我只想知道以下查询有什么问题：- 如果我们删除分页Rownum部分，它将正常工作。 提及以下查询：- 我们已经尝试了消除分页功能，但该方法有效，但是我们无法 使它可以处理分页及其给定的歧义错误。我还可以看到所有列都带有其tableName。

答案 0 :(得分：1)
您的内部查询具有多个名称相同的列，尽管它们来自不同的表；那些似乎是：
ACCT_ID (from DIM_HIERARCHY and TEMP_DCS)
CHARGE_GROUP_ID
INV_DATE
INVOICE_NUM
PRODUCT_TYPE_ID
外部查询无法解决这种歧义。您需要为冲突列添加别名，以使名称在外部查询中唯一。
作为该问题的简单演示：
SELECT *
FROM
(SELECT a.* ,
ROWNUM rnum
FROM
(
-- replacing your entire inner query with somethign simple
select dummy, dummy from dual
) a) WHERE rnum > 0
and rnum <= 10000;
SQL Error: ORA-00918: column ambiguously defined
00918. 00000 - "column ambiguously defined"
如果您为列添加别名，问题将消失：
SELECT *
FROM
(SELECT a.* ,
ROWNUM rnum
FROM
(
-- replacing your entire inner query with somethign simple
select dummy as dummy1, dummy as dumym2 from dual
) a) WHERE rnum > 0
and rnum <= 10000;
D D RNUM

X X 1
答案 1 :(得分：0)
您希望分页查询（如果使用rownum）采用以下形式：
select *
from ( select /*+ FIRST_ROWS(n) */
a.*, ROWNUM rnum
from ( your_query_goes_here,
with order by ) a
where ROWNUM <=
:MAX_ROW_TO_FETCH )
where rnum >= :MIN_ROW_TO_FETCH;
您似乎将上限和下限都放在同一位置（除其他外）。你有：
SELECT *
FROM
(SELECT a.* ,
ROWNUM rnum
FROM
(
select ...
ORDER BY TEMP_DCS.ACCT_ID, TEMP_DCS.INVOICE_NUM, TEMP_DCS.INV_DATE, DIM_HIERARCHY.GROUP_ID, DIM_HIERARCHY.SUB_ACCT_ID, DIM_HIERARCHY.SERVICE_ID) a)
WHERE rnum > 0 and rnum <= 10000
您可能想要：
select *
from ( select a.*, ROWNUM rnum
from ( select ... from ... ORDER BY ...) a
where ROWNUM <= 10000 )
where rnum >= 0;
