mysql 更新字段

更新字段

UPDATE familydb.familyinfo SET familyName = 'cuicui''s home' WHERE familyName = 'homenew';
同时更新相同字段不同值

UPDATE familydb.familyinfo SET familyName = CASE WHEN familyName = 'homenew' THEN 'cuicui''s home' WHEN familyName = 'lala' THEN '17611111118''s home' ELSE familyName END WHERE familyName IN ('homenew', 'lala');

注：一个变量里有引号，写两遍就可以了
同时更新不同字段

UPDATE users SET name = '张三', age = 30 WHERE id = 1;
