在Hana中使用with子句创建表

Question

我想使用with子句创建一个表：

例如：

with cte as
(SELECT B.STEUC "HSN",
        CASE WHEN A.FORMAT_CD='520' THEN '2' ELSE A.FORMAT_CD END FORMAT_CD,
        CASE WHEN A.FORMAT_CD='520' THEN 'DIGITAL' ELSE A.FORMAT_DESC END FORMAT_DESC,
        A.ARTICLE,
        A.REGION "STATE",
        SUM(CASE WHEN BWART IN ('702','704','708','711','713','715','717','551','553','555','903','909','951','Z09') THEN DMBTR ELSE 0 END) - 
        SUM(CASE WHEN BWART IN ('701','703','707','712','714','716','718','552','554',' 556','904','910','952','Z10') THEN DMBTR ELSE 0 END) "LOSS_VALUE"
FROM "_SYS_BIC"."RRA.DnL/CV_STOCK_MOVEMENT" A INNER JOIN "P22"."MARA" B ON A.ARTICLE=B.MATNR 
WHERE posting_date BETWEEN '20181101' AND '20181130' AND
      BWART IN ('702','704',' 708',' 711','713','715','717','701','703','707','712','714','716','718','551',
      '552','553','554','555','556','903','904','909','910','951','952','Z09','Z10') AND
      A.COMPANY_CODE='9008' AND
      A.LEVEL2 NOT IN ('10','99') AND
      A.LEVEL5 NOT IN ('140601010') AND
      A.FORMAT_CD NOT IN ('51','56','62','509')
GROUP BY B.STEUC,A.ARTICLE,A.REGION,A.COMPANY_CODE,A.FORMAT_CD,
        A.FORMAT_DESC)
SELECT A.HSN,
       A.STATE,
       A.FORMAT_CD,
       A.FORMAT_DESC,
       A.ARTICLE,
       A.LOSS_ART,
       B.LOSS
FROM (
SELECT A.HSN,
          A.STATE,
       A.FORMAT_CD,
       A.FORMAT_DESC,
       A.ARTICLE,
       A.LOSS LOSS_ART,
       SUM(A.LOSS) OVER (PARTITION BY A.HSN,A.STATE,A.FORMAT_CD ORDER BY  LOSS DESC) LOSS   
FROM (SELECT A.HSN,A.STATE,A.FORMAT_CD,A.FORMAT_DESC,A.ARTICLE,SUM(LOSS_VALUE) LOSS FROM 
--"RR_ANALYST"."REETIKA_LOSS_DATA_1" 
cte A 
INNER JOIN P22.MARA B ON A.ARTICLE=B.MATNR
      WHERE B.ATTYP<>'11'
      GROUP BY A.HSN,A.STATE,A.FORMAT_CD,A.FORMAT_DESC,A.ARTICLE 
      HAVING SUM(LOSS_VALUE)>0 ) A
      ) A ,
      (SELECT A.HSN,A.STATE,A.FORMAT_CD,SUM(LOSS_VALUE) LOSS FROM 
      cte  A 
      group by A.HSN,A.STATE,A.FORMAT_CD HAVING SUM(LOSS_VALUE)>0) B
  WHERE A.HSN=B.HSN AND
        A.STATE=B.STATE AND
        A.FORMAT_CD=B.FORMAT_CD AND
        A.LOSS<=B.LOSS*1

我猜 Hana 不支持这一点。

有什么可以替代它？ hana 是否像 oracle 一样支持假脱机？

我知道我可以导出结果集，然后相应地创建一个表。

但是有没有办法实现动态创建表呢？

Answer 1

另一种选择是“老式”方式 - 内联视图。

CREATE column TABLE t AS 
  SELECT * 
  FROM (SELECT 1 as some_value  --> this is your WITH factoring clause
        FROM dummy
        UNION ALL 
        SELECT 2 
        FROM dummy
      );

Answer 2

按 B.STEUC、A.ARTICLE、A.REGION、A.COMPANY_CODE、A.FORMAT_CD 分组， A.FORMAT_DESC),
