Oracle Query giving error "ORA-00933: SQL command not properly ended"

Question

SELECT *
FROM
  (SELECT *
   FROM RHSTRYWLN7.RESULT R
   INNER JOIN RHSTRYWLN7.PRODUCT P ON P.PRODUCT_CODE=R.PRODUCT_CODE
   WHERE SOURCE_GUID='i0ad0105800000151b126c1c49def32b4'
     AND DELETED='F'
     AND DATE_CREATED > systimestamp-90
     AND DATE_CREATED < systimestamp) AS A
INNER JOIN
  (SELECT S.result_guid,
          count(document_guid) DocCount
   FROM RHSTRYWLN7.RESULT S
   INNER JOIN RHSTRYWLN7.document D ON D.result_guid=S.Result_guid
   WHERE SOURCE_GUID='i0ad0105800000151b126c1c49def32b4'
     AND DELETED='F'
     AND DATE_CREATED > systimestamp-90
     AND DATE_CREATED < systimestamp
   GROUP BY S.result_guid) AS B ON A.Result_guid=B.Result_guid

Am trying to run the above query in sqldeveloper and getting error saying:

ORA-00933: SQL command not properly ended.

When I run the sub queries independently it runs fine. What could be the issue?

Answer 1

You don't need the As when giving a name to a subquery. You can try the below

SELECT *
    FROM
      (SELECT *
       FROM RHSTRYWLN7.RESULT R
       INNER JOIN RHSTRYWLN7.PRODUCT P ON P.PRODUCT_CODE=R.PRODUCT_CODE
       WHERE SOURCE_GUID='i0ad0105800000151b126c1c49def32b4'
         AND DELETED='F'
         AND DATE_CREATED > systimestamp-90
         AND DATE_CREATED < systimestamp) A
    INNER JOIN
      (SELECT S.result_guid,
              count(document_guid) DocCount
       FROM RHSTRYWLN7.RESULT S
       INNER JOIN RHSTRYWLN7.document D ON D.result_guid=S.Result_guid
       WHERE SOURCE_GUID='i0ad0105800000151b126c1c49def32b4'
         AND DELETED='F'
         AND DATE_CREATED > systimestamp-90
         AND DATE_CREATED < systimestamp
       GROUP BY S.result_guid) B ON A.Result_guid=B.Result_guid

Answer 2

对表别名使用AS关键字不是 ANSI SQL 标准。并且 Oracle 不支持。

同样适用于 FROM 子句中使用的子查询，称为内联视图 。请勿使用AS关键字。

Answer 3

请尝试以下查询并检查

SELECT R.*,
       count(document_guid) OVER (PARTITION BY result_guid) DocCount
  FROM RHSTRYWLN7.RESULT R
 INNER JOIN RHSTRYWLN7.PRODUCT P 
    ON P.PRODUCT_CODE=R.PRODUCT_CODE
 INNER JOIN RHSTRYWLN7.document D 
    ON D.result_guid=R.Result_guid
 WHERE SOURCE_GUID='i0ad0105800000151b126c1c49def32b4'
   AND DELETED='F'
   AND DATE_CREATED > systimestamp-90
   AND DATE_CREATED < systimestamp
