我在这里找到了一些可以更新一个字段的东西:http : //www.karlrixon.co.uk/articles/sql/update-multiple-rows-with-different- values-and-a-single-sql- query/
UPDATE person SET name = CASE id WHEN 1 THEN 'Jim' WHEN 2 THEN 'Mike' WHEN 3 THEN 'Precious' END WHERE id IN (1,2,3)
我的问题是如何更新多个字段?如:
UPDATE person SET name = CASE, sex = CASE id WHEN 1 THEN 'Jim', 'female' WHEN 2 THEN 'Mike', 'male' WHEN 3 THEN 'Precious', 'male' END WHERE id IN (1,2,3)
这当然是行不通的。尝试了其他几种组合并失败了。任何的想法?谢谢!
