I am trying to write a script that will combine specific survey results based on the demographs used in the survey. I have been able to write a script that adds demographs together to create a new demograph e.g. M18+ and F18+ = A18+ which works perfectly however when trying to create a script that will create a demograph range e.g. A18-24, i am encountering some issues i cannot resolve.
My first script that adds two demographs together is as follows:
create table #SurveyTemp
(
Com nchar(6),
Survey nvarchar(50),
Demo nchar(50),
Wk int,
Time int,
Aud decimal(18,8)
);
insert into #SurveyTemp (Com, Survey, Demo, Wk, Time, Aud)
select Com, Survey, 'A18+', Wk, Time, sum(Aud)
from table_survey
where survey = 'LO2017'
and demograph like 'F18+'
or surveyid = 'LO2017'
and demograph like 'M18+'
group by Com, survey, Wk, Time:
insert into table_survey
select temp.Com, temp.Survey, temp.Demo, temp.Wk, temp.Time, temp.Aud
from #SurveyTemp temp
drop table #SurveyTemp
This script works fine. It adds two demographs together and inserts new rows of data, creating a sum of the audience for each Com, Survey, Wk, and then Time. See the sample data set below where the addition of M18+ and F18+ has created a new record called A18+
Let me start with a sample data set: (Disclaimer: the live database has MANY rows for each demograph)
com | surveyid | demo | wk | time | audience
-------------------------
1 | LO2017 | A18+ | 1 | 300 | 4.7
1 | LO2017 | F18+ | 1 | 300 | 1.9
1 | LO2017 | M18+ | 1 | 300 | 2.8
1 | LO2017 | A25+ | 1 | 300 | 2.3
1 | LO2017 | A18+ | 2 | 100 | 3.7
1 | LO2017 | F18+ | 2 | 100 | 1.9
1 | LO2017 | M18+ | 2 | 100 | 2.8
1 | LO2017 | A25+ | 2 | 100 | 4.3
What I need to write now is a script that creates a range. Notice how in the table above there is a A18+ and a A25+. Please bear in mind that in my live table there will be MULTIPLE rows for all demographs.
In this example, I will be using the above table. So, I need to create a similar script that will sum the audience for two demographs and then subtract one from the other to create a range. For example, subtract the A25+ data from A18+ to create a range called A1824. I hope that makes sense.
In the script below, I am trying to create a range called 'A1824' but I am either getting a "subquery returned more than 1 row" error OR it is inserting the wrong data into the temp table where the sum in AudOne and AudTwo is the SAME for every single Wk and Time.
create table #SurveyTemp
(
Com nchar(6),
Survey nvarchar(50),
Demo nchar(50),
Wk int,
Time int,
Aud decimal(18,8),
AudOne decimal(18,8),
AudTwo decimal(18,8)
);
insert into #SurveyTemp (Com, Survey, Demo, Wk, TimeBlock, Aud, AudOne, AudTwo)
(select Com, Survey, 'A1824', Wk, Time, 0.0,
(select sum(aud) from table_survey where demo = 'A18+'),
(select sum(aud) from table_survey where demo = 'A25+')
from table_survey
where surveyid = 'LO2017'
group by Com, survey, Wk, Time,
)
update #SurveyTemp
set Aud = AudOne - AudTwo;
insert into table_survey
select temp.Com, temp.survey, temp.demo, temp.Wk, temp.Time, temp.aud
from #SurveyTemp temp
drop table #SurveyTemp
It is this second script that i need to get working and have spent hours trying to resolve without much luck. Please let me know if i can provide any more information to help you help me!
Edit: My expected results would be something like the following:
com | surveyid | demo | wk | time | audience
-------------------------
1 | LO2017 | A1824 | 1 | 300 | 2.4
But there would be multiple rows where there are multiple 'wk' and 'time' entries. E.g.:
com | surveyid | demo | wk | time | audience
-------------------------
1 | LO2017 | A1824 | 1 | 100 | 2.4
1 | LO2017 | A1824 | 1 | 200 | 3.7
1 | LO2017 | A1824 | 2 | 100 | 2.1
1 | LO2017 | A1824 | 2 | 200 | 6.2
