MySQL使用ON DUPLICATE KEY插入/更新多行

Question

我正在尝试插入一个插入,如果它id已经存在,它会更新行,但我似乎无法让它工作.

这是插入的简化版本,因为可以插入/更新大约1400行.大多数情况下,该语句将充当多行UPDATE,每天将通过CRON作业运行.它应该更新现有的行,但如果添加了新项,则会将其插入数据库.

INSERT INTO `buoy_stations` (`id`, `coords`, `name`, `owner`, `pgm`, `met`, `currents`)
VALUES 
('00922', Point(30,-90),'name 1','owner 1','pgm 1','y','y'),
('00923', Point(30,-90),'name 2','owner 2','pgm 2','y','y'),
('00924', Point(30,-90),'name 3','owner 3','pgm 3','y','y'),
('00925', Point(30,-90),'name 4','owner 4','pgm 4','y','y'),
('00926', Point(30,-90),'name 5','owner 5','pgm 5','y','y')
ON DUPLICATE KEY
UPDATE coords=coords, name=name, owner=owner, pgm=pgm, met=met, currents=currents;

我做错了什么,这不起作用？它似乎必须在UPDATE基于错误的部分中.

#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use 
near 'pgm=pgm, met=met, currents=currents'

我已经阅读了文档,并查看了几个StackOverflow答案,但它们似乎反映了与语句相同的设置.

你忘记了values()关键词

INSERT INTO `buoy_stations` (`id`, `coords`, `name`, `owner`, `pgm`, `met`, `currents`)
VALUES 
('00922', 'Point(30,-90)','name 1','owner 1','pgm 1','y','y'),
('00923', 'Point(30,-90)','name 2','owner 2','pgm 2','y','y'),
('00924', 'Point(30,-90)','name 3','owner 3','pgm 3','y','y'),
('00925', 'Point(30,-90)','name 4','owner 4','pgm 4','y','y'),
('00926', 'Point(30,-90)','name 5','owner 5','pgm 5','y','y')
ON DUPLICATE KEY
        UPDATE coords=values(coords), name=values(name), owner=values(owner), pgm=values(pgm), met=values(met), currents=values(currents);
