Ranking
Oct 22, 2007
I was wondering what kind of SQL statement I would need to do the following:
For example I have a table that has an ID (vID) column, product id (vPID) and a timestamp (vTime). What I essentially want to do is go through this table and find the top 10 instances of any vPID. I will illsutrate it below.
- vID vPID vTime
1 25 101012323
2 25 101012323
3 09 101012323
4 25 101012323
5 25 101012323
6 11 101012323
7 25 101012323
8 10 101012323
9 10 101012323
10 25 101012323
11 25 101012323
12 25 101012323
13 25 101012323
14 11 101012323
15 25 101012323
Now what I want to do is return the top vPID instances from highest to lowest so my output should return 25, 11, 10 etc.
I hope what I'm asking made sense to you guys, basically im just looking for the top 10 instances of a any product id (vPID)
Thanks.

Hello All,
I am working on a ranking scenario for a client and I am stumped. Here's the situation...I have an aggregated table that has number of items sold for a salesperson for a given pay period. My client wants to the top 10 salespeople in a report. If two sales people tie, then they should have the same rank, and then the next salesperson in the ranking should have the appropriate number in the sort order. I am trying to figure out how to accomplish with the rank column below.
SalespersonID AmountSold Rank
1 5 1
2 5 1
3 4 3
4 4 3
5 2 5
I need the data in my table to look like the example and I am having a difficult time figuring out how. Any help would be appreciated.
Thanks,
Terry

I have a sales report showing Customer, tons shipped, and sales amount with two parameters: year and month. I want to show the ranking by month by both tons and sales. It is easy enough to sort the results by one of the measures and compute a line number but I can't seem to get the rank function to work to compute the ranking by two different measures.
Any ideas?
Thanks.

I have a table that has several dozen account numbers. In the same table, each account number has several thousand control numbers (apparently the person who designed the DB never heard of Dr. Codd).
Anyway, I want to get the last five created control numbers for each account number. I have a "CreatedDateTime" field that I can use to order the control numbers by creation. I can use the Top and Rank functions to get the last five for an individual account number but I cannot seem to produce a solution with the last five for each account number.
Anyone have any ideas?
Thanks.

I'm building a standard search function for this project im working on and I wanted to know how could I do the following; Basically want I am using the standard "LIKE" function to search keywords but I also want to rank the returns based on how many matches. For example if someone uses the keywords "dog run park fast" and I have a couple of records that have certain amount combinations with these words, how would I return the one that has the most combinations to the least. If one record had "dog, run,park", another has "dog run" and the last would have "fast". How would I being those results in that order.Thanks for any help.

A few weeks ago i posted this and got it to work perfectly. Now im trying to retreive the '3' closest stores rather than just the '1' closest store. How would I go about doing this? I tried using 'TOP 3' in the subquery but you can only retrieve one value.
Here is the origonal post:
"I have a table containing 100 stores, 5000 customers, and the distance between each store and each customer. I am trying to build a query that simply lists each customer and which store is closest and its distance.
Right now it looks like this:
Customer1|store1|33
Customer1|store2|15
Customer1|store3|28
Customer1|store4|35
Customer2|store1|35
Customer2|store2|95
Customer2|store3|28
Customer2|store4|76
I want to get it like this:
Customer1|store2|15
Customer2|store3|28"
Here is the solution:
Code:
SELECT CustomerPost, StorePost, StoreName, Distance
FROM Customer_Store_Distance2 as T
WHERE (Distance =
(SELECT MIN(Distance)
FROM Customer_Store_Distance2
WHERE CustomerPost = T.CustomerPost))

how I could achieve a ranking number, where I have some grouping involved.I want to have the groups in sets of 4, but if I get to a new person the ranking increases, even if I haven't filled the group. For example:
Name Year Sales Ranking
-------------------- ----------- ----------- --------------------
John Smith 2009 1296 1
John Smith 2010 1296 1
John Smith 2011 1296 1
John Smith 2012 1296 1
John Smith 2013 1296 2
[code]....
So, when I get to John's 5 year, the Rank increased. I then only had two more rows before I get to Nina, but the Rank number goes up, as the details are for a different person from the prior user.
Select *, DENSE_RANK() over (Order by Name) + ((RANK() over (Partition by Name Order by Year) - 1) /4) as Ranking
from #Test
Order by Name, Year
Drop Table #TestThis works for John, but Nina then has a Ranking of 2 for her only year, where as she should be 3. Steve also then has a value one too low for all of his ranks.

I have tried to get answers on this before, but haven't had any luck. I am working on trying to finish a report using SSRS in Visual Studio.
The report is a Sales report. I have the report grouped by Location of our Offices and their Customers grouped underneath. The Customers revenue is Summed on the Customers group footer. I have this sorted by Top customer (highest revenue) to lowest customer (lowest revenue). This is fine and great, but now I need to limit the number of Customers (there could be upwards of 100 or more per Office) to the Top 20.
I would like to do this on the report side, but if I need to do it in my SQL query I will.
I would like to get the row number for the Customer group footer. Then I can limit these <=20, but when trying on the report side doing
=rownumber(Customer)
I get an aggregate function error for incorrect Scope.
Any help would definately be appreciated. I have been stuck for about a week now trying to figure this out.

Hi everyone,I am interested in showing a ranking of each result that I get. Basically, the results will be the time of a race along with their name. However, what I want to do is also have a third column that will show their place. I would like my result to be like this:Place Name Time 1 Bob 1:00.002 Bill 1:00.012 Rob 1:00.014 Jill 1:00.025 Jon 1:00.035 Joe 1:00.037 Jane 1:00.04 Records are constantly being added to the table, so the place must be calculated dynamically. Now, I do realize that SQL 2005 has the wonderful RANK() OVER (ORDER BY [time]) AS [Place] feature, but unfortunately SQL 2000 does not have that mechanism. What is the best way to display these results? Should they be included calculated on the SQL side or using the datagridview control? Any help would be greatly appreciated. Thanks,Jason

Hello,
I am having an issue with a SQL query I wrote in SQL 2000. I am almost there but am lacking in one area, hoping a better programmer than me and a fresh set of eyes can pick off my mistake.
The goal is very straight forward, order and rank the following fields:
R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference
The issue lies in my sub query in the AND / OR joins... This query will work if I sort and rank on two fields, but if I try three or more it does not work properly.
Here is my entire query:
SELECT
TOP 100 PERCENT
R1.AutoPoolID,
R1.PoolType,
R1.Week,
R1.Username,
R1.TieBreakerTotal,
R1.Wins,
R1.Losses,
R1.Ties,
R1.TBActual,
R1.TBDifference,
R1.WinPercentage,
R1.Points_Thursday,
R1.Points_Saturday,
R1.Points_Sunday,
R1.Points_Monday,
R1.Points_Total,
(
SELECT COUNT(*)
FROM tblWeeklyStandings_All R2
WHERE R2.AutoPoolID = R1.AutoPoolID AND R2.Week = R1.Week AND
(
R2.PSWins > R1.PSWins OR
R2.PSWins = R1.PSWins AND
R2.PSPoints_Total > R1.PSPoints_Total OR
R2.PSPoints_Total = R1.PSPoints_Total AND R2.PSTBDifference < R1.PSTBDifference
)
) + 1 AS Rank
FROM dbo.tblWeeklyStandings_All R1 INNER JOIN
dbo.qryUsers_SDR ON R1.AutoPoolID = dbo.qryUsers_SDR.AutoPoolID AND R1.PoolID = dbo.qryUsers_SDR.PoolID
WHERE
(R1.PoolType = '2007' OR R1.PoolType = '2008') AND
(dbo.qryUsers_SDR.OrderBy1 = '6') AND
(dbo.qryUsers_SDR.PointSpread = 1)
ORDER BY R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference
At this point I am ready to buy SQL 2005 because I think this gets easier, hoping a 2000 wiz can help me correct my error, or missing "(", or something!
Here are the results:
Rank Username Wins Points TB Difference
1. test 0618084 16 50 0
4. test 0618083 16 50 66
3. test 0618081 15 50 55
4. test 0618082 14 50 55
5. admin 2 0 0
As you can see the ranking is not correct. It should be the following:
Rank Username Wins Points TB Difference
1. test 0618084 16 50 0
2. test 0618083 16 50 66
3. test 0618081 15 50 55
4. test 0618082 14 50 55
5. admin 2 0 0
Sometimes it works sometimes it does not, frustrating!
In different scenerios, I am ranking the following way when ties occur. My code sometimes does this correctly but as you can see above it fails in certain areas, like it forgets R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference....
Rank
1 Tied
1 Tied
3
4
5 Tied
5 Tied
5 Tied
8
etc...
The most frustrating thing is the sort order is correct, it is the rank sub query that fails under certain scenerious...

Hi all,
I've recently tasked my self whereby I wish to rank the info off of a CV and then find matches for this information against a database containing job info, so I'm left with a list of jobs with their relevant perspective possible candidates. I'm thinking of importing the cv as text then manipulating it using Full_text ranking procedures.
Question is do people feel this is the best way of writing what is basically a matching process ?? Is there any 3rd party software out there which does this sort of thing already ??
Any assistance appreciated

Hi all,
Just can't figure this out. I'll try not to give a long-winded explanation (I hope), let's say this is the table, for example:
[Table1]
RowNumber | Value
1 | 4
2 | 6
3 | 3
4 |10
5 | 6
6 | 5
7 | 8
8 | 8
9 | 2
10 | 6
I want to write a query that creates a column whose values are similar to (ROW_NUMBER -1), and resets each time a value is present.
Using the above example, 6 will be the test value. So, I want to know how many rows it takes till 6 is repeated.
Output would be:
RowNumber | Value | Spread
1 | 4 | 1
2 | 6 | 0
3 | 3 | 1
4 |10 | 2
5 | 6 | 0
6 | 5 | 1
7 | 8 | 2
8 | 8 | 3
9 | 2 | 4
10 | 6 | 0
I think PARTITION BY can be used somewhere, with the ORDER BY on the [RowNumber] - but I'm just not sure on which ranking function to use, and how to reset the Ranking on the number 6 (above example).
Any help would be appreciated. This has been a mind-teaser for me, and I give
Thanks,

Hello,
I have a question about writing an SQL query than can run in Access and/or MS SQL Server.
I have a table with the following fields (amongst others):
City
Store
SalesDollars
There are 10 cities, with each city containing 100+ stores, each with a SalesDollars numeric value.
1) How do I write a SELECT statement that will return the top 50 stores from each city (500 in total) ?
2) How do I create a field that is the ranking of all these stores in descending order by SalesDollars (1-500)?
Thank you in advance for your help!

Hello,
I have a group that is custom made on the table's grouping expression, something like
=SWITCH(Fields!Country.Value="Portugal",IIF(Fields!Storetype.Value="Frs","Portugal Frs", "Portugal"),
Fields!Country.Value="Italy","Italy",Fields!Country.Value="Spain","Spain",Fields!Country.Value="United States","United States",
Fields!Country.Value="Internet","Internet",Fields!Country.Value<>"","Other")
The thing is that i order this by my value, and then i use a column that is the rowcount, but sadly i got
11 Portugal
19 United States
30 Spain
How can i do this like
1 Portugal
2 US
3 Spain
Is there something like in C ++1 or something that increments a number depending on the line of the table that is in?
Thank you

Hello-
I was wondering if someone could help me out. What would be the best way for me to go about determining the sale number from the following table:
applicantID calltime result
1 1/5/05 no sale
1 1/15/05 no sale
1 1/25/05 sale
1 1/26/05 no sale
12 1/5/05 no sale
12 1/15/05 no sale
12 1/16/05 no sale
12 1/25/05 sale
12 1/26/05 no sale
the resulting query would provide:
applicantID saleattempt
1 3
12 4
etc. Ultimately, I am trying to figure out how many attempts needed to make a sale.
Thank you...

I have the problem.
I have many Cognos Reports to be converted in Reporting Services.
Out of which there are several Ranking Reports.
Cognos has inbuilt Rank Function while SSRS does not have.
I dont want to do grouping on Database level, rather trying to find a solution in RS.
But unfortunately I couldnt find any solution.
I sorted the group according to requirement, now only thing left is showing the rank number and limiting top 60 rows only.
I tried filters to show TopN, but always gives and error and also tried custom code to show the row number for that group but didn't work.
Anyone has any idea how to overcome this limitation of Reporting Services.
One more interesting is when I try to create a field in dataset having IIF and / within.. RS terminates, all unsaved work gone.
Sometimes I think Microsoft cannot have a product which is 100% perfact and working.

I am using FREETEXTTABLE to enable users to search forum posts. It works extremely well (and fast!) and I am very happy with it.
I also have a top ten list of 'Most viewed' forum posts. Each time a post is accessed, a 'viewcount' value is incremented accordingly. The ten forum posts with the highest viewcount appear in the top ten list (by order of viewcount, of course).
Now... when a user searches on a search term, I would like the top ten list to also be affected by this search.
For example, the user searches on 'foo'. In response they get a list of results containing 'foo'.
However, the top ten list also changes to reflect this. It now shows the ten forum posts with the highest viewcount which also contain the word 'foo'.
This is easy enough to do. The problem arises when we also add proximity searches.
For example, if I search on 'foo bar', FREETEXTTABLE will look for records which have both or either of these words. Records which contain both words will be ranked higher than records which contain either word. And of the records which contain both words, the closer together the two words are, the higher the ranking will be.
But how does this now work with the top ten list? For example, I may have two records:
- Record A has been viewed 10 times. It contains the words 'foo' and 'bar' and they are next to each other.
- Record B has been viewed 10,000 times. But it only contains the word 'foo'.
Now, according to 'viewcount', record B should be ranked higher. But according to FREETEXTTABLE, record A should be ranked higher.
So, I need to combine both these rankings in some way. Regardless of how the 'top ten' records are chosen, they will be ordered by viewcount. But I'm not sure how to get the right top ten records in the first place.
Any thoughts would be much appreciated.

I am trying to build a query in SQL Server 7 that shows my customer ID, customer name, total sales. The query needs to be sorted from highest to Lowest sales. Once the query is sorted I want to put a ranking number beside my total sales field(i.e.1, 2, 3, 4 ....etc.) So far have a query(I did this in Access as a test) that sorts my sales by customer.
Anyone out there know how to get the ranking number beside my sorted list of customers?
Someone has mentioned cursors to me. I have no idea how to use these.
SELECT
Customer.`Customer Name`,
SUM (Customer.`Last Year's Sales`) as total
FROM
`Customer` Customer
GROUP BY
Customer.`Customer Name`
ORDER BY
total DESC
Thanks for the help

Following is my table structure
IDRowCount PagID
1448

3297
4216
5405

[Code] ....
PageId is currently set to 0
I have a user input, @IntNoOfRowsPerPage = 800 Means 800 rows per page. So following is the output I require.
AIDRowCountPageId
1448 1
2267 1
3297 2
4216 2
5405 3
6254 3
[Code] ....
The values of PageID are such that summation of RowCount for PageID is <= @IntNoOfRowsPerPage (i.e, 800)
If NTILE function can be used in such scenarios.

I have a end users that is in need of a some way to rank results in a Report Builder report. I have noticed that neither the RowCount or Ranking function is listed in the avaliable functions or expressions. Does anyone have an idea or solution to perform some type of ranking.
Example:
Name Count Rank
Brad 10 1
Bill 9 2
John 8 3
Seems to be a pretty simple function that was overlooked in Report Builder by MS.

I'm in the process of trying to identify duplicate contacts. I doing this for millions of contacts and have gotten stuck and could use some elegant solutions!
The business rule is this:
Any contact that has the same name, phone and email address are the same contact
Any contact that has the same name, and email address are the same contact
Any contact that has the same name, email address, but different phone are a different contact.
Any contact that has the same name, email address, and a blank phone can be the same contact as one that has the same name, email address, and has an email address
Rank by the DataSource_fk. 1 being the highest
Put another way:
If 3 contacts have the same name, 2 have phone '1112223344' and all three have the email address 'johndoe@gmail.com' they are the same contact and the lowest DataSource_fk should be ranked the highest.
I've used the Row_number over (Partition by) in the past, but am unsure how to deal with the blanks in email and phone.
DROP TABLE [dbo].[TestBusinessContact];

B 5 2
C 6 1
D 4 4
E 2 5
F 1 6Any ideas on how to code a rank function on SS 2000 or Reporting Services?
