过滤器MySQL时间戳

Question

我是新来的，并会感谢帮助！如果一个或多个“ID”缺少时间戳，需要删除行。例如，在下表中ID = 10没有IRIG_Time = 2014-05-15 09：05：00.000的值，因此我需要删除该时间戳的所有IRIG_Time行。我正在使用以下查询来提取数据（感谢Barmar的帮助！）。

CREATE TABLE Table1 
SELECT * 
FROM originaltable Where IRIG_Time between '2014/05/15 09:05' and '2014/05/15 09:35'; 
DELETE t.* FROM Table1 AS t 
JOIN (
SELECT IRIG_Time 
FROM Table1 
GROUP BY IRIG_Time 
HAVING COUNT(*) != 5 
) AS t1 ON t.IRIG_TIME = t1.IRIG_TIME; 
select * from Table1; 


IRIG_Time     ID  MagnitudeA 
2014-05-15 09:05:00.000  5  730406000 
2014-05-15 09:05:00.000  15  742456000 
2014-05-15 09:05:00.000  20  731190000 
2014-05-15 09:05:00.000  25  748572000 
2014-05-15 09:05:00.033  5  730343000 
2014-05-15 09:05:00.033  10  755865000 
2014-05-15 09:05:00.033  15  742347000 
2014-05-15 09:05:00.033  20  731168000 
2014-05-15 09:05:00.033  25  748574000 
2014-05-15 09:05:00.067  5  730420000 
2014-05-15 09:05:00.067  10  755767000 
2014-05-15 09:05:00.067  15  742310000 
2014-05-15 09:05:00.067  20  731176000 
2014-05-15 09:05:00.067  25  748524000 

当使用上面的代码，我得到错误代码：1175您正在使用安全更新模式，你尝试更新的表没有WHERE使用一个键列禁用安全模式，在首选项切换选项 - > SQL查询并重新连接。

Answer 1

DELETE t.* FROM table AS t 
JOIN (
    SELECT IRIG_Time 
    FROM table 
    GROUP BY IRIG_Time 
    HAVING COUNT(*) != (SELECT COUNT(DISTINCT ID) FROM table) 
    ) AS t1 ON t.IRIG_TIME = t1.IRIG_TIME

Answer 2

感谢您的帮助Barmar！我不得不修改“安全更新”首选项，但以下脚本正常工作！

Drop table Table1; 
CREATE TABLE Table1 
SELECT IRIG_Time, ID, MagnitudeA FROM originaltable 
Where IRIG_Time between '2014-05-25 13:00' and '2014-05-25 14:00' order by IRIG_Time; 

DELETE t.* FROM Table1 AS t 
JOIN (
SELECT IRIG_Time, ID 
FROM Table1 
GROUP BY IRIG_Time 
HAVING COUNT(*) != 5 
) AS t1 ON t.IRIG_TIME = t1.IRIG_TIME; 
select * from Table1;
