在這裏插入圖片描述

其實這個報錯還是提示的挺明顯的，不知道大家有沒有發現我的hibernateSQL語句中，有兩個重複的quality ，刪除一個或是進行修改也行！！

SELECT
    avg(quality) as quality ,
    max(server_time) as server_time ,
    min(source_time) as source_time,
    count(tag) as tag ,
    sum(value) as value,
    sum(quality) as quality  
FROM
    metrics 
left join
    tags  
        on metrics.tag =  tags.node_id  
where
    metrics.tag =?  
    and server_time < NOW() - interval '30 minutes'

運行出來了 正確的結果！！！

在這裏插入圖片描述

或是你不明白，附上其他人的解釋 ···········在這裏插入圖片描述

更新 。。。 2018-08-15 17:45
還有可能是你的語句沒有 別名 【本人是寫查詢】

 @Query(value = "select tag ,value ,to_char(time,'yyyy-MM-dd hh24:MI:ss') from  xxxx order by time asc ",nativeQuery = true)

寫成：

 @Query(value = "select tag as t ,value as v ,to_char(time,'yyyy-MM-dd hh24:MI:ss') as ti from  xxxx order by time asc ",nativeQuery = true)

就可以了！！
