I need to find patients(MRN) who are in the 95th percentile for BMI.
create table dbo.TEST
(
MRN varchar(10),
ResultValue varchar(10)
)
insert into dbo.TEST(MRN, BMI) values( '611193','25.63')
insert into dbo.TEST(MRN, BMI) values( '128845','16.93')

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!
How to create Percentile with MDX??
i got this function but i'm not success to follow up.
Percentile ( set, numeric_value_expr, percentile )

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 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
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 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.

I tried all the INFORMATION_SCHEMA on SQL 2000 andI see that the system tables hold pretty much everything I aminterested in: Objects names (columns, functions, stored procedures, ...)stored procedure statements in syscomments table.My questions are:If you script your whole database everything you end up havingin the text sql scripts, are those also located in the system tables?That means i could simply read those system tables to get any informationI would normally look in the sql script files?Can i quickly generate a SQL statement of all the indexes on my database?I read many places that Microsoftsays not to modify anything in those tables and not query them since theirstructure might change in future SQL versions.Is it safe to use and rely the system tables?I basically want to do at least fetching of information i want from thesystem tables rather than the SQL script files.I also want to know if it's pretty safe for me to make changes in thesetables.Can i rename an object name for example an Index name, a Stored Procedurename?Can i add a new column in the syscolumns table for a user table?Thank you

View 1 Replies View RelatedI have a visual studio 2005 app that has to match strings to something in a database.
It works wonderfully until a string shows up with an & in it (so "this & that")
The app wont find anything even though it should, the same query that is made in VS works just fine in enterprise manager
I tried a replace on the & with the chr(), hex, and html reference for & and none of those work.
We tried using different methods in VS to do the sql statement and commands.
The statement surrounds the string with single quotes.
If we take the & out, everything works fine.
Turned off request valadation just in case.

Hi, All
I have a problem with one table.
This table is corrupted so I drop the table and recreate the table..(Of course I export data) After that I try to put the primary key to new table but it won't allow me to do it. Error message says " There are duplicated key existed" Therefore I open up the EM and take a look at that table. There is key in that table but not Primary key..(also from the query analyzer using sp_help)
My question to U is how can I find this duplicated key and delete that info? I think somewhere in the system table contains this info but I don't know where:-(((
Thanks in advance..
