Oracle SQL 中如何获取某列中某些值的总和以及所有行的总和？
问题描述 投票：0回答：1
我有 3 个表，我想在 SSRS 报告中对其进行摘要。我在形成如何执行此操作的存储过程时遇到了一些问题。这是我正在考虑做什么的一个粗略示例。我想循环遍历所有具有与
C.CASE_ID以下是
PERSON.T_PERSON P我的数据库会有这样的东西：
FCB - 红、红、蓝、NA
FCT - 蓝色，蓝色，NA，NA
FCA - 紫色、粉色、NA、粉色
FCB = 婴儿时最喜欢的颜色
FCT = 青少年时最喜欢的颜色
FCA = 成人最喜欢的颜色
FOR X IN (SELECT M.CDE_KEY , M.DESC COUNTRY
FROM MASTER.TABLE_VALUES M
WHERE TABLE_NAME IN ('COL1'))
LOOP
SELECT FCB, FCT, FCA FROM PERSON.T_PERSON P, PERSON.T_CASE_PERSON C
WHERE P.IDN_INDIV = C.IDN_INDIV
AND SUBSTRING((LPAD(C.CASE_ID,6,0),0,2) = X.CDE_KEY;
Cursor - M.CDE_KEY || '-' || M.DESC As COUNTRY, SUM ("Red"),
SUM("Blue"), SUM("NA") etc..
END LOOP

假设您的数据可能与此类似：
WITH -- S a m p l e D a t a :
T_PERSON AS
( Select 1 as IDN_INDIV, 'Red' as FCB, 'Blue' as FCT, 'Purple' as FCA From Dual Union All
Select 2, 'Red', 'Blue', 'Pink' From Dual Union All
Select 3, 'Blue', 'NA', 'NA' From Dual Union All
Select 4, 'NA', 'Red', 'Pink' From Dual Union All
--
Select 1, 'NA', 'White', 'Pink' From Dual Union All
Select 2, 'Blue', 'Green', 'NA' From Dual Union All
Select 3, 'NA', 'NY', 'Black' From Dual Union All
--
Select 2, 'Red', 'Blue', 'NA' From Dual Union All
Select 3, 'Red', 'NA', 'Green' From Dual Union All
Select 4, 'Brown', 'Green', 'NA' From Dual Union All
--
Select 1, 'Pink', 'Blue', 'Blue' From Dual Union All
Select 3, 'Brown', 'NA', 'NA' From Dual Union All
Select 4, 'NA', 'Red', 'Pink' From Dual Union All
--
Select 1, 'Red', 'Blue', 'Pink' From Dual Union All
Select 2, 'Blue', 'Green', 'NA' From Dual Union All
Select 4, 'White', 'Na', 'Black' From Dual
),
T_CASE_PERSON AS
( Select 1 as IDN_INDIV, '01-aaa' as CASE_ID From Dual Union All
Select 2, '02-bbb' From Dual Union All
Select 3, '03-ccc' From Dual Union All
Select 4, '04-ddd' From Dual
),
TABLE_VALUES AS
( Select 'COL1' as TABLE_NAME, '01' as CDE_KEY, 'France' as DESCRIPT From Dual Union All
Select 'COL1', '02', 'America' From Dual Union All
Select 'COL1', '03', 'India' From Dual Union All
Select 'COL1', '04', 'Wales' From Dual
),
...一种选择可能是使用 Oracle MODEL 子句来获取通过求和准备的三组中的所有颜色...
grid AS
( Select *

PINK_FCT[ANY, ANY, 'Pink', ANY] = 1,

...现在使用 UNION 获取所有国家/地区的总行以及每个国家/地区的行
