We have a table of students with fields for the ID of the school district and their school name. For example:
DistrictID
StudentName
SchoolName
10001
John Smith
Washington Elementary
10001
Jane Smith
Lincoln Middle
10002
David White
Hill High
...
...
...
I want is a listing with the school district ID, the student name, and the number of schools in the district.
I believe the following statement should give me what I want:
SELECT DistrictID, StudentName, COUNT(DISTINCT SchoolName) OVER (PARTITION BY DistrictID)
FROM StudentData
However, I get the error:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'distinct'.
If I take out the DISTINCT it runs fine, however it counts all the rows as expected, which is not what I want.
If I remove the OVER clause it runs fine, however, it counds the schools across all the districts, which is not what I want.
I can remove the OVER clause and use GROUP BY, but not while also retrieving StudentName.
The SQL 2005 Online Books don't seem to indicate that my statement is invalid. Here are the links just for reference:
Count: http://msdn2.microsoft.com/en-us/library/ms175997.aspx
Over: http://msdn2.microsoft.com/en-us/library/ms189461.aspx
Anyone have an idea one what I'm doing wrong or how to go about getting this information?
Thanks!

I have 2 tables. Product, ProductCategory. Product table consists of (productid, productname, producttypeid, createdate, portid) productcategory consists of (productid, categoryid, productcategoryid, categoryid, prodroletypeid, createdate) I want to write sql query to get the unique products. So the count should only give one value/resuls. But when I run the following query, I am getting more than one rows select count(distinct categoryid) as uniquecat from productcategory as pc, product as p where pc.prodroletypeid in ('P', 'F') and pc.createdate <= dateadd(d, 30, getdate()) and p.portid = 100 group by pc.productid
when i try to run this following query, i get an error message:
Microsoft OLE DB Provider for SQL Server error '80040e14'
The ntext data type cannot be selected as DISTINCT because it is not comparable.

hello, i have a working stored procedure SELECT CommentID, UserName, PictureID, DateCommented, COUNT(CommentID) OVER (PARTITION BY PictureID) AS 'NrOfComments' FROM Comments WHERE PictureID = @PictureID witch returns among others the number of comments for a picture i need to select the number of distinct users who commented that user too, so i added this at SELECT statement, COUNT(DISTINCT UserName) AS 'Expr1' i get that error: "Colum 'Comments.CommentID' is invalig in the select list beacuse it is not contained in either an aggregate function or the GROUP BY clause." what should i do, to select the number of distinct users who commented on a specific picture? here are the table rows, if you need that CommentID --- UserName --- PictureID --- DateCommented please help me, thank you
I am doing a distinct count on a related table's column, but get an out of memory error if I run it for the entire table (works great for just a few rows when filtered down).The error I get is: "We couldn't get data from the external source.The operation has been cancelled because there is not enough memory available for the application. If using 32-bit version of the product consider upgrading.
I know I can add a related column and that works fine...but that seems to me like I've defeated the purpose, I have a good and proper lookup table, and should be able to run my query against its relationship.Here is the query and details below *Note I supplied a scaled down sample, on my actual model I receive these errors, not in the sample as it has only a few rows
List Workers Distinct Project Customers:=CALCULATE(DISTINCTCOUNT(Projects[CustomerID]),'WorkersToProjects') Other measure which returns no errors, but included for completeness: List Workers Projects:=CALCULATE(DISTINCTCOUNT([ProjectID]),ISBLANK(WorkersToProjects[ProjectID])=FALSE())
My goal here is to allow the user to view the workers assigned to a project, but also get counts of the workers assigned to the CUSTOMER of a project. For example, suppose we lose a customer, we want to see how many workers would be impacted by that, so a count of projects per worker is not useful there, we need to see a count of workers per project's customer (owner of project whom project work is being done for)The question being: How can I accomplish this:
1. WITHOUT adding a calculated column to WorkersToProjects (of Projects.CustomerID) 2. WITH better performance?
There must be a better way to write this DAX to still get the correct answer?*Pic of pivot table, again, the numbers are accurate but the formula used to List Workers Distinct Project Customers measure does NOT scale :( 3 count for red , the number of Projects John has and 2 count for blue, the unique customers/owners of those projects "Veridian Dynamics" and "Massive Dynamic".

sometimes, when tables are poorly joined, we have exactly same rows as a result.. so we use distinct.. but how can we count(*) the distinct rows?
select distinct d.docrefid from tbljobDocuments d left join tbljobitems j on j.docrefid=d.docrefid where d.docrefid='DC01C06027' and j.itemid='39J1667-H86700'
will return me
docrefid DC01C06027
but when i try to count(*) only the distinct record, it count all..
select distinct d.docrefid, count(*) from tbljobDocuments d left join tbljobitems j on j.docrefid=d.docrefid where d.docrefid='DC01C06027' and j.itemid='39J1667-H86700' group by d.docrefid
select a.patientid, a.providerid from PatientDrugList a JOIN Admin..Loadinstance b on a.intLoadInstanceId = b.intLoadInstanceId where a.MailReasonTypeId = -1 and b.SubClientId = 22 and b.StatusTypeId > 0
Now how could I get distinct patientid count and distinct providerid count
I have a table which stores the shift information for employees. The table contains 10 columns as Employeename,Employeeno,month,year,shifttimings etc. If an employee works a day in a particular shift, then a row will be inserted in to the above table for that employee.
Now at the end of the month i wanted to calculate the shift details for each employee for a particular month of a given year like employeename,employeeno, noofdays(countof shiftdays).
I have an SQL statement that looks like the following:
SELECT [Docs-Entities].entityID, entityName, COUNT([Docs-DocsEntities].filename) AS numDocs FROM [Docs-Entities] LEFT JOIN [Docs-DocsEntities] ON [Docs-Entities].entityID = [Docs-DocsEntities].entityID GROUP BY [Docs-Entities].entityID, entityName
but the problem is that numDocs (the COUNT) is not returning a distinct count. In the DocEntities table, a particular document can actually have multiple entries with the same entityID so that produces inflated numbers for numDocs. But when I do a SELECT DISTINCT on a particular entityID, the results are less and don't match the numDocs number because I only need to list the document one time. This is not a huge issue, but it looks bad on my site.
Is there a way that I can make COUNT count distinctly?
Thanks for the help and I hope I worded that cllearly...

I am using MS SQL 2005 and above table is a big table (approx 10 million records)
It doesn't seem possibly, but maybe? Is there a way to have an expression be used, but also benefit from using distinct on a column?
I'm looking for something like: sum(case when dtEntered > '1-1-2006' then 1 else 0 end) but also encorporating somehow a distinct count on UserName. So a username showing twice would only count once, and this would only be counted if the record's dtEntered date was greater than Jan 1, 2006.
The reason I'm writing the statement that way is because there are 5 columns which aggregate data by different time periods.
If it's not possible, I will just end up joining to the table multiple times, putting the date filter in the where clause.
I am trying to get the below query to work and can't seem to get past this error. Not sure but everywhere I look I think my syntax is right. I am probably missing something obvious but I'm just back from vacation and trying to get in the swing of things. Any help would be appreciated.

I want to build query to return how many rows are in this query:select distinct c1, c2 from t1But SQL won't accept this syntax:select count (distinct c1, c2) from t1Does someone know how to count multiple distinct columns?

I have a table of users and date when they logged on to a system. I am trying to count how many distinct users logged on for each day of the week. The SQL below works when there's at least a user for each day. But when there is no user for a particular day such as Sunday, I still want it to return "SUN
0 "
I learned that you can use GROUP BY ALL and it works but the "ALL" is deprecated beyond SQL 2005.
------------------------------------ SELECT UPPER(LEFT(DATENAME(dw, StartTime), 3)) AS DayOfWeek, COUNT(DISTINCT UserID) AS NumberOfUser
FROM testUserLoginDuration WHERE Archived = 0 GROUP BY UPPER(LEFT(DATENAME(dw, StartTime), 3)) ORDER BY CASE WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'MON' THEN 1 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'TUE' THEN 2 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'WED' THEN 3 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'THU' THEN 4 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'FRI' THEN 5 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'SAT' THEN 6 WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'SUN' THEN 7 END
Here is my dataset used by my report definition. The combo of barcode and order id is unique. The 'isDiscountedItem' field indicates if the customer used a coupon to purchased an item at a lower price.
I want to group my report by department id, class id and barcode. Then, I want to count all distinct order ids for which there was at leat one discounted item.
My report would produce the following output considering the above dataset:
Merchandise Number of customers who used a coupon -------------------------------------------------------------------------------------------------------------- Department 1 2
Class 1 2
Barcode 123 2 Barcode 789 1 Department 2 0
Class 7 0
Barcode 456 0
I've been looking at a possible solution using hash tables defined in the report code but I would like to find a 'cleaner' solution. Any help would be appreciated.
Thanks for taking the time to read my post. I greatly appreciate it!

Let's say i want to return distinct count of accounts within a 2-month rolling period meaning in February, i'd get a distinct count for accounts in January & February, then in March i'd get a distinct count for February & March, then in April i'd get it for March & April, and so on... my results table would like the table below:
Account Month
3 1
4 2
5 3
5 4
5 5
I had asked this before but it was a summing equation and not a unique count. I've tried to play with the summing equation to kind of make it work, but i'm starting to get a headache. It's probably so simple!

I need to get the groupwise distinct count . For eg. Lets assume we have group as Category and under this there are two childs Category1 and Category2. I need the distinct count under Category1 and Category2 separately with the count resetting after Category1 and Category2. Any help will be greatly appreciated.
