用一个查询更新多行？

Question

我找到了一些可以在这里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)

哪个当然不起作用.尝试了其他一些组合并失败了.任何的想法？谢谢!

UPDATE person
    SET name = CASE id
        WHEN 1 THEN 'Jim'
        WHEN 2 THEN 'Mike'
        WHEN 3 THEN 'Precious'
    END,
    sex = CASE id
        WHEN 1 THEN 'female'
        WHEN 2 THEN 'male'

你尝试过类似下面的东西吗？每列可以有一个"SET"语句.

UPDATE person 
    SET name = CASE id 
        WHEN 1 THEN 'Jim' 
        WHEN 2 THEN 'Mike' 
        WHEN 3 THEN 'Precious' 
    END, 
    sex = CASE id 
        WHEN 1 THEN 'female' 
        WHEN 2 THEN 'male' 
        WHEN 3 THEN 'male' 
    END 
WHERE id IN (1,2,3)
