Select DISTINCT On Multiple Columns Is Not Returning Distinct Rows?

Jul 6, 2007

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?

Compact / Distinct Multiple Columns

Jun 13, 2008

Hi,

I have a table with the following example data

idcol1col2col3
----------------------------
1abcnullnull
1abcnullnull
1null123null
4alphanullnull
4alphanullgamma
1abc987null

I would want to reduce that somehow to
idcol1col2col3
-----------------------------
1abc123null
1abc987null
4alphabetagamma

First thing in my mind was distinct over multiple columns, but I haven't found any resource mentioning that possibility.
I don't immediatly see a way without (complex) looping.
Can anybody put me on the right track?

btw, I know that Id is not an id.
It's a table var that holds an id of a table combined with fields of other tables.

Select Distinct Rows

Mar 19, 2004

Hi,

I'm having a little bit of trouble trying to figure out how to do this query, right now I have:

SELECT I.AppItemId, P.ProductID, P.PartNum, P.Relist, I.AppUserId
FROM ProductsToRelist I join Products P on P.ProductID = I.AppSKU
WHERE P.Relist = 1 and I.AppStatus = 5 and Not I.AppItemId is Null

and it returns something like this:

AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
1665 -30987 SELECT_OOS11
2433 -30987 SELECT_OOS11
4272 -30984 SELECT11
2436 -30984 SELECT11
2793 -32708 SELECT11

But I only it want it to return 1 record for each ProductID like so:

AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
4272 -30984 SELECT11
2793 -32708 SELECT11

ProductID is the primary key for the Products table, and a product can be in the ProductsToRelist table many times but each row would have a unique AppItemId. I know that I need to use Distinct or a different kind of join, but I'm not sure which. How would you suggest to do this?

Thanks

Select Distinct For Different Rows

Jun 5, 2006

I have the following tablecolumns: [col1], [col2],[col3] and [NAME].I want to select the name column for each row where [col1]='07'.The problem is that there are several rows where [col1] contains '07' and also the name is the same. [col2] and [col3] contain different data for these double rows...however, I cant use the [col1] and [col2] values in my query because I dont know what values they contain beforehand.So now, when I execute my query and add the DISTINCT key I still get all the double rows!I hope this explains my problem, help is really appreciated...ow, btw: deleting the double rows is not an option....

SELECT DISTINCT - But Just One Of The Selected Columns

Sep 22, 2005

Hi,

I have a table with 3 columns - userID, score, dateCompleted

From this table I wish to select the highest score for each userID and the date for that score. If there is more than one row with the same userID and score (i.e. the user got the same score twice), I want to select the earliest date.

To clarify, there are multiple rows which have the same userID, and may have the same score too, but I want to pull out just 1 score for each userID.

I could do this quite easily if the DISTINCT operator worked on a per column basis, but it works on the entire row instead. Is there a way to SELECT DISTINCT column, but still output other columns in those rows?

I hope this is clear, but please let me know if I've confused you.

Retrieve Distinct Rows From Select Statement

Jan 10, 2014

Is it possible to retrieve Distinct rows from this Select Statement?

I'm getting the correct results, but duplicate rows because some customers place more than one order on the same day.

Code:
SELECT dbo.Customers.CustomerID, dbo.Customers.Title, dbo.Customers.FirstName, dbo.Customers.LastName, dbo.Customers.CustomerEmail, dbo.Customers.DateCreated,
CONVERT(char, dbo.Customers.DateCreated, 103) AS [DD/MM/YYYY], dbo.loyalty_points.LPoints, dbo.Orders.OrderID
FROM dbo.Customers INNER JOIN
dbo.loyalty_points ON dbo.Customers.CustomerID = dbo.loyalty_points.CustomerID INNER JOIN

Select With Multiple Column And Distinct

Jun 22, 2008

Hi guys, I'm hoping there's someone out there with more sql knowledge and experience than me. I'll try to explain everything.

I'm trying to create a select statement but i'm not gettting the required results mainly because i think its a very complicated select.

Here is the scenario.

The table has 12 columns

ProductID Colour MD01 MD02 MD03 MD04 MD05 MD06 MD07 MD08 MD09 MD010

The ProductID is naturally the unique key.

There is always a colour value. But there is not always a value in the MD columns. For example one Product may have values in MD01 MD02 MD03 MD04 MD05 whilst another has values in all MD columns.

My problem is thatI am trying to create a results list based upon selecting distinct values from the colour and md columns

In otherwords i can't have more than only one instance of a word appearing in the recordset list

I'm really struggling with this because there are only 6 colours so if i set distinct purely on 6 colours i only get back 6 rows.

When I try to set disctinct across all the MD columns it seems to ignore it and lists results for example in the table

ProductID Colour MD01 MD02 MD03 MD04 MD05 MD06 MD07 MD08 MD09 MD010
1 red car bike
2 blue bike car train

my select lists results as
red
car
bike
blue
bike
car
train

and it is as if it only carries out the distinct command across the row not across all columns for all rows if you see what i mean?

I need to be able to list all data from all rows that have values in the MD columns and colour column but not list the values more than once and not list "empty" (NULL) columns. Does this make sense?

This is the select statement i wrote.

Select DISTINCT md00, md01, md02, md03, md04, md05, md06, md07, md08, md09, md10, colour FROM TEMPLATES WHERE md00 IS NOT NULL or md01 IS NOT NULL or md02 IS NOT NULL or md03 IS NOT NULL or md04 IS NOT NULL or md05 IS NOT NULL or md06 IS NOT NULL or md07 IS NOT NULL or md08 IS NOT NULL or md09 IS NOT NULL or md10 IS NOT NULL

But it returns empty columns and it returns every instance of the same word so in other words the distinct command doesn't seem to be working at all?

I don't know if this is because of my asp code I am trying to list results with the rescordset?

<%
While ((Repeat1__numRows <> 0) AND (NOT template_rs.EOF))
%>

<%=(template_rs.Fields.Item("md01").Value)%>
<%=(template_rs.Fields.Item("md02").Value)%>
<%=(template_rs.Fields.Item("md03").Value)%>
<%=(template_rs.Fields.Item("md04").Value)%>
<%=(template_rs.Fields.Item("md05").Value)%>
<%=(template_rs.Fields.Item("md06").Value)%>
<%=(template_rs.Fields.Item("md07").Value)%>
<%=(template_rs.Fields.Item("md08").Value)%>
<%=(template_rs.Fields.Item("md09").Value)%>
<%=(template_rs.Fields.Item("md10").Value)%>
<%=(template_rs.Fields.Item("colour").Value)%>

<%
Repeat1__index=Repeat1__index+1
Repeat1__numRows=Repeat1__numRows-1
template_rs.MoveNext()
Wend
%>

I have one more problem. How can I also in addition to being able to list all distinct results list only results for a specific letter

for example

Select DISTINCT md00, md01, md02, md03, md04, md05, md06, md07, md08, md09, md10, colour FROM TEMPLATES WHERE md00 IS NOT NULL or md01 IS NOT NULL or md02 IS NOT NULL or md03 IS NOT NULL or md04 IS NOT NULL or md05 IS NOT NULL or md06 IS NOT NULL or md07 IS NOT NULL or md08 IS NOT NULL or md09 IS NOT NULL or md10 IS NOT NULL WHERE FIRST LETTER ='A'?

I am so far out of my depth here guys I am hoping that someone who has real knowledge of SQL can help me with this statement. I've been pulling my hair out for days now and getting just more and more frustrated listing the same results :(

Trying To Add A NON-DISTINCT Field To A DISTINCT Record Set In A Query.

Mar 12, 2007

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

Analysis :: DAX For Distinct Count Of Related Column Without Returning Out Of Memory Error?

Aug 10, 2015

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".

DISTINCT To ShortDateString, Not DISTINCT To The DateTime; How?

May 8, 2006

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.

Selecting Distinct Rows

Hi,
I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

Forcing Specific Distinct Columns....

Dec 6, 2006

Hi Guys,

I have a slight problem, a query that i have written produces data with 2 primary keys the same... however, DINSTINCT wont work in this case as the rows are still different...

Is their a way to force 1 column to always be unique?

Heres the query:

SELECT TOP 5 ORDER_ITEM.ItemID AS 'Item ID', ITEM.ItemName AS 'Item Name',
(SELECT SUM(OrdItem2.ItemQuantity) FROM ORDER_ITEM OrdItem2
WHERE OrdItem2.ItemID = ORDER_ITEM.ItemID
) AS Total_Purchased, SUM(ORDER_ITEM.ItemQuantity) AS 'Customer Purchased',
CUSTOMER.customerForename AS 'Customer Forename',
CUSTOMER.customerSurname AS 'Customer Surname'
FROM ITEM, ORDER_ITEM, ORDER_T, CUSTOMER
WHERE ITEM.ItemID = ORDER_ITEM.ItemID
AND ORDER_ITEM.OrderID = ORDER_0510096.OrderID
AND ORDER_T.CustomerID = CUSTOMER.CustomerID
GROUP BY ORDER_ITEM.ItemID, ITEM.ItemName,
CUSTOMER.customerForename, CUSTOMER.customerSurname
ORDER BY Total_Purchased DESC

The query is supposed to select the TOP 5 Products sold as well as selecting the customer that purchased the greatest amount of that item and the amount they purchased.

Currently, i will get 2 duplicate rows (except for customers name and the items the purchased. Like this:

ItemID
83630Mathew Smith
8 366Tony Wattage

Which is kinda annoying.... is there anyway i can prevent this?

And also apart from the Where Joins... is there a more efficient way of writing this?

thx for reading :-)
