顯示SQL查詢的重複記錄

Question

我試圖在一週內看到對象的重複記錄。我有興趣看到重複項，而不是隻有一個實例的對象。這是我迄今寫的：

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; 

這將返回重複記錄，但不是每個重複記錄。有任何想法嗎？

對，你應該可以通過子查詢來處理這個問題。

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)
