When Does Ssrs Use A DISTINCT Clause In It's Queries?
Jun 27, 2007
I am having a heck of a time figuring out what controls how/when the generated SQL for a report puts a DISTINCT clause in front of it.
For instance, not that this report makes any sense, but I have 58 rows in my fact table/entity €“ If I pull in a lookup field and execute, the distinct is put in the query and I basically get a list of the possible domain values. It runs the whole joined table query to get them, but it does list (in this case) just 4 records. Now I put in the primary ID of the fact entity and the distinct goes away and I get my 58 rows. If I put two lookup fields, the DISTINCT is back. If I pull in the description field (text string just a direct source field mapping not part of the identifying attributes), the distinct is there. If I pull in the Company Name field on a different entity (which is essentially the same as pulling in Description only it is part of the identifying attributes), there is no DISTINCT. I can pull in all my fields on this entity and none of them drive the distinct. And I swear (ok, I am probably lying but not on purpose) the field/attribute and roles properties are all the same on the attributes. But you get my general question/situation...
Any insight for me? Does it have to do with how I am building the report rather than the underlying model?
Thanks in advance,

I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?

Hi,I have a table that contains log data, usually around a million records. Thetable has about 10 columns with various attributes of the logged data,nothing special. We're using SQL Server 2000.Some of the columns (for example "category") have duplicate valuesthroughout the records. We have a web page that queries the table to showall the unique columns, for example:select distinct CATEGORY from table TESTObviously the server has to scan all rows in order to get all unique columnswhich takes quite a while, especially since that web page contains severalof these types of queries. We also have a MAX(DATE) and MIN(DATE) query thatalso add to the load.I already created indexes on the CATEGORY (actually on all categories)column which might help a little but I'm pretty sure that there has got tobe a better way.I also create a view (select distinct CATEGORY from table TEST) and tried toindex it, but it won't let me index a query that contains a DISTINCTstatement.Isn't there a way to create an index that contains only the distinct values?Is there another way to speed this up?Thanks for any hints!

Hello,
I was wondering if anyone can explain the positives and negatives of using a single stored procedure that contains one or more distinct queries. I know there are problems with dynamic SQL but I am not proficient enough to know whether this falls under that umbrella.
For clarification, what I am referring to is this: In a single stored procedure, I have a parameter called Query_ID that is used to identify which query in the sproc that I want to execute. Then from my ASP page, I simply pass the appropriate value for Query_ID. So:
IF @QUERY_ID = 1
BEGIN
SELECT [whatever]
FROM [tbl1]
WHERE [conditions]
GROUP BY [something]
ORDER BY [somethingelse]
END
ELSE
IF @QUERY_ID = 2
BEGIN
SELECT [whatever]
FROM [tbl2]
WHERE [conditions]
GROUP BY [something]
ORDER BY [somethingelse]
END
END
I hope that makes sense. Thanks in advance.

Hi,
I wonder if its possible to perform a ORDER BY clause in an SELECT DISTINCT sql query whereby the AS SINGLECOLUMN is used. At present I am recieving error: ORDER BY items must appear in the select list if SELECT DISTINCT is specified. My guess is that I cant perform the Order By clauses because it cant find the columns individually. It is essentail I get this to work somehow...
Can anyone help? Thanks in advance

Hi Guys,
I am having trouble with a particular query that is beyond my scope of understanding.
Basically I need to pull sales records based on the following criteria:
I have CustomerID, InvoiceNumber, ContractEndDate, MobileNumber, etc..
Customers recontract their mobile phone plans through us, and we have a new sales record for each time they recontract.
For example, CustomerNumber 123 has recontracted 3 times..
once on 2006-01-01, then on 2007-02-12, and finally on 2008-02-15..
So they have a 12 month contract each time.. then come in to recontract it.
So.. a customer has a single Customer Detail record, but may have many sales records attached. And a customer may have several sales for the SAME mobile phone number.
Currently to pull ALL sales records for all customers, my query is this:
Code:
SELECT xxx.CustomerID AS xxx_CustomerID,
xxx.Invoice AS xxx_Invoice,
yyy.PhoneType AS yyy_PhoneType,
yyy.PlanType AS yyy_PlanType,
yyy.ContractEnds AS yyy_ContractEnds,
yyy.MOB AS yyy_MobileNumber
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE yyy.ContractEnds IS NOT NULL
AND xxx.CustomerID IS NOT NULL
We want to get a list of customers that we can call to recontract, based on the ContractEnd field.
However, we want UNIQUE mobile phone numbers, with the LATEST ContrtactEnd date.
So, Customer 123 has 6 sales, for 2 unique Mobile numbers, the sql may be like:
Code:
SELECT MAX(yyy.ContractEnds) AS LatestCED, yyy.MOB
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE xxx.CustomerID='123'
GROUP BY yyy.MOB
Now, this works fine, and of course if i remove the WHERE clause, it collects all unique mobiles, with latest ContractEnd date for each, for all customers. (Customer 123 displays 2 mobile numbers, each with the LATEST ContractEnd date)
BUT i need this information ALONG WITH the other fields (xxx.CustomerID, xxx.Invoice, yyy.PhoneType, yyy.PlanType) and i have tried a few ways of doing it, but can't get my head around it..
Keep getting errors about Aggregate functions and Group By clause, and i understand why i am getting them, just cant think of any alternative query.
Can anyone please help me!
Thanks guys,
Mick

I have integrated sharepoint list data to SQL Server reporting services. I am using the below to query sharepoint list data using sql reporting services.
<Query>Â Â <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>Â Â
<Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems">Â Â Â Â Â
<Parameters>Â <Parameter Name="listName">Â Â Â Â Â Â Â
[Code] .....
By using this query, I am getting a dataset which includes all the columns of sharepoint list. Among these columns, I wanted to display only 2 columns (i.e Region and Sales type) using chart. I have created a Region parameter but when I click preview, the drop down box is giving me all the repeatative values of region like
RG1,RG1,RG1,RG2,RG2,RG2,RG2,RG3..........
I wanted to display only distinct values of Region parameter so that whenever end user select region from the parameter drop down, it will display the respective value of Sales type column.Also when I select only RG1 parameter, it is giving me a chart including the sales type of all the Regions. (it should display me only the sales type of RG1) How can I link these 2 columns so that they will display the values respectively. Â

Is there a way to stop SSRS from rewriting my SQL? I can write an SQL statement that will execute within seconds within SQL Server Management Studio. But when I put that SQL into a dataset in SSRS, SSRS rewrites the SQL and makes the WHERE clause much more complex. Now the SQL takes minutes to complete.
Is there a way to stop this?

I have below query which is working fine in SQL but if i use same query in SSRS dataset then it is not working at all.If i put only one condition in where clause then it works but if i put multiple conditions then it does not works in SSRS and through error "data is not available".
SELECT id,
DATEDIFF(DAY, Created, BMTRequestReviewDate) AS 'EvaluateDays',
all code goes here
FROM [dbo].[SBWT_Data]
WHERE
upper(Status) not like '%XX%'
AND upper(Status) not like '%DELETED%'
upper(Status) not like '%CLOSED%'
---OR
WHERE Status NOT IN ('90 - Closed','XX - Rejected','XX - Request Rejected','XX - Deleted')
As you can see in code i have tried with both where conditions but it is not working. It seems that SSRS does not supports multiple conditions for same field.

I have made an SSRS report using the recursive parent functionality to show a hierarchical tree of values. The problem I have is that some children have more than one parent, but because (in order to use the recursive parent nicely) I need to group the results by Id, I only see distinct entries. This means that I only see each child once, even if it "should" appear in multiple locations in the report (under each of its parents).

Hi, I have the following script segment which is failing:
CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))
INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache
When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."
Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.
The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.
Any ideas?

I need to run a SELECT DISTINCT query acrossmultiple fields, but I need to add another field that is NON-DISTINCTto my record set.Here is my query:SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, genderFROM gpresultsWHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis query runs perfect. No problems whatsoever. However, I need toalso include another field called "admitdate" that should be treatedas NON-DISTINCT. How do I add this in to the query?I've tried this but doesn't work:SELECT admitdateFROM (SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, gender from gpresults)WHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis has to be simple but I do not know the syntax to accomplishthis.Thanks

Hello,
I have written a small asp.net application, which keeps record of the proposals coming from the branch offices of a bank in a tableCREATEd as a TABLE Proposals ( ID smallint identity(7,1), BranchID char(5), Proposal_Date datetime )
This app also calculates the total number of proposals coming from a specific branch in a given date bySELECTing COUNT(BranchID) FROM Proposals WHERE BranchID=@prmBranchID AND Proposal_Date=@prmDateand prints them in a table (my target table).
This target table has as many rows as the result of the "SELECT COUNT( DISTINCT Proposal_Date ) FROM Proposals"and excluding the first column which displays those DISTINCT Proposal_Dates, it also has as many columns as the result of the"SELECT DISTINCT BranchID FROM Proposals". This target table converts the DateTime values ToShortDateString so that we are able to see comfortably which branch office has sent how many proposals in a given day.
So far so good, and everything works fine except one thing:
Certain DateTime values in the Proposals table which are of the same day but of different hours (for ex: 11.11.2005 08:30:45 and11.11.2005 10:45:30) cause some trouble in the target table, where "SELECT COUNT( DISTINCT Proposal_Date ) FROM Proposals" is executed, because (as you might already guess) it displays two identical dates in ShortDateString form, and this doesn't make much sense (i.e. it causes redundant rows)
What I need to do is to get a result like (in a neat fashion :)
"SELECT COUNT( DISTINCT Proposal_Date ) <<DISTINCT ONLY IN THE DAYS AND NOT IN HOURS OR MINUTES OR SECONDS>> FROM Proposals"
So, how to do it in a suitable way?
Thanks in advance.

I am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
and
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Is it possible to write SSRS 2008 reports to run on an existing SSRS 2005 server?
If yes, what do I need to do to be able to write SSRS 2008 reports on my developer PC that will run on the SQL 2005 Server (which also has SSRS 2005 installed on it)?
I installed Visual Studio 2008 beta on the development PC and it appears that it needs SSRS installed on it too. So I installed SQL 2008 SSRS (SQL Server Reporting Services) and SQL 2008 Workstation Components onto the developer PC. Next I run the SQL 2008 "Reporting Services Configuration" tool. When I click on the "Web Service URL" section it hangs indefinitely and I have to force it closed.
The developer PC is Windows Vista Business.
Any suggestions on making this work, or any other information that you can think of that would allow me to use Visual Studio 2008 and the SQL 2008 "Report Designer Preview" tool to develop SSRS reports that will run on the SQL 2005 SSRS server?
Thanks!

Hi,
What is HAVING clause equivalent in the following oracle query, without the combination of "GROUP BY" clause ?
eg :
SELECT SUM(col1) from test HAVING col2 < 5
SELECT SUM(col1) from test WHERE x=y AND HAVING col2 < 5
I want the equivalent query in MSSQLServer for the above Oracle query.
Also, does the aggregate function in Select column(here the SUM(col1)) affect in anyway the presence of HAVING clause?.
Thanks,
