報表總計
此資訊描述明確指定報表總計聚總規則的方式，這有助於改善效能，且專為編寫 Oracle Analytics 報表的技術開發人員所設計。
在本範例中，報表定義為年度、月份以及客戶區域，且使用 'Count Distinct of Customers with Orders' 度量，其定義為計算訂單的相異客戶。
邏輯查詢如下：
SELECT
0 s_0,
"A - Sample Sales"."Cust Regions"."C50 Region" s_1,
"A - Sample Sales"."Counts"."32 # of Cust with Orders (Cnt Distinct)" s_2,
REPORT_AGGREGATE("A - Sample Sales"."Counts"."32 # of Cust with Orders (Cnt Distinct)" BY ) s_3
FROM "A - Sample Sales"
WHERE
("Time"."T02 Per Name Month" = '2011 / 11')
ORDER BY 2 ASC NULLS LAST
FETCH FIRST 500001 ROWS ONLY產生的實體查詢如下：
WITH
SAWITH0 AS (select count(distinct T42433.Cust_Key) as c1,
T42430.Region as c2
from
BISAMPLE.SAMP_CUSTOMERS_D T42428 /* D60 Customers */ ,
BISAMPLE.SAMP_ADDRESSES_D T42430 /* D62 Customers Addresses */ ,
BISAMPLE.SAMP_TIME_MTH_D T42405 /* D02 Time Month Grain */ ,
BISAMPLE.SAMP_REVENUE_F T42433 /* F10 Billed Rev */
where ( T42405.Mth_Key = T42433.Bill_Mth_Key and T42405.Per_Name_Month = '2011 / 11' and T42428.Cust_Key = T42433.Cust_Key and T42428.Address_Key = T42430.Address_Key )
group by T42430.Region),
SAWITH1 AS (select count(distinct T42433.Cust_Key) as c1
from
BISAMPLE.SAMP_TIME_MTH_D T42405 /* D02 Time Month Grain */ ,
BISAMPLE.SAMP_REVENUE_F T42433 /* F10 Billed Rev */
where ( T42405.Per_Name_Month = '2011 / 11' and T42405.Mth_Key = T42433.Bill_Mth_Key ) )
select D1.c1 as c1, D1.c2 as c2, D1.c3 as c3, D1.c4 as c4 from ( select D1.c1 as c1,
D1.c2 as c2,
D1.c3 as c3,
D1.c4 as c4
from
(select 0 as c1,
D1.c2 as c2,
D1.c1 as c3,
D2.c1 as c4,
ROW_NUMBER() OVER (PARTITION BY D1.c2 ORDER BY D1.c2 ASC) as c5
from
SAWITH0 D1,
SAWITH1 D2
) D1
where ( D1.c5 = 1 )
order by c2 ) D1 where rownum <= 500001
總計值 480 為成員值的總和 (182 + 113 + 185)。計算總計的邏輯查詢表示式為：“REPORT_AGGREGATE("A - Sample Sales"."Counts"."32 # of Cust with Orders (Cnt Distinct)" BY ) s_3”。
使用 “REPORT_AGGREGATE” 時，總計將獨立於成員值以外計算。但對於此報表設計，我們認為正確的總計可以從成員計算而得。
編輯資料欄公式，將 “Aggregation Rule (Totals Row)” 從 “Server Complex Aggregate” 變更為 “Sum”。這會變更邏輯和實體 SQL。
原始聚總：
修改後的聚總：
修改後的邏輯 SQL 現在包含 “REPORT_SUM”。
SELECT
0 s_0,
"A - Sample Sales"."Cust Regions"."C50 Region" s_1,"A - Sample Sales"."Counts"."32 # of Cust with Orders (Cnt Distinct)" s_2,
REPORT_SUM("A - Sample Sales"."Counts"."32 # of Cust with Orders (Cnt Distinct)" BY ) s_3
FROM "A - Sample Sales"
WHERE
("Time"."T02 Per Name Month" = '2011 / 11')
ORDER BY 2 ASC NULLS LAST
FETCH FIRST 500001 ROWS ONLY產生的實體查詢如下：

工作簿中提供可明確設定聚總的相同選項：
請複查您的報表，確認報表使用最佳聚總規則。當報表設計允許時，請使用明確聚總規則。
