Rank Function
Jul 30, 2007Hi ,
I have a report created and within the report is columns that perform additions on the fields from the database.
I want to create a rank column to show the rank of the row compare with the rest.
Col1 Col2 Total Ranks
1 2 3 3
2 3 5 1
2 2 4 2
On the above Col 1 and 2 would come form my database, Total is calculated by the report. How can I get ranking on this total? I cannot sort by the total as the report should only showing rankings but not be ordered by the rank.
I am using SQL Server 2005 Reporting Services...anny help is much appreciated.
Thanks
SQL Server 2012 :: Incorporate RANK Or NTILE With LEAD Function?
Jan 9, 2014We have accounts that pay for a particular "premium" service. It's entirely possible an account paid for this service for three consecutive months in 2013, then stopped paying, then started paying again. Why I'm trying to establish is, for the FIRST period of time the accout paid for this service, for how many consecutive months did they pay? Here is my test data:
if object_id('tempdb..#SampleData') is not null
drop table #SampleData
go
if object_id('tempdb..#DateAnalysis') is not null
drop table #DateAnalysis
go
-- Create temp tables for sample data
create table #SampleData
(AccountID int,
RandomDate datetime)
create table #DateAnalysis
(RowID int identity(1,1),
AccountID int,
RandomDate datetime,
NextDate datetime,
LeadInMonths int)
-- Insert some sample data
insert into #SampleData values
(1, '1/1/13'), (1, '2/1/13'), (1, '3/1/13'), (1, '6/1/13'), (1, '10/1/13'), (1, '11/1/13'), (1, '12/1/13'),
(2, '1/1/13'), (2, '4/1/13'), (2, '5/1/13'), (2, '6/1/13'),
(3, '2/1/13'), (3, '3/1/13'), (3, '4/1/13'), (3, '9/1/13'), (3, '10/1/13'), (3, '11/1/13')
-- Use lead function to determine how many months are between
-- consecutive dates per account
; with DateInterval as
(select AccountID, RandomDate,
NextDate = lead (RandomDate, 1, NULL) over (partition by AccountID order by RandomDate)
from #SampleData)
insert into #DateAnalysis
select AccountID, RandomDate, NextDate,
datediff(mm, RandomDate, NextDate) as 'Lead'
from DateInterval
where NextDate is not null -- Last row will contain NULL for NextDate. Don't include these rows.
-- Show the results
select *,
'NTile' = NTILE(3) over (partition by AccountID order by RandomDate),
'RowNum' = row_number() over (partition by AccountID order by RandomDate)
from #DateAnalysis
Results (this is not getting me what I'm looking for):
RowIDAccountIDRandomDateNextDateLeadInMonthsNTileRowNum
11 2013-01-012013-02-01111
21 2013-02-012013-03-01112
31 2013-03-012013-06-01323
41 2013-06-012013-10-01424
51 2013-10-012013-11-01135
61 2013-11-012013-12-01136
72 2013-01-012013-04-01311
82 2013-04-012013-05-01122
[code]....
This is what I'm trying to achieve:
RowIDAccountIDRandomDateNextDateLeadInMonthsRankForThisLeadInMonths
11 2013-01-012013-02-0111
21 2013-02-012013-03-0111
31 2013-03-012013-06-0132
41 2013-06-012013-10-0143
51 2013-10-012013-11-0114
61 2013-11-012013-12-0114
[code]....
The problem comes with accounts like AccountID = 1. They paid consecutively to start, then skipped, then started paying consecutively again. When using window functions, I'm running into trouble attempting to partition by AccountID and LeadInMonths. It's putting all the LeadInMonths = 1 together and that will give me skewed results if I want to know the earliest and latest date within the FIRST consecutive range of dates where the account paid. I've tried NTILE but it expects an integer and there's no telling how many "tiles" would be in AccountID partition.
I've looked at the OVER clause and the new "ROWS BETWEEN" syntax and still cannot get the desired results.

Please let me know the equivalent of RANK() over ( order by...)

I thought this was supported in SQL server 2000.
Please let me know if there exists a user defined function.

May 22, 2006I've written a bunch of code using contains for fts. Then as I was trying to run the sorting, I realized that I have to use containstable in order to sort by rank. Is that correct? When I was using contains, I just used it as a where clause so I would have something like...
WHERE ((PostedUntil >= '5/22/2006') AND (SiteId=199)) AND (CONTAINS (PositionTitle, '"sales"') OR CONTAINS (Description, '"sales"'))
From the examples I've seen, in order to use containstable, I have to join a new dynamic table to the freetext enabled table and it only uses 1 containstable phrase for the new table. In my case, I may have multiple containstable phrases, so would they all fall in a () set like..
FROM Categories AS FT_TBL INNER JOIN
(CONTAINSTABLE (table, col1, searchphrase) OR (CONTAINSTABLE(table, col2, searchphrase2) OR CONTAINSTABLE (table, col3, searchphrase3)) AS KEY_TBL
... or would each containstable have to be a new join? I don't want to spend anymore time going back and rewriting code just to test it since it's about a days worth of recoding. Thanks.

Rank Equation
Jun 7, 2006Hi all,
until recently ive been using a rank equation to calculate rank,
essentially doing a select statement and selecting this as the rank field, where query 2 is the same as query 1:
((select count(*) from (query1) where (query1).value < (query2).value) +1)) as Rank
problem is that this is now running like a dog (takes 10 secs) and i'd like to try and do this another way- 2005 has a rank function, how can i do this in 2000?
here is the full statement :
SELECT StudentId, GCSE_Score, LTRIM(STR
((SELECT COUNT(*)
FROM dbo.[Score2004-05]
WHERE GCSE_score < s.GCSE_Score) + 1)) AS GCSE_Rank, SetId
FROM dbo.[Score2004-05] S
WHERE (SetId = '2004/2005')

Rank In FREETEXTABLE
Apr 8, 2008I need help in understanding how the rank is calculated in FREETEXTABLE. I have a following query
select ft_tbl.saon
,ft_tbl.paon
,ft_tbl.street
,ft_tbl.postcode
,key_tbl.rank
from temp as ft_tbl
INNER JOIN freetextTABLE(temp, (saon, paon, street), '80 ridge avenue', 15) as key_tbl
ON FT_tbl.ID = key_tbl.[key]
First, the resulting rows does have one record which has an address 80 ridge avenue but it appears at 15th place. Ideally it should appear on 1st. All the ranks of the results are same.
Second, the results are also showing two rows which does not contain the specified search string at all. They not only appears above in the resulting table but also have the same rank as the result in question (80 ridge avenue). For example result shows €œLong Ridges, Flat 21, Fortis Green€? at fifth place which is no way near the search string. And actual record shows up at 15th Place
Is there any way we can influence the rank to show exact match first. Just to clarify I have removed the digits from noise file as we need to search house numbers. Digits appears in noise file as default.

Rank Beginner Does Not Know How To Get Started
Sep 14, 2007Hi - Can someone point me to a single document that tells me how to get started from nothing with SQL Server 2005 Express? I keep getting pointed to lists of many documents, none of which does what I specifically need. They all seem to have many general instructions, but I just want to get started with some simple database that I load with a bit of data and then perform some queries.
I have ordered a book from Amazon but don't have much hope that it will do what I need.

Transact SQL :: RANK - Using To Take Only Changes For One Column
Nov 8, 2015I have a table that has the definition from the picture. Let's suppose I will sort the list based on last column (DATA.ORA - DESC). That means the last row inserted is the first one in the sorted list.
What I would like to do is to get only the records when the value of a specific column is different from the row below.
For instance I would like to get the rows where the column WHITE has different values. When the status for column WHITE changes from 0 to 1 or from 1 to 2 etc., then I need that row no matter if next 5 rows has the same status (1).
In the picture you see what the result of query should be:
Result: only the lines where the value of column WHITE is different than the row below.

Need To Count And Rank NVARCHAR Column
Apr 2, 2008Assuming that I have a table similar to this simplified version:
CREATE TABLE [SomeTable] ([Field1] NVARCHAR(50));
How could I count and rank the instances of specific values in the "field1" column? For example, let's say that I want to show the frequency of the column values like so:
field1 count
some value 24
another word 20
a value 5
(and so on...)
How can I do this?

Data Load Based On Rank
Aug 9, 2007I'm fairly new to SQL and I have been asked to load multiple tables with duplicate and inconsistent data into a single table. Each source (table) has been assigned a rank in terms of the quality and reliability. After some thought, I have come up with this solution to get all of the data loaded based on rank.
Does anyone know of a better way to do this?
Value is a unique key.
SELECT *
FROM table_1
union
SELECT *
FROM table_2
where (value + '_' + yr) in
( select value + '_' + yr
from table_2
except
select value + '_' + yr
from table_1)
union
SELECT *
FROM table_3
where (value + '_' + yr) in
( select value + '_' + yr
from table_3
except
select value + '_' + yr
from table_2
except
select value + '_' + yr
from table_1)
Create A Rank Column In A View
Jan 14, 2008Hi all!
I'm trying to script a view that does a simple query to some tables.
The catch is 2 of the columns are created on run time.
The first column is filled with a calculation with values of other columns. The 2nd column I would like to fill with the ranking of this calculated column
Example: (imagine caculatedcol is Sum(Col1+Col2+Col3)
Col1 Col2 Col3 CalculatedCol Ranking
10 10 10 30 1
9 9 9 27 2
8 8 8 24 3
7 7 7 21 4
How can I get the Ranking column filled based on the calculated column?
I'm desperate.
Thanks for any help.

How To Rank An Union Of Two Result Sets?
Mar 1, 2007I am new to SQL Server Integration Services. I need to help here.
If there is only one result set, I could get rank info by putting DENSE_RANK expression inside of my select. My case is that I have two data source. After union of them, I need rank the result set and save result set plus rank info into the destination. I tried to use Derived Column component by using expression DENSE_RANK() over ( order by columnName ). But it does not like it.
Does anyone know how to achieve this?
Thanks!
Combining FREETEXTTABLE Rank With Another Ranking
Jul 26, 2007I 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.
