Question

以下是查询

SELECT omt.actualendtime::date,
       (SELECT array_to_json(array_agg(row_to_json(t)))
        FROM (SELECT odt.productshortname,
                     count(odt.*) 
              FROM orderdetail_runtime_tran odt 
              WHERE odt.actualendtime::date = omt.actualendtime::date
                AND odt.stagename = 'Ironing'
              GROUP BY odt.productshortname
             ) t
       ) as item_current_count
From orderdetail_runtime_tran omt
WHERE omt.actualendtime IS NOT NULL AND date_part('year', omt.actualendtime) = '2019'
  AND omt.stagename = 'Ironing'
GROUP BY omt.actualendtime::date;

此查询给出了错误

子查询使用外部查询中未分组的列“ omt.actualendtime”

Answer 1

尝试使用子查询：

SELECT actualenddate,
       (SELECT array_to_json(array_agg(row_to_json(t)))
        FROM (SELECT odt.productshortname, count(odt.*) 
              FROM orderdetail_runtime_tran odt 
              WHERE odt.actualendtime::date = actualenddate AND
                    odt.stagename = 'Ironing'
              GROUP BY odt.productshortname
             ) t
       ) as item_current_count
FROM (SELECT omt.*,
             omt.actualendtime::date as actualenddate
      FROM orderdetail_runtime_tran omt
      WHERE omt.actualendtime IS NOT NULL AND 
            date_part('year', omt.actualendtime) = '2019' AND
            omt.stagename = 'Ironing'
     ) omt
GROUP BY actualenddate;

子查询使用外部查询中的未分组列“ omt.actualendtime”
