SQL语句为:select * from table1 where `text` like CONCAT(‘%‘,(select name from table2 where id =3),‘%‘); UPDATE ecs_region a,nation b SET a.code = b.code where b.province like concat(‘%‘,a.region_name,‘%‘); UPDATE ecs_region a,nation b SET a.code = b.code where b.city like concat(‘%‘,a.region_name,‘%‘); UPDATE ecs_region a,nation b SET a.code = b.code where b.district like concat(‘%‘,a.region_name,‘%‘);
MYSQL 多表更新 UPDATE SET like concat('%',abc,'%');
