KEY

Question

我有這樣的一個表：

CREATE TABLE `UserTmp` (
`user_id` bigint(20) unsigned NOT NULL, 
`nb_invit` bigint(20) unsigned DEFAULT '0', 
`nb_share` bigint(20) unsigned DEFAULT '0', 
`nb_sent` bigint(20) unsigned DEFAULT '0', 
`total` bigint(20) unsigned DEFAULT '0', 
PRIMARY KEY (`user_id`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8 

，我想，以執行這樣的（一個每桌3個查詢有nb_share，nb_invit和nb_sent）：

INSERT INTO UserTmp (user_id, nb_share) 
    select user_id, count(share_date) as 'nb_share' 
    from Share 
    where share_date between '2012-05-21 00:00:00' and '2012-05-28 00:00:00' 
ON DUPLICATE KEY UPDATE nb_share=VALUES(nb_share); 

與nb_share場等於存在於表CURENT用戶的份額的數量和需要更新

我們的目標是讓用戶的列表與他們的數字行動和行動d總字段，它是用戶完成的操作的總和。

VALUES（nb_share）接縫給我所有用戶的nb_share總數，而不是當前用戶的總數。

你有想法解決這個問題嗎？

感謝

Answer 1

您需要組SELECT通過user_id：

INSERT INTO UserTmp (user_id, nb_share) 
    SELECT user_id, count(share_date) 
    FROM  Share 
    WHERE share_date BETWEEN '2012-05-21 00:00:00' AND '2012-05-28 00:00:00' 
    GROUP BY user_id 
ON DUPLICATE KEY UPDATE nb_share = VALUES(nb_share) 

Answer 2

或者你可以使用一個用戶定義的變量：

INSERT INTO UserTmp (user_id, nb_share) 
    SELECT user_id, @nbshare := count(share_date) 
    FROM  Share 
    WHERE share_date BETWEEN '2012-05-21 00:00:00' AND '2012-05-28 00:00:00' 
    GROUP BY user_id 
ON DUPLICATE KEY UPDATE nb_share = @nbshare
