Question

我对SQL还是很陌生，我希望从两个查询中获得一个AVG函数（按组加入一个查询）。

我的查询模板。

WITH group1 AS (
SELECT 
          ID AS ID
         ,date AS date
         ,TYPE AS TYPE
         ,GROUP_M AS GROUP_M
         ,Value AS Value
         ,AVG (NULLIF( Value , 0)) OVER (PARTITION BY  TYPE  ) AS TYPE_AVG
FROM
(
SELECT  
          a4.id AS ID
         ,a0.data AS date
         ,GET_ATTRIBUTE_VALUE ( a12.attributes , Upper('TYPE'), '=') AS TYPE
         ,GET_ATTRIBUTE_VALUE ( a12.attributes , Upper('GROUP_M'), '=') AS GROUP_M
         ,a4.value AS Value
         ,a12.attributes AS attributes
FROM 
    SESSION a2
LEFT JOIN P_id a0 ON a0.id = a2.id
INNER JOIN P_SET a3 ON a3.id = a2.id 
WHERE
              a2.name = 'REVIEW' 
 AND      a2.test_name = '4M' 

 AND      a0.data >= TRUNC(SYSDATE) - 7 

)
),
group2 AS (
 SELECT 

         ,wch.id AS E_id
         ,e.entity AS Entity
FROM 
       F_machine wch
INNER JOIN F_Entity e ON e.entity = wch.entity 
INNER JOIN F_Run_card lrc ON lrc.lotoperkey = wch.lotoperkey
INNER JOIN F_Route r ON r.route=lrc.route AND r.facility = lrc.facility AND r.latest_version = 'Y'
WHERE
              e.entity Like 'E%' 
 AND      e.entity Is Not Null  
 AND      wch.end_time >= TRUNC(SYSDATE) - 14 
)
SELECT *
  FROM group1
  JOIN group2 ON group1.id = group2.E_id
;

我的最终目标是再增加一列-机器和类型的平均价值

AVG (NULLIF( {value} , 0)) OVER (PARTITION BY {machine} , {TYPE} )

谢谢，希望一切都清楚了:)

2个表格的平均功能
