SSIS Package -Count based on multiple columns - ssis

Question

I need to create an SSIS Package that provides me the count of workdoneby (contractor/company).
Input table from sql server db:
I need to count no of orders by contractor and company for a particular day + station + worktype + accountno.
My output should look like this.
Can someone help me how to create a package to get the desired output?

Answer 1

Since the data is in a table, you can ask the database engine to do the calculation logic.
Setup
I created a temporary table and populated it with the supplied data.
CREATE TABLE
#Source
(
[Date] date
, Station char(3)
, worktype char(2)
, Accountno varchar(10)
, workdoneby varchar(10)
)
INSERT INTO
#Source
(
Date
, Station
, worktype
, Accountno
, workdoneby
)
VALUES
('2018-06-24', 'RMS', 'RH', 'I.145.001', 'Company')
, ('2018-06-24', 'RMS', 'PH', 'I.145.001', 'Contractor')
, ('2018-06-24', 'RMS', 'PH', 'I.145.002', 'Company')
, ('2018-06-24', 'RMS', 'PH', 'I.145.002', 'Contractor');
Query time
Now let's query! I find it is helpful to break these problems down into smaller pieces. The first thing I want to do is break out the workdoneby column into two columns with a 1 or 0
SELECT
S.Date
, S.Station
, S.worktype
, S.Accountno
, CASE S.workdoneby
WHEN 'Contractor' THEN 1
ELSE 0
END AS contractorCount
, CASE S.workdoneby
WHEN 'Company' THEN 1
ELSE 0
END AS companyCount
FROM
#Source AS S
Running that let's me look at the results and see I still have 4 rows and I get the correct entity counted.
The next step is to collapse/summarize/roll-up the values. You indicate we should group by date/station/worktype/accountno so that's exactly what we're going to to do.
I find it easier to debug if I take that first query and make it a derived table so the basic form now becomes SELECT * FROM (ORIGINAL QUERY HERE) AS D thus
SELECT
D.Date
, D.Station
, D.worktype
, D.Accountno
, D.contractorCount
, D.companyCount
FROM
(
SELECT
S.Date
, S.Station
, S.worktype
, S.Accountno
, CASE S.workdoneby
WHEN 'Contractor' THEN 1
ELSE 0
END AS contractorCount
, CASE S.workdoneby
WHEN 'Company' THEN 1
ELSE 0
END AS companyCount
FROM
#Source AS S
) D
Now that you can see it's giving the same original results, we're going to use the SUM function on the contractorCount and companyCount columns and GROUP BY date/station/worktype/accountno
SELECT
D.Date
, D.Station
, D.worktype
, D.Accountno
, SUM(D.contractorCount) AS contractor
, SUM(D.companyCount) AS company
FROM
(
SELECT
S.Date
, S.Station
, S.worktype
, S.Accountno
, CASE S.workdoneby
WHEN 'Contractor' THEN 1
ELSE 0
END AS contractorCount
, CASE S.workdoneby
WHEN 'Company' THEN 1
ELSE 0
END AS companyCount
FROM
#Source AS S
) D
GROUP BY
D.Date
, D.Station
, D.worktype
, D.Accountno;
SSIS
Now that we have data looking as expected, within SSIS you need to do something with it. Your question doesn't specify what you need to do but likely you're going to use a Data Flow Task to push this aggregated data from one place to another destination (different server, Excel, etc) or you're going to push this data into a table on the same server in which case you're going to use an Execute SQL Task
