我正在编写一个 SQL 查询来获取一个表的数据,并使用多个或嵌套 SQL 语句或使用表变量将其与更多数据连接起来,然后再使用连接.
I am writing a SQL query to fetch the data of one table and join it with some more data either using multiple or nested SQL statements or using table variable and then use join later.
条件是,如果Spends Table
中的Medium
列是TV
,那么在Output Table
TV_Spends
应显示电视的 Spends
和该特定市场牌.这同样适用于 Medium Print
.
The condition is that if the Medium
column in Spends Table
is TV
then in the Output Table
the TV_Spends
should show the Spends
of TV and that particular market & Brand. And this same is for Medium Print
.
另外一个条件是,如果Spends Table
中的Type
列是CWB,那么该Primary_Brand的Spendscode> 和
Medium
不应用于 TV_Spends
和 Print_Spends
计算.
Also, another condition is that if the Type
column in Spends Table
is CWB then the Spends of that Primary_Brand
and Medium
should NOT be used in TV_Spends
and Print_Spends
calculation.
Total_Spends
是该 Brand_Key
的 TV_Spends
和 Print_Spends
的总和市场
Total_Spends
is sum of TV_Spends
and Print_Spends
for that Brand_Key
& Market
支出表
Primary_Brand_Key | 中 | 市场 | 类型 | 花费 |
---|---|---|---|---|
Kornet | 电视 | 英国 | NULL | 1000 |
Kornet | 电视 | 波兰 | NULL | 2000 |
Kornet | 打印 | 波兰 | NULL | 3000 |
Kornet | 打印 | NULL | CWB | 7000 |
Tamas | 电视 | 英国 | NULL | 9000 |
预期产出表
Primary_Brand | 市场 | TV_Spends | Print_Spends | Total_Spends |
---|---|---|---|---|
Kornet | 英国 | 1000 | NULL | 1000 |
Kornet | 波兰 | 2000 | 3000 | 5000 |
Tamas | 英国 | 9000 | NULL | 9000 |
输出即将到来
Primary_Brand | 市场 | TV_Spends | Print_Spends | Total_Spends |
---|---|---|---|---|
NULL | NULL | NULL | NULL | 1000 |
NULL | NULL | NULL | NULL | 5000 |
NULL | NULL | NULL | NULL | 9000 |
NULL | NULL | NULL | NULL | NULL |
NULL | NULL | NULL | 3000 | NULL |
NULL | NULL | NULL | NULL | NULL |
NULL | NULL | 1000 | NULL | NULL |
NULL | NULL | 2000 | NULL | NULL |
NULL | NULL | 9000 | NULL | NULL |
NULL | 英国 | NULL | NULL | NULL |
NULL | 波兰 | NULL | NULL | NULL |
NULL | 英国 | NULL | NULL | NULL |
Kornet | NULL | NULL | NULL | NULL |
Kornet | NULL | NULL | NULL | NULL |
Tamas | NULL | NULL | NULL | NULL |
我编写的 SQL 查询给出了 Output Coming
输出,但是输出应该是 Expected Output Table
:-
SQL Query I have written which is giving the Output Coming
output, However the Output should be Expected Output Table
:-
declare @output_table_spends table
(
primary_brand_var nvarchar(255),
market_var nvarchar(255),
tv_spends decimal(11,2),
print_spends decimal(11,2)
total_spends_var decimal(11,2)
)
Insert into @output_table_spends (primary_brand_var)
select Primary_Brand_Key from
dbo.Spends
Insert into @output_table_spends (market_var)
select Market from
dbo.Spends
Insert into @output_table_spends (tv_spends)
select sum(Amount_Spent_INR)
from dbo.Spends
where medium='TV'
group by Market
Insert into @output_table_spends (print_spends)
select sum(Amount_Spent_INR)
from dbo.Spends
where medium='Print'
group by Market
Insert into @output_table_spends (total_spends_var)
select sum(tv_spends,print_spends)
from dbo.Spends
group by Market
select * from dbo.Spends
select distinct A.Primary_Brand_Key, A.Market,
B.tv_spends, B.print_spends, B.total_spends_var
from dbo.Spends A
inner join @output_table_spends B
on A.Primary_Brand_Key=B.primary_brand_var
group by A.Primary_Brand_Key, A.Market, B.tv_spends, B.print_spends, B.total_spends_var
如果我关注你想要的,你可以使用条件聚合:
If I'm following what you want, you can use conditional aggregation:
select primary_brand_key, market,
sum(case when medium = 'TV' and type <> 'CWB' then spends else 0 end) as tv,
sum(case when medium = 'print' and type <> 'CWB' then spends else 0 end) as print,
sum(spends)
from spends s
group by primary_brand_key, market;
您的问题表明 'CWB'
仅用于 tv
和 print
列.但是,如果您真的想要所有三个都使用它,请改用 where
子句.
Your question suggests that the 'CWB'
is only needed for the tv
and print
columns. However, if you really want it for all three, then use a where
clause instead.
