mysql - 请帮助将 4 个 MySQL 查询合并为一个

Question

UPDATE RIA.Contact SET title = REPLACE(title, 'Cheif', 'Chief') where title rlike 'Cheif';
UPDATE RIA.Contact SET title = REPLACE(title, 'Manger', 'Manager') where title rlike 'Manger';
UPDATE RIA.Contact SET title = REPLACE(title, 'Manging', 'Managing') where title rlike 'Manging';
UPDATE RIA.Contact SET title = REPLACE(title, 'Excutive', 'Executive') where title rlike 'Excutive';

我们可以将上面的 4 个合并为这样的内容吗:UPDATE table SET A = IF(A > 0 AND A < 1, 1, IF(A > 1 AND A < 2, 2, A)) WHERE A IS NOT NULL;

我知道我们可以使用过程来做到这一点，但是是否可以仅使用查询？

我试过了 -

UPDATE RIA.Contact SET title = IF(title rlike 'Cheif', replace(title,'Cheif','Chief'), IF(title rlike 'Manger', replace(title,'Manger','Manager'))) WHERE title rlike 'Cheif' or title rlike 'Manger';

不许走!
