mysql - 显示 SQL 查询的重复记录

Question

我试图查看一个对象在一周内的重复记录。我有兴趣看到重复项，而不是只有一个实例的对象。这是我到目前为止写的:

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;

这会返回重复的记录，但不会返回重复的每条记录。有什么想法吗？

Answer 1

正确，因此您应该能够使用子查询处理此问题。

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)
