Question

我有一个名为auditrtailreference的表，我通过运行以下查询来获取一些数据

SELECT t3.destinationid AS input,
    t1.sourceid AS Raw,
    t1.outtime::TEXT,
    t6.destinationid AS out_file,
    t4.outtime::TEXT AS out_time,
    t1.bytes AS inbytes,
    t6.bytes AS outbyte,
    t5.cdrs AS inputcdrs,
    t6.cdrs AS outputcdrs,
    t6.partial_cdrs,
    t6.duplicate_cdrs,
    t6.discarded_cdrs,
    t6.created_cdrs,
    t6.corrupted_cdrs,
    t6.created_files,
    t6.duplicate_files,
    t6.corrupted_files,
    t6.partial_files,
    t6.discarded_files,
    t6.empty_files
FROM auditrtailreference t1
LEFT JOIN auditrtailreference t2 ON t2.sourceid = t1.destinationid
    AND t2.event = '80'
    AND t2.innodename LIKE 'SDP%_SFTP'
LEFT JOIN auditrtailreference t3 ON t3.sourceid = t2.destinationid
    AND t3.event = '68'
LEFT JOIN auditrtailreference t4 ON t4.sourceid = t3.destinationid
    AND t4.event = '67'
    AND (
        t4.innodename LIKE 'SDP%_Collector'
        OR t4.innodename LIKE 'SDP%_collector'
        )
LEFT JOIN auditrtailreference t5 ON t5.sourceid = t4.destinationid
    AND t5.event = '73'
LEFT JOIN auditrtailreference t6 ON t6.destinationid LIKE t3.destinationid || '%'
    AND t6.event = '68'
    AND (
        t6.outnodename LIKE 'SDP%_distributer'
        OR t6.outnodename LIKE 'SDP%_Arch'
        OR t6.outnodename LIKE 'SDP%_distributor'
        OR t6.outnodename LIKE 'SDP%_Distributor'
        OR t6.outnodename LIKE 'SDP%_Distributer'
        )
WHERE t1.event = '67'
    AND t1.innodename LIKE 'SDP%_SFTP'
    AND t3.destinationid LIKE '%'
    AND t1.outtime >= '2014/09/09 00:00'
    AND t1.outtime <= '2014/09/10 19:51'
    AND t3.outnodename LIKE '%init_Dist';

现在我需要删除从中获取有效数据的所有行（这里的有效数据意味着我获取的所有列必须不为空）

现在为什么我这样做是因为我正在接收文件形式的数据......我正在向这些表插入，现在我在后台运行一个守护进程，它获取必要的数据并插入另一个表

在此之后，我需要删除已插入到最终表

的初始表中的所有行

您需要识别表中的主键（auditrtailreference），并且可以从SELECT查询创建DELETE

也许就是这样的例子：

DELETE FROM auditrtailreference
WHERE ROW_ID IN 
  (select ROW_ID from auditrtailreference... JOIN .... WHERE...)

从中获取数据后删除行
