当使用 ROWNUM 作为伪列时，您将如何使用 T-SQL 编写以下查询？这是完整的查询。我意识到它是用 PL/SQL 编写的，我需要更改添加对象。
BASE AS (
SELECT NULL AS ES_CMPNY_STATUS_KEY
,CSG.CMPNY_STATUS_GROUP
,CSG.CMPNY_STATUS_GROUP_ID
,CSG.CMPNY_STATUS_REASON
,CSG.CMPNY_STATUS_REASON_ID
,CSF.CMPNY_CURRENT_STATUS_FLAG
,TRUNC(SYSDATE) AS LOAD_DATE
FROM CMPNY_STATUS_GROUP CSG
CROSS JOIN CMPNY_CURRENT_STATUS_FLAG CSF
ORDER BY CSG.CMPNY_STATUS_GROUP, CSG.CMPNY_STATUS_REASON
)SELECT ROWNUM AS ES_CMPNY_STATUS_KEY
,CMPNY_STATUS_GROUP
,CMPNY_STATUS_GROUP_ID
,CMPNY_STATUS_REASON
,CMPNY_STATUS_REASON_ID
,CMPNY_CURRENT_STATUS_FLAG
,LOAD_DATE
FROM BASE B
UNION
SELECT 0 AS ES_CMPNY_STATUS_KEY
,NULL AS CMPNY_STATUS_GROUP
,0 AS CMPNY_STATUS_GROUP_ID
,NULL AS CMPNY_STATUS_REASON
,0 AS CMPNY_STATUS_REASON_ID
,0 AS CMPNY_CURRENT_STATUS_FLAG
,TRUNC(SYSDATE) AS LOAD_DATE
FROM DUAL
