Percentage Help
May 26, 2006
I need to write a page that figures out the percentage of students passing an assessment item where students are from a particular school, grade, gender, and are not medically exempt.
I did a Count Statement on all test taker, and another Count Statement for the number passing the item who were not exempt. Both of the statements are shown through seperate datalist controls. I then want to get the percentage by dividing the number passed by the number taken and mulitplying that by 100.
Is there a better technique or can I do this in a sql statement somehow?

Hi i create a temp table that count how many A,B,C and D there where in a table.
I need calculate the percentage.It could be easy put the problem is that i cannot devide by the same number.
Here my temp table DECLARE @Temp table
(
strLastName varchar(50),
strFirstName varchar(50),
strReponse char(10),
strNomObjet nvarchar(200),
strDescripteurOrdre char(10),
strNomDescripteur nvarchar(200),
strObjetOrdre char(10)
)
I want to check how many A there is.
SELECT strNomObjet,strNomDescripteur,count(*) FROM @Temp
WHERE strReponse = 'A'
GROUP BY strNomObjet,strNomDescripteur
This will give me somthing like this
For the first one there 25 A
Second 27 A

After that i use
SELECT count(*) FROM @Temp

That will give me how many person have been tested.
It will give me this
36
36
35
36
35
36
36
35
35
So i need to take the first 25
25 / 36 * 100 = 69.4%
27 / 36 * 100 = 75%
26 / 35 * 100 = 74.2%
I hope you understand what i mean!
Any idea?
Tks in advance

Hello!I have a need to create a function that will return a sublist ofelements from a table based on an associated column value and itsranking within the table (based on a percentage range).To expand with a simple example (only 4 elements):Element | Value---------------A102 | 5A506 | 10A322 | 15A342 | 20I would like to be able to return the range of elements that lie in the50-75% value range (e.g. third quartile range). Therefore with onlythese four elements I would want to return the element code 'A322'.I have attempted to achieve this by using SELECT TOP n PERCENT. I canbring back the required range by combining two select percentstatements.SELECT Element from ELEMENT_TABLEWHERE Element IN(SELECT TOP 75 PERCENT Element FROM ELEMENT_TABLE ORDER BY Value)AND Element NOT IN(SELECT TOP 50 PERCENT Element FROM ELEMENT_TABLE ORDER BY Value)The problem is that I cannot seem to pass a variable to this percentageso if I want another percentage range set, I ave to define anotherfunction.My question therefore is does anyone know either(1) a way I can pass a variable (n) to these SELECT n PERCENTstatementsOR(2) an alternative way of doing this?Many thanks!Andrew

Lets say I have a table called ProductProductId Name Price Category1 Table 20.00 Furniture2 Chair3 Lamp Misc What is the SQL command that would give me as a percentage the completeness of a row, either complete or empty?For e.g. SELECT ... FROM Product WHERE ProductId = 2 ; should give a result of 50% as half the Columns in that row are empty.e.g. SELECT ... FROM Product WHERE ProductId = 3 ; should give a result of 25% as 1/4 of the Columns in that row are empty.I tried used something like SELECT COUNT(COLUMN_NAME) AS Expr1FROM INFORMATION_SCHEMA.COLUMNSWHERE (TABLE_NAME = 'Product')but dont know how to go forward.

Ok guys, here is my query
GridSqlDataSource1.SelectCommand = "SELECT *, (([WinSum])/(([WinSum]) + ([LossSum]))) AS WinPercent FROM [ResultsView] WHERE ([CDIV] = @CDIV) ORDER BY [CTEAM]"
I need it to give me a 3 decimal percentage for WinPercent, but right now it is giving me 0 because as an example:
6 / 7 = 0 instead of 0.857
Any ideas?

Hi Guys,
I am in need some uinderstanding of how to return the percentage of calls that were closed, between 1, 2 ,3, 4 and 5 days (possibly extendable to catch all those that were holding on to jobs to make it look like the were busy) as well as including all open jobs.
Because of my newbie status I am stumped at how to even start a query of this magnitude, and no this is not a school assignment :-) just some one who is very new to T-SQL and wanting to learn how to extract data from an MS SQL database server, as I find it fascinating, also my bosses find it fascinating the type of data I am returning for them so far.
So enough waffling.
This query will be run through VBA, any variable(s) will be supplied by VBA.
DB name = Envisage
Table name = HD_Call
Columns = DateRaised (datetime, null), DateCompleted (datetime, null)
Help in understanding how to construct this query will be grately appreciated.

Hi,
easy question for advanced users:
I have a dimension called "Movement rate". The members are "1" to "6".
There is a measure called "No. of Products".
What i easily like to do is showing the percentages "No. of Product" for each "Movement rate" of the amount of "No. of Products" without using the frontend-tool.
Thx in advance for any help.

I am relatively new to SQL i.e. I know the basics!
What I am trying to do is: I have a database of customer spend and I am trying to segment them into certain %ages of the search results. So, for example, find all of the customers that are in the top 10% of spenders (I also want to only select customers with a spend of greater than x!). I am trying to do this using a Case When but feel that I may be out of my depth.
Please help if you can!!

My site has members. Each member has a certain goal, an amount that they are hoping to raise. Here's my tables:
---------------------
Members
---------------------
ID | Goal
---------------------
---------------------
Donors
---------------------
Amount | MemberID
---------------------
I'm trying to get the percentage of money raised compared to their goal. Basically 100*(SUM(Amount)/Goal). Here's my stored procedure:
CREATE PROCEDURE sproc_GetGoalPercentage
(
@memberid int
)
AS
SELECT(SUM(D.Amount)/M.Goal)*100
FROMMembers AS M INNER JOIN Donors AS D
ON M.ID = D.MemberID
WHEREM.ID = @memberid
GROUP BY M.Goal
RETURN
All it does is return 0.

I am trying to figure out the syntax for a query that will essentiallygive me the Percentage each of my areas contributes to the Whole. Iknow this can be achieved by multiple queries but I would like to keepit intact as one single query if possible.For Example I have the following data set--AREA MOUNE 1234SO 4312WE 12312MW 97123NE 1123SO 31WE 312MW 971The results I would like to see would look likeAREA MOU PERCENTMW 98094 .83536NE 2357 .02007WE 12624 .10751SO 4352 .03706The query I came up with is--SELECT DISTINCT Area, SUM(MOU) AS AREA_TOTAL, sum(MOU) /(SELECT SUM(MOU) AS TOTAL_MOUFROM [2004_NOVEMBER_COST])as[PERCENT]FROM [2004_NOVEMBER_COST]GROUP BY AreaAll seems to calculate with the exception of the Percent where all thepercentages are 0's.I think I need to take the first line AREA_TOTAL and now divide by theSUM(MOU) like this--SELECT DISTINCT Area, SUM(MOU) AS AREA_TOTAL, AREA_TOTAL /(SELECT SUM(MOU) AS TOTAL_MOUbut I get Invalid Column.I essence I think it is a simple query but I am hitting a wall. Anyadvice would help.Thanks,Ben

Hello,
I have a matrix that looks as follows:
Name Jan Feb Total
John 5 6 11
Mary 3 4 7
Total 8 10 18
I want to add a percent column to the RIGHT of the total, and also on the bottom row. I can't find any clear examples of how to do this. If I had a new column, it adds additional headers beneath my top row. Or, my columns appear to the LEFT of the data, not the right. Can some please post some simple instructions that will make my simple matrix look like this:
Name Jan Feb Total %
John 5 6 11 60%
Mary 3 4 7 40%
Total 8 10 18 100%
% 40% 60% 100% 100%
I am so stuck on this I can pull my hair out.
Thanks!
Michael
p.s. I really hope the next version of SSRS has a simple "Sub-total %" option that you can enable just like the sub-total column.

7 thru 8 mos
8 thru 9 mos
9 thru 10 mos
10 thru 11 mos
11 thru 12 mos
Total
I'm wondering how to calculate the Balances as a %. Because I dont know how to calculate the Total for 12 months.
Basically Balances as a % = (Balance for 0 thru 1 mos / Balance for whole 12 mons)%
But the problem is calculating the total balance for 12 mons.
Can any one help me please?

Hello,
I am working on generating a Pie Chart in Reporting Services. I want to display percentage (%) in the pie chart slices, rather than having the actual values, since it does not fit properly into charts. A percentage would be better as a report.
Hope the question is clear. I would be grateful to anyone who answers this question.
thanks a lot.

I'm working with SQL RS 2000 and am putting together some pie charts. In my query, I am counting the total number of records grouped by a case statement so I get the total of one specific type and then the total of all other. What I am wanting to do is in addition to having the actual record count, I would like to also show the percentage of the whole. In the past, what I have done is written a separate query that does not do any grouping and then in my report, divide my individual total by my grand total and get my percentage that way.
I was just wondering if there is any way to get the percentage without having to write the additional query?

I am trying to get the a percentage from two columns, but I can not figure out how to do it. An example of my data is:
NAME MAX ACT
Red 1000 78
Blue 1000 247
Yellow 1000 472
My thoughts was to do something like:
SELECT NAME, MAX, ACT, ((ACT / MAX)*100) as PERCENTAGE
FROM TableName
When I do this the PERCENTAGE column just has 0s. Could someone tell me can this be done....and what am I missing.
FYI: Columns MAX and ACT are Int (4)
Thanks!!

How do I write a query to give me the total records in databaseA.tableA divided by the total records in databaseB.tableA
This is what I have so far:DECLARE @today as datetime
DECLARE @past as datetime
/* set the dates */
set @today = getdate()
set @past = getdate() - 3 /* Go back 3 days */
/* create temp table for holding total cases*/
CREATE TABLE #CaseTotalCount
(
TotalCount int
)
/**/
CREATE TABLE #FlashCycleCount
(
FlashCount int
)
/**/
INSERT INTO #CaseTotalCount (TotalCount)
SELECT COUNT (DataBaseA.dbo.tblProcedureData.CaseID) as TotalCount
FROM DataBaseA.dbo.tblProcedureData
WHERE DataBaseA.dbo.tblProcedureData.Date < @today AND DataBaseA.dbo.tblProcedureData.Date > @past
/**/
INSERT INTO #FlashCycleCount (FlashCount)
SELECT COUNT (DataBaseB.dbo.tblFlashLog.FlashLogID) AS FlashCount
FROM DataBaseB.dbo.tblFlashLog
WHERE DataBaseB.dbo.tblFlashLog.LoadDate < @today AND DataBaseB.dbo.tblFlashLog.LoadDate > @past
/*function call*/
SELECT dbo.percentage(#FlashCycleCount.FlashCount, #PeriOpTotalCount.TotalCount)
FROM #FlashCycleCount
JOIN #PeriopTotalCount
ON #PeriOpTotalCount.TotalCount != 0 This works but when I try to bind this to a formview a get nothing. any ides?

Hi,
I would like to generate following table with reporting service matrix.
But if I use the expression : percentage coulmn=sum(field!qty.value) / sum(field!qty.value, "region_group")
It will become a percentage of a row total, instead of a group total (store group). Please see the second table.
Any ideas?
Thank you!
