Hi All,
I have around 1000 employee records containing employee number and their salary. How do i calculate percentile on these records?
For example
How to calculate 25th Percentile on Salary of these 1000 records?
Hope I am clear with my question.
Thanks in advance.

I am using sql server 2008 to calculate the percentile value for each column.
--Script
CREATE TABLE #Table (Score Varchar(4),Percentile int)
INSERT INTO #Table (Score)
VALUES
('80'),('55'),('125'),('99'),('75'),('130'),('37'),('73'),('151')
select * from #Table
I would like the result to be shown in 25,50,75,100 percentile values . Here is the example
Score | percentile
80 | 75
37 | 25
151 | 100
75 | 50
Any good way to add a percentile calculation to a table in sql server 2008 r2?
I've got 4 fields and I'd like to add a 5th labeling the records according to the percentile they fall in for one of the fields.
I have created calcalated measures in a SQL Server 2012 SSAS multi dimensional model by creating empty measures in the cube and use scope statements to fill the calculation.
(so I can use measure security on calculations
as explained here  )
SCOPE [Measures].[C];
THIS = IIF([B]=0,0,[Measures].[A]/[Measures].[B]);

How to create Percentile with MDX??
i got this function but i'm not success to follow up.
Percentile ( set, numeric_value_expr, percentile )
(set -> The set from which to get a tuple value.
numeric_value_expr -> A numeric value or an expression that returns a numeric value.
percentile -> A percentile. Must be between 0 and 100. )
Thank you
Hi, l would like to calculate 80% and 95% percentile of a column from my table in SQL server 2005. Does SQL server 2005 provides such built-in function, if not, how should l do? Any suggestion? (Suggest to MS : Please include percentile as a built-in function on the next services pack). Thanks and happy labor day!

Hello All,
Does anyone know how to do an expression that calculate percentrank and percentiles? I have a table with a list of transactions and their response time. I need to find the 75th, 90th, 95th, and 98th percentile as well as the percentrank of <=5 seconds, 10 seconds, 30 seconds and 60 seconds.
Any help is appreciated!

I'm trying to create a calculated field that gives me the avg 75 percentile.
Right now I get this value by doing the following:
Create data set:
Select top 75 percent <field>
from <table>
Then I create the following calculated field
Avg(Fields!<field>.value,"<data_set_name>")
But I wanted to be able to create a calculated field that gives me the avg 75 percentile without creating a separate data set to get the top 75 percent Value.
Is it possible?
Thanks!
I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores
(
id int primary key identity(1,1),
student_id int not null,
score int not null
)
with some sample data:
insert into StudentScores (student_id, score)
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 88 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int
set @studentid = 2
select top 1 @studentid as student_id, a.score as [90th percentile score]
from
(
select top 90 percent score from StudentScores
where student_id = @studentid order by score asc
) as a
order by a.score desc
But I want this for all students, and not use a cursor.
Any ideas?
Thanks!
I am writing some scripts to calculate mean (avg) stdevs count and percentile_cont for some data..I am partitioning over multiple columns e.g. partition by year,month, day order by value..I performing unnecessary overhead as I throw away all but the last (or max) value in each window. (I use cte then select max from cte).That is I only care about the avg of the window in its entirety not specific subwindows.

Hi,
My predicament is - where do I do these calculations - in my vb.net code or in an SQL stored procedure?
My manager has handed me a task of converting an excel file she uses in to a web aplication.
While it has been easy to devise what should be the screens and how to capture data, I am struggling over how to code the calculations.
The calculations in excel are pretty simple. These are just sequential calculations (about a 150 calculation for average 500 rows). Mathametical operations include sum, average, max min - regular excel stuff. Some calculations involve vlookup (equvalent to calculation based on value derived from a reference table).
So I am stil wondering - where do I do these calculations - in my vb.net code or in an SQL stored procedure?
Since these calculations are required a produce a result in an online environment, what will be faster?
I tried to do a proof of concept by creating a sample calculation in a .NET class and an in a stored procedure. The choice is still not clear. SQL code execution time was not bad. But SQL code tended to be very messy.VB.net code seemed to be a little slow. But seemed a more organised to look at.
Any views that you can offer will be very helpful.
Thanks in advance.

My aim is to do something like what I have explained below and I was planning on building this logic at the Database level only rather than on the frontend code.
There are certain allocations(transactions) that happen on a periodic basis and I am storing these transactions in the PurchaseTranMaster and PurchaseTranDetail table. These transactions are categorized as 'Main' type and the amount could be allocated for one or many categories in a single transaction. Below is how it will be saved in the 2 table
PurchaseTranMaster
TranID TranDate TranType
1 14-March-2008 Main
2 17-March-2008 Main
3 1 9-March-2008 Main
PurchaseTranDetail
TranID Amount Category Debit_TranId
1 1000 A
1 1000 B
2 2000 B
3 300 A
3 400 C
Now what happens is users of my application can make purchases under all these categories only until the Balance under these categories is > than purchase amount. The Balance is calculated as sum of all transactions. It means that w.r.t the above data the balances for each category is(this is not stored in the database)
A 1300
B 3000
C 400
So lets say a user does make a purchase(Trantype is 'SUB') of 300 under A and 400 under B in a single transaction. The data would then be stored in the tables as
PurchaseTranMaster
TranID TranDate TranType
1 14-March-2008 Main
2 17-March-2008 Main
3 19-March-2008 Main
4 20-March-2008 SUB
PurchaseTranDetail
TranID Amount Category Debit_TranId
1 1000 A
1 1000 B
2 2000 B
3 300 A
3 400 C
4 300 A 1
4 400 B 1
In the PurchaseTranDetail the Debit_TranId value means that the amount has been marked against the TranID 1. This TranId is not handpicked by the user and the system should allocate it accordingly based on the amount available for a particualar category for a Main Transaction. It means that before TranId 4 was saved in the database then the system would first check whether the Total available balance for A >=300 and B>=400 (in our example above it is 1300 and 3000 resp)
Then if the Balance is > than the puchase amount then the allocation would be done by the system and this would be done against the TranID whose TranDate was the earliest, so thats why the Debit_TranId column has 1 as TranId 1 was the earliest.so logically now the balance for the categories would be (this is not saved in the database)
A 1000
B 2600
C 400
So next time again when a user would make a purchase(transaction) under A for 800 and under B for 1000 then if the balance is greater than the purchase amount(which in this case it is) the allocation would happen according to the earliest TranId and this time amount would be partly marked against TranId 1 , TranID 2 and TranID 3. The data would look like this
PurchaseTranMaster
TranID TranDate TranType
1 14-March-2008 Main
2 17-March-2008 Main
3 19-March-2008 Main
4 20-March-2008 SUB
5 21-March-2008 SUB
TranID Amount Category Debit_TranId
1 1000 A
1 1000 B
2 2000 B
3 300 A
3 400 C
4 300 A 1
4 400 B 1
5 700 A 1
5 100 A 3
5 600 B 1
5 400 B 2
I need to do the above taking into consideration that there could be multiple users making purchases(concurrency).
Also I was building my logic on doing the above whether to use cursors or loops. I just need to know how do I write my stored procedure and what would be the most efficeint way of doing the above.
The design for creating the above sample tables is below
/*CREATE TABLE PurchaseTranMaster
(
TranID int IDENTITY(1,1) PRIMARY KEY CLUSTERED,
TranDate Datetime,
TranType varchar(30)
)
CREATE TABLE PurchaseTranDetail
(
TranID int,
Amount int,
Category Varchar(20),
Debit_TranId int
)
insert into PurchaseTranMaster values(convert(datetime,' 14-March-2008',103),'Main')
insert into PurchaseTranMaster values(convert(datetime,' 17-March-2008',103),'Main')
insert into PurchaseTranMaster values(convert(datetime,' 19-March-2008',103),'Main')
insert into PurchaseTranMaster values(convert(datetime,' 20-March-2008',103),'SUB')
insert into PurchaseTranMaster values(convert(datetime,' 21-March-2008',103),'SUB')
insert into PurchaseTranDetail values(1,1000,'A',0)
insert into PurchaseTranDetail values(1,1000,'B',0)
insert into PurchaseTranDetail values(2,2000,'B',0)
insert into PurchaseTranDetail values(3,300,'A',0)
insert into PurchaseTranDetail values(3,400,'C',0)
insert into PurchaseTranDetail values(4,300,'A',1)
insert into PurchaseTranDetail values(4,400,'B',1)
insert into PurchaseTranDetail values(5,700,'A',1)
insert into PurchaseTranDetail values(5,100,'A',3)
insert into PurchaseTranDetail values(5,600,'B',1)
insert into PurchaseTranDetail values(5,400,'B',2)*/
I´m working on SSRS 2005 trying to calculate YTD for the total sale. This is what I got so far:
Code Snippet
WITH MEMBER [Measures].[YTD Amount] AS
'SUM(PeriodsToDate([DATE].[Year]),[Amount])'
SELECT
{[Measures].[Amount],[Measures].[YTD Amount]} ON COLUMNS,
[DATE].[Month].Members ON ROWS
FROM [SKY]
My Date hierarcy is:
Year
Month
When running this query all I get is very small number for Amount column, almost zero for all months and the YTD Amount Column is only showing (null).

I need to create a user defined function to calculation the difference between today and a future date. The result needs to be in days, hours, and minutes formatted as per the following example: 1d / 4h / 30m. I have a moderate level of SQL exprience. however, I would appreciate some expert advice as the best way to approach this.

HI,
getdate() gives me today's date. I have a sql query which returns me a date. I want to see if the difference between today's date and the date returned by sql query is 12 months(1 year) or less. If yes I want to print it.
(If the difference is more than 12 months or 1 year i don't want to consider that record.)
Example:
how to do calculate:
10/05/2004-10/3/2003
how do i calculate something like this if I have the table with names and count?
Name Count Percent
Name1 27 4.69%
Name2 2 0.35%

Totals 576 100.00%
:eek:
I am performing a calculation in both SQL and MSACCESS. ACCESS is correct and SQL is not. It is off by -.05 Here is the calculation:
Sum((ch.FaceAmount)-(((ch.FaceAmount*Ex.CAN_Exchange_Rate+0.005)*100)/100)) AS TransAmount,
Both FaceAmount and CAN_Exchange_Rate are defined as money in a SQL table. The ACCESS front-end attaches this table, so it uses the same columns in the calculation.
Now, I know SQL looks at money with 4 decimal places. The attached SQL tables in ACCESS looks at these columns as currency which I believe is 2 decimal places. I think this is where the descrepency is. But it still doesn't explain why SQL is calculating the incorrect total.
Does anyone have any ideas?
