I need to get unique records from table and get their count of recurrence. I have query:
SELECT AwardReference.ownerID
FROM AwardReference
WHERE AwardReference.ownerType = 'song';
This returns something like:
ownerID
1
2
4
4
5
5
5
I need do get something like:
ownerID count
1 1
2 1
4 2
5 3
Does anyone knows how to do it?
Also I have to do this task with MS ACCESS...
SELECT AwardReference.ownerID ,
COUNT(*) AS count
FROM AwardReference
WHERE AwardReference.ownerType = 'song'
GROUP BY AwardReference.ownerID

The table itself is more complex and larger. But the point is this. How can this be done? And I can't know in advance the ID numbers of the first column.
SELECT T.ID,SUM(T.KWH)SUM_KWH
FROM YOUR_TABLE T
GROUP BY T.ID
Do you need this one?
Let's assume your database name is 'testdb' and table name is 'table1'.
SELECT * FROM testdb.table1;
SELECT id, SUM(kwh) AS "kwh2"
FROM stack.table1
WHERE id = 1
keep running the query will all (ids). you will get output.
By following this query you will get desired output.
Hope this helps.
There is a table with values as below,
Id Value
1 1
2 1
3 2
4 2
5 3
6 4
7 4
now need to write a query to retrieve value from the table and output should look as
ID Value
1 1
3 2
5 3
6 4
any suggestion ?
The query you want is nothing to do with being distinct, it's a simple aggregation of value with the minimum ID for each:
select Min(id) Id, value
from table
group by value
I'm attempting to have a function or view that is able to calculate and roll up various counts while being able to search on a many to many affiliation.
Here is an example data set:
Invoice Table:
InvoiceID LocationID StatusID
1 5 1
2 5 1
3 5 1
4 5 2
5 7 2
5 7 1
5 7 2
Group Table:
GroupID GroupName
1 Group 1
2 Group 2
GroupToLocation Table:
GroupToLocationID GroupID LocationID
1 1 5
2 2 5
3 2 7
I have gotten to the point where I could sum up the various statuses per location and get this:
LocationID Status1 Status2
5 3 1
7 1 2
Location 5 has 3 Invoices with a status of 1, and 1 invoice with a status of 2 while Location 7 has 1 status 1 and 2 status 2
There are two groups, and Location 5 is in both, while Location 7 is only in the second. I need to be able to set it up where I can append a where statement like this:
select * from vw_GroupCounts
where GroupName = 'Group 2'
or
select Invoice, SUM(*) from vw_GroupCounts
where GroupName = 'Group 2'
And that result in only getting Location 7. Whenever I do this, as I have to use left joins or something along those lines, the counts are duplicating for each group the the Location is affiliated with. I know I could do something along the lines of a subquery and pass in the GroupName into that, but the system I am working with uses a dynamic query builder that appends WHERE statements based on user input.
I don't mind using view, or functions, or any number of functions inside of functions, but I hope there is a way to do what I'm looking for.
Since locations 5 and 7 are in Group 2, if you search for group 2 in the where clause after joining all the tables, then you would get all records in this case, this isn't duplication, just the way the data is. A different join wouldn't change this, only changing the data. Let me know if I am misunderstanding something though.
Here is how you would join them to do that search.
Here it is with your first example of the location and status count.
I have two tables:
Report
ReportId CreatedDate
1 2018-01-12
2 2018-02-12
3 2018-03-12
ReportSpecialty
SpecialtyId ReportId IsPrimarySpecialty
1 1 1
2 2 1
3 3 1
1 2 0
1 3 0
I am trying to write a query that will retrieve me the last 10 reports that were published. However, I need to get 1 report from each specialty. Assume there are 100 specialties, I can pass in as an argument any number of specialties, 10, 20, 5, 2, etc...
I'm trying to figure out a way where if I send it all specialties, it will get me the last 10 reports posted based on the last date created, but it won't give me 2 articles from same specialty. If I send it 10 specialties, then I will get 1 of each. If I send it 5, then I'll get 2 of each. If I send it 3 then I'll get 4 of 1 and 3 of other two.
I may need to write multiple queries for this, I'm trying to see if there is a way to do this on the SQL side of things? If there isn't, then how would I break down to multiple queries to get the result I want?
What I have tried is this, however I get multiple reports with same specialties:
SELECT TOP 10 r.ReportId, rs.SpecialtyId, r.CreatedDate
FROM Report r
INNER JOIN ReportSpecialty rs ON r.ReportId = rs.ReportId AND rs.IsPrimarySpecialty = 1
GROUP BY rs.SpecialtyId, r.AceReportid, r.CreatedDate
ORDER BY r.CreatedDate DESC
with cte as (
SELECT R.ReportId, R.CreatedDate, RS.SpecialtyId,
ROW_NUMBER() OVER (PARTITION BY RS.SpecialtyId
ORDER BY R.CreatedDate DESC) as rn
FROM Report R
JOIN ReportSpecialty RS
ON R.ReportId = RS.ReportId
AND RS.IsPrimarySpecialty = 1
WHERE RS.SpecialtyId IN ( .... ids ... )
)
SELECT TOP 10 *
FROM cte
ORDER BY rn, CreatedDate DESC
row_number will create a id for each speciality, so if you pass 3 speciality you will get something like this.
rn speciality_id
1 1
1 2
1 3
2 1
2 2
2 3
3 1
3 2
3 3
i have mssql tabel like this >
ID Code Rating
1 10 4
2 10 5
3 10 4
4 11 2
5 11 3
The sql query logic i want ...
I want when i search the record using code 10 then the output would be 4 because the 4 rating would be given most of the time for code 10 ....
and another logic if i search for code 11 then the out put will be 3 because 3 will be most recent rate for code 11...
how to write the sql query for im using ASP.NET ( VB)
The first thing you want to do is filter:
SELECT * FROM mytable WHERE Code = 10
You're interested in the 'rating' field:
SELECT Rating FROM mytable WHERE Code = 10
Now you want to count entries for Rating, which can be achieved using a combination of GROUP BY and the COUNT() function:
SELECT COUNT(*), Rating FROM mytable WHERE Code = 10 GROUP BY Rating
Now all that's left is sort by count, descending, and select only the first row:
SELECT TOP 1 Rating FROM mytable WHERE Code = 10 GROUP BY Rating ORDER BY COUNT(*) DESC
