我有以下sql表达式：

SELECT SS_ITEM_SK AS POP_ITEM_SK 
FROM (SELECT SS_ITEM_SK 
FROM (SELECT SS_ITEM_SK,(ITEM_SOLD-ITEM_RETURNED) AS TOT_SOLD_QTY FROM (SELECT SS_ITEM_SK,COUNT(SS_ITEM_SK) AS ITEM_SOLD,COUNT(SR_ITEM_SK) AS ITEM_RETURNED FROM STORE_SALES1 right outer join STORE_RETURNS1 on SS_TICKET_NUMBER = SR_TICKET_NUMBER AND SS_ITEM_SK = SR_ITEM_SK GROUP BY SS_ITEM_SK)))  

INTERSECT 

SELECT CS_ITEM_SK AS POP_ITEM_SK FROM (SELECT CS_ITEM_SK
FROM (SELECT CS_ITEM_SK,(ITEM_SOLD-ITEM_RETURNED) AS TOT_SOLD_QTY FROM (SELECT CS_ITEM_SK,COUNT(CS_ITEM_SK) AS ITEM_SOLD,COUNT(CR_ITEM_SK) AS ITEM_RETURNED FROM CATALOG_SALES1 right outer join CATALOG_RETURNS1 on CS_ORDER_NUMBER = CR_ORDER_NUMBER and CS_ITEM_SK = CR_ITEM_SK  GROUP BY CS_ITEM_SK))) 

INTERSECT 

SELECT WS_ITEM_SK AS POP_ITEM_SK FROM (SELECT WS_ITEM_SK
FROM (SELECT WS_ITEM_SK,(ITEM_SOLD-ITEM_RETURNED) AS TOT_SOLD_QTY FROM (SELECT WS_ITEM_SK,COUNT(WS_ITEM_SK) AS ITEM_SOLD,COUNT(WR_ITEM_SK) AS ITEM_RETURNED FROM WEB_SALES1 right outer join WEB_RETURNS1 on WS_ORDER_NUMBER = WR_ORDER_NUMBER AND WS_ITEM_SK = WR_ITEM_SK GROUP BY WS_ITEM_SK)))

ApachePhoenix不支持关键字 INTERSECT . 有没有人能帮我在不使用 INTERSECT ?

我认为有多种方法可以做到这一点：
join方法

select * from ((query1 inner join query2 on column_names) inner join query3 on column_names)

exists方法

(query1 where exists (query2 where exists (query3)) )

in方法

(query1 where column_name in (query2 where column_name in (query3)) )

虽然我会使用exists/in over the join，因为如果这些查询返回大量数据，那么您可能必须使用以下命令优化查询：https://phoenix.apache.org/joins.html
