Using Distinct And Count (*) Is Not Giving The Results Expected
Feb 12, 2008
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

I have just added a third table to a query and I am no longer gettingthe results I am expecting.Three Tables:CUSTINVOICEJOUR (Header Table)CUSTINVOICETRANS (Line Item Table)MARKUPTRANS (Additional Header Info)CUSTINVOICEJOUR has a one to many relationship to CUSTINVOICETRANS.CUSTINVOICEJOUR has a one to many relationship to MARKUPTRANS.I need to sum an integer column from MARKUPTRANS, in rows that arerelated to CUSTINVOICEJOUR, and include that output with my querybelow, which right now has a row for each CUSTINVOICETRANS record:SELECT CUSTINVOICEJOUR.INVOICEAMOUNT, CUSTINVOICETRANS.QTYFROM CUSTINVOICEJOUR INNER JOINCUSTINVOICETRANS ON CUSTINVOICEJOUR.INVOICEID =CUSTINVOICETRANS.INVOICEIDWHERE (CUSTINVOICEJOUR.DATAAREAID = 'acm') AND(CUSTINVOICETRANS.DATAAREAID = 'acm')The above works fine - a row for each record in CUSTINVOICETRANS withthe header info in there as well.I tried the query below to add a SUM() from MARKUPTRANS, but when I runit, I get one row with strange results in it - not what I expected.What am I doing wrong?SELECT CUSTINVOICEJOUR.INVOICEAMOUNT, CUSTINVOICETRANS.QTY,SUM(MARKUPTRANS.VALUE) AS FreightValueFROM CUSTINVOICEJOUR INNER JOINCUSTINVOICETRANS ON CUSTINVOICEJOUR.INVOICEID =CUSTINVOICETRANS.INVOICEID INNER JOINMARKUPTRANS ON CUSTINVOICEJOUR.RECID =MARKUPTRANS.TRANSRECIDWHERE (CUSTINVOICEJOUR.DATAAREAID = 'acm') AND(CUSTINVOICETRANS.DATAAREAID = 'acm') AND (MARKUPTRANS.DATAAREAID ='acm')GROUP BY CUSTINVOICEJOUR.INVOICEAMOUNT, CUSTINVOICETRANS.QTY,MARKUPTRANS.MARKUPCODEHAVING (MARKUPTRANS.MARKUPCODE = 'Freight')

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'm reading a lot of data from a database using SqlDataReader. Now I'd like to report the progress to the user, but for this I need to know in advance how many items SqlDataReader will return.
Is there any way to get this 'number of expected results' from the SqlDataReader?

Hi All,
I am kindly seeking for help.
I have a table(MyTable) which is defined as (date datetime, ID char (10), and R, P,M,D&Y are all float) and the layout is as following:
Date ID R P M D... Y
1/1/90 A 1 2 3 4... 5
1/2/90 A 2 3 4 5... 1
...
2/11/05 A 3 4 5 6... 2
1/1/90 B 1 2 3 4... 5
1/2/90 B 2 3 4 5... 1
...
2/11/05 B 3 4 5 6... 2
...
The expected query results look like: ( this results from Date, ID and R fields)
Date A B
1/1/90 1 1
1/2/90 2 2
...
2/11/05 3 3
The SQL I wrote:
select date, ID,
A=sum(case when ID=A then R else 0 end),
B=sum(case when id=B then R else 0 end)
from MyTable
Group by date
I would also like to get another set of results with the same format but from date,ID and P fields:
Date A B
1/1/90 2 2
1/2/90 3 3
...
2/11/05 4 4
select date, ID,
A=sum(case when ID=A then P else 0 end),
B=sum(case when id=B then P else 0 end)
from MyTable
Group by date
The problem with that is if I have thousands of ID in MyTable I have to "hard code" thousands times and the same problem with the fields/columns. Is there any easier way to do this?
I also would like to insert the results into a table/view which will be refreshed whenever MyTable gets updated.
Any suggestion/comments are highly appreciated!

I have a view over 5 tables that has started giving unreliable results. There are three records that should be different, but in a production Access database, the view is giving three identical records where there should be three unique records. I have tested the view within SQL Server Management Studio and it gives the correct records there. But, I have attached this same view into the same Access database with two separate names. One instance of the view within Access database gives the correct records, and the other gives the incorrect (duplicated) records. I have attached screen shots that show these two separately named incarnations of the same SQL View, with the duplicated data, or the unique data highlighted.
I have also included the SQL query specs for this view.
what I can do to this view in order for it to always give us the unique records that we need, rather than sometimes the correct records, and sometimes the incorrect records.
Correct 3 records:
Incorrect 3 records:

I have the following SELECT statement attached to a dropdown box:
SELECT [Workshop] FROM [Workshops] WHERE Workshop <> (SELECT Workshop FROM Workshop_Registration WHERE FullName = @FullName AND Completed = @Completed) ORDER BY [Workshop]
I am trying to get all workshops (50 or more) from the WORKSHOPS table that the logged in user is not already registered for. This works perfectly as long as the student is registered for at least 1 class. It populates the dropdown with all of the other classes. If they aren't registered for a class then it doesn't list any classes. The problem is definitely the subquery, but how do I make it to where if the subquery doesn't return any results (student not registered for anything), I get all of the workshops in the dropdown? Any help is appreciated!

Hello,
My full-text search isn't working at all! I have a temporary table with full-text indexing enabled where files are scanned for social security numbers. If it has one, the user will see a message that it believes it's found a SSN and won't upload it. There is only ever one row in this table, as we overwrite the contents upon each upload.
I'm testing this search, and it doesn't work. The table has the following columns:
attachemtId (int) - primary key
fileContent (image) - contents of the file
fileExtension (varchar) - extension of the file (this is always either ".pdf" or ".doc")
I created a .doc file that simply says "ssn", and then run the following query:
SELECT * FROM TempAttachment
WHERE CONTAINS(fileContent,'ssn')
and nothing is returned! I tried the same thing with a .pdf file, and same results.
I'm not sure if this is related, but earlier I had this issue where I had to reset permissions for the directory. I've tried removing the full-text index and adding it again, but that didn't do anything. I also checked error logs on the server, and there were no messages. Any help would be appreciated! Thank you!

We can use comparison operators with strings as well. Hence, I tried to use the following query on a SQL Server 2012 instance with the sample AdventureWorks2012 database (the collation of the database and of the column is the default:
SQL_Latin1_General_CP1_CI_AS):
USE AdventureWorks2012 ;
GO
--Returns 5 records
SELECT pp.Name
FROM Production.Product AS pp
WHERE pp.Name >= N'Short' AND pp.Name <= N'Sport' ;
GO
The query only returns 5 records. This despite the fact that the search is an inclusive search and the Production.Product table contains records that begin with "Sport".
Now, when I replace "Sport" with "Sporu" (just moving one character up in the alphabet to verify whether characters after the word have any impact on the search) gives me 8 records.
USE AdventureWorks2012 ;
GO
--Returns 8 records
SELECT pp.Name
FROM Production.Product AS pp
WHERE pp.Name >= N'Short' AND pp.Name <= N'Sporu' ;
GO
What's going on inside of SQL Server that allows it to fetch "Short-Sleeve Classic Jersey" for the starting word "Short" but prevents it from fetching "Sport-100 Helmet" for the ending word "Sport" despite the search being an inclusive search?

hi all,
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
will return me
DocrefId Count
DC01C060272
when i expect
DocrefId Count
DC01C060271

I am trying this query:
select * from Mytable where
contains(MyColumn, '123.345.')
I gues the contains would return all the rows with column contains 123.345, but this does not return all the expected rows, only one row.I have tried to replace "." with "-" but the result is the same.I have also tried with '123.345.*. In this case I have got more results, but no all the exptected rows.If I use this query:
select * from MyTable where

Here's one thats had me and a coworker puzzled. Hopefully it's something simple:

Table A Data:

1, 6/18/2008 @ 2:31:02, This is my message
1, 6/17/2008 @ 7:34:26, This is another message
2, 6/18/2008 @ 2:32:41, This is not his message
2, 6/16/2008 @ 11:21:32, This is my message
TABLE B: (List of users)
userid, int
name, varchar(100)
Table B Data:
1, John
2, Mike
I want to extract the most recent message logged per user, i.e.:
name | date | message
--------|---------------------|-------------------------
John | 6/18/2008 @ 2:32:41 | This is my message
Mike | 6/18/2008 @ 2:32:41 | This is not his message.
I have been unable to come up with a query that can return just the one value. I've tried variants of:
SELECT DISTINCT b.name, a.date, a.message
FROM a INNER JOIN
b ON a.userid = b.userid
including sub-queries and even played with the visual diagrams trying to design this in Enterprise Manager but none of the combinations I tried work. Is there an easy way to do this via a query? I don't have experience with stored procedures. Would that be necessary?

Hello, first post since I can usually find answers by reading the forums. I've searched the internet up and down and for some reason I can't get this query to work properly.
I have two tables:
ticket
ticket_id
ticket_to
ticket_from
message
message_id
ticket_id
message
There can be several messages per ticket, connected by the ticket_id. I'd like to only pull only the most recent message, as well as the results from the ticket table. Currently I'm getting all messages per ticket.
Here's what I have:
SELECT distinct ticket.ticket_to, ticket.ticket_from, message.ticket_id, message.message
FROM tickets
INNER JOIN message ON tickets.ticket_id = message.ticket_id
GROUP BY message.ticket_id, message, ticket_to, ticket_from
Any help would be greatly appreciated! Thanks much.

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...

Hi,
I want a count of distinct rows in a table through a single query -- is it possible?
eg.
table-
create table ch1 (a int, b int, c int, d int)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,3,4,5)
Here distinct row count in a table is 3 which I want to achieve thro a query.
if I do
select count(distinct a) from ch1 it works fine and gives me output as 2.
but this is not working
select count(distinct a,b,c,d) from ch1 - any workaround to find the distinct row count in a table??
Please reply.
Cheers!

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.
