使用mysql中經(jīng)常會(huì)遇到的問(wèn)題，記錄下來(lái)

轉(zhuǎn)自： http://database.e800.com.cn/articles/2007/630/1183147360019880660_1.html

select bid from board where not in (select bid from favorite)

但在

mysql里就提示SQL語(yǔ)句的語(yǔ)法不對(duì)，“...near ''select bid from favorite)''

--------------------------------------------------------------------------------

在MySQL中下列語(yǔ)句還不能工作：

SELECT * FROM table1 WHERE id IN (SELECT id

FROM table2);

SELECT * FROM table1 WHERE id NOT IN (SELECT id FROM

table2);

然而，在很多情況下，你可以重寫(xiě)查詢(xún)，而不用子選擇：

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%''
