选择行另外两个

Question

我是想选择一个特定的记录，它满足如果column1 = column2 + column3

SELECT gtt_id , 
    column1, 
    SUM(NVL(column2, 0) + NVL(column3, 0)) AS total 
FROM my_table where column1 = total 
GROUP BY gtt_id, 
column1; 

我收到以下错误条件：

ORA-00904: "TOTAL": invalid identifier

Answer 1

您不应该在同一个查询中使用total，因为您需要将查询包装并在外部循环中使用该查询。

SELECT gtt_id,column1,total 
FROM 
(
SELECT gtt_id , 
     column1, 
     SUM(NVL(column2, 0) + NVL(column3, 0)) total 
FROM my_table 
--where column1 = total 
GROUP BY gtt_id, 
column1 
) 
where column1 = total;
