您已经有了可以找到问题所在的查询，那么为什么不使用not EXISTS
select fd1.id
from file_data fd1
where not exists
(
SELECT 1 FROM file_data fd2 WHERE (source collate latin1_swedish_ci = 'any' or destination collate latin1_swedish_ci ='any') and fd2.id = fd1.id
)
and not exists
(
SELECT 1 FROM file_data fd3 WHERE comment = '' and fd3.id = fd1.id
)
and not exists
(
SELECT 1
from file_data a
join ( SELECT source, destination, hit_counts, service
from file_data
group by source, destination, hit_counts, service
having count(*) > 1 ) b
on a.source = b.source
and a.destination = b.destination
and a.hit_counts = b.hit_counts
and a.service = b.service
and a.id = fd1.id
)
嗨，我试过了！但是，我一直收到这个错误致命错误：当我上传一个没有错误的文件时，在151行的C:\xampp\htdocs\fwrule\fw\reviewfile.php中对非对象执行成员函数的调用。第151行是$InsertData->execute；。
