select bid from board where not in (select bid from favorite)
但在mysql里就提示SQL语句的语法不对，“...near ''select bid from favorite)''

在MySQL中下列语句还不能工作：
SELECT * FROM table1 WHERE id IN (SELECT id FROM table2);
SELECT * FROM table1 WHERE id NOT IN (SELECT id FROM table2);
然而，在很多情况下，你可以重写查询，而不用子选择：
SELECT table1.* FROM table1,table2 WHERE table1.id=table2.id;
SELECT table1.* FROM table1 LEFT JOIN table2 ON table1.id=table2.id where table2.id IS NULL

select a.user_name from tmp_user_user a left outer join briousr2 b on a.user_name=b.user_name where b.user_name is null and a.user_name not like ''%0%''
