显示SQL查询的重复记录

Question

我试图在一周内看到对象的重复记录。我有兴趣看到重复项，而不是只有一个实例的对象。这是我迄今写的：

SELECT a.asset, t.ticketnum, t.symptom_mask, t.setsolution, t.`otherdesc` 
    FROM lamarinfo AS a 
    JOIN lfso AS t 
    ON (a.id = t.asset_id) 
    WHERE open_dt BETWEEN CURDATE() - INTERVAL 7 DAY AND SYSDATE() 
GROUP BY a.`asset` HAVING COUNT(*) > 1; 

这将返回重复记录，但不是每个重复记录。有任何想法吗？

Answer 1

对，你应该可以通过子查询来处理这个问题。

SELECT a.asset, t.ticketnum, t.symptom_mask, t.setsolution, t.`otherdesc` 
    FROM lamarinfo AS a 
    JOIN lfso AS t 
    ON (a.id = t.asset_id) 
    WHERE a.asset IN (SELECT asset FROM lamarinfo WHERE open_dt BETWEEN CURDATE() - INTERVAL 7 DAY AND SYSDATE() GROUP BY asset HAVING COUNT(*) > 1)
