Percentage In A Query
Oct 28, 2005
Hi,
I am creating a database to help me monitor the students in my class. I have a query that takes a student mark from one table and compares it with the maximum mark available for the assessment/homework. In a calculated field called Percent I divide the mark by the maximum mark and then multiply by 100. This gives me the percent. I then have another calculated field which awards a grade from A to C and if they don't achieve a C they are awarded a Fail. The IIf statement looks like this:
Grade: IIf([percent]>="70","A",IIf([percent]>="60","B",IIf([percent]>="50","C","Fail")))
Here is the bit I don't understand. If a student gets 99 % they are awarded an A (cut offs are: 70% and above for an A, 60% to 69 % for a B and 50% to 59% for a C. 49% and below gets a fail). If they get 65% they get a B... all appears fine. But, if they should happen to get 100% the query says "Fail". Can someone shed any light?
Regards
Kevin

Below is the code I am using in a query that produces results that look like:
Fault Category------------No Fault Totals
No Faults-----------------------77
Total Work Units---------------521
I would like to also show in the query the percentage of No Faults. In this instance I would need to divide
the 77 no faults by the 521 total work units. Is there a way to do this and show the answer in the query.
I do not want this in a report, just the query.
SELECT FaultCategory, COUNT(*) As [No Fault Totals]
FROM WorkUnitsFaultsMainTBL
WHERE BuildID IN ("E010","C809","F001","C810","F187","A910","M173","M174") AND
FaultCategory IN ('No Faults') AND
[TodaysDate] BETWEEN [Forms]![Queries_ReportsFRM]![StartDateTxt]
AND
[Forms]![Queries_ReportsFRM]![EndDateTxt]
GROUP BY FaultCategory
UNION ALL SELECT 'Total Work Units' As FaultCategory, COUNT([WorkUnit]) As [WU Totals]
FROM (Select Distinct [WorkUnit]
FROM WorkUnitsFaultsMainTBL
WHERE BuildID IN ("E010","C809","F001","C810","F187","A910","M173","M174") AND
[TodaysDate] BETWEEN [Forms]![Queries_ReportsFRM]![StartDateTxt]
AND
[Forms]![Queries_ReportsFRM]![EndDateTxt]) As vTbl;

Hi, All:
I have been struggling for this question for a long time.
I have a total query coming from two tables. This query has following field:
productline
device
component
The table has more field. One of them is status for component field.
My application is that there are many productline. Under each productline, there are many devices. Under each device, there are many components. Each component has one of 4 statuses. The status is text value, 'Yes', 'No', 'UR', and blank.
In the form, I need to use continuous form to display each device with totalcomponent (I use Count of component), percentage of status1 based on totalcomponent, percentage of status2, etc.
My question is:
I tried to use Count(IIF([status] = 'Yes', 1, 0)) to get percentage. But [status] = 'Yes' seems not right because I got a count of all statuses, the same result of CountOfComponent
Really need help
Thank you much

How to calculate the percentage of kilometers per order compared to the total number of kilometers per carrier.
In the attached screenshot send queries where I need formula.
Mileage on the orders of the field called "Korkma" . The formula should look like: # [Korkm] / [total kilometers per carrier] #.
I do not know how to get the total mileage driven by the carrier (the carrier is in the query in the Field Name Plate) for the month.
For example:
date 1.1.2013.,Plate:Pribus Korkm= 37
date 2.1.2013.,Plate: Pribus,Korkm=56
date 10.1.2013.,Plate: Pribus, Korkm= 70
Formula: [37]/[163] = 0,23
[56]/[163]= 0,34
[70]/[163]= 0,43

I am trying to set up a calculation between two values to show the percentage difference. In Excel, for example, I would have two values, £905,175 and £891,563, and I would enter =A1-G2)/ABS(A1), which would then return a plus or minus percentage value. how to do this in a query using Access 2010?

I have a database which tracks the performance of my team and how long it took them to send something out to the customer. We have a target of 5 minutes.
So I quite a few queries to drill down this information. I have a summary query that takes that information and tells me the total amount of things sent, the amount of things sent in time and the amount of things sent late.
My team have to get at least 95% out on time. So how would I go about adding this bit into the query. The calculation is:
The amount sent on time / the total amount * 100
But is there anyway to add this into a 4th column displayed next to these figures?
Looking around a few people have talked about SQL but I no nothing about this and it seems quite daunting, is there a way to do this as a calculated field?

I have created a cross tab query that contains a row heading for Entity and Total Cases. I would like to have a percentage of the Case Total for Each Category as well as the count for each category. It works fine for just the counts and here is the sql behind it:
TRANSFORM Count(CASEDATA.CASESTATUS) AS CountOfCASESTATUS
SELECT IUIDCODES.CODEDESCRIPTION, Count(CASEDATA.CASETYPECODE) AS CountOfCASETYPECODE
FROM (CASEDATA INNER JOIN CASESTATUSCODES ON CASEDATA.CASESTATUS = CASESTATUSCODES.CODEID) INNER JOIN IUIDCODES ON CASEDATA.IUID = IUIDCODES.CODEID
WHERE (((CASEDATA.CASETYPECODE)=63) AND ((CASEDATA.FYSTATUS)=6 Or (CASEDATA.FYSTATUS)=7 Or (CASEDATA.FYSTATUS)=8))
GROUP BY IUIDCODES.CODEDESCRIPTION
PIVOT CASESTATUSCODES.CODEDESCRIPTION;

To calculate the percentage of the number of passengers in the total number of passengers per single order using query:
Code:
SELECT
Code:
A.Date, A.Plate, A.Pax, A.Agency, A.Code, IIf ([pax]> 0, Round ([Pax] / (SELECT Sum (Pax) FROM Sheet2 as B WHERE B.Date = A.Date and B.code = A.code), 2), 1) AS KOR
FROM Sheet2 AS A
ORDER BY A.Date;
Query works fine in all cases except one, and that is when the encounter a same order in one day
01/04/2013. D_1 0pax
01/04/2013. D_1 5pax
in this case the formula gives a coefficient of 1 to 0 passengers and coefficient of 1 to 5 passengers, should be given a score of 0 0 of passengers and 1 to 5 passengers

I've just made this query at work, it brings up the results from a database of telephone surveys. about going all gestapo on the table names and codes, I'm unsure as to how told off I could get for placing identifiable images on the internet
query.png
basically I would like to extend this query so it shows the sum of the "CountOfQ1 22" column and also shows what percentage of that total each entry in the "Q1 22" column is.
This will enable me to have results for the day sent to me at home every night at close of business as the person supervising the call centre at the time can run the query and email me the results.

In one of my queries I calculate a percentage based on a change from one year to the next; however, sometimes there will not be any prior year data hence the percentage is undefined (i.e. current year amount/0=undefined). To stop the query from displaying an error when this is the case I wrote the following:
CapitalSurplusChange: IIf([P/Y Operating Data]![CapitalandSurplus]=0,"N/A",(Nz([C/Y Operating Data]![CapitalandSurplus],0)-Nz([P/Y Operating Data]![CapitalandSurplus],0))/Nz([P/Y Operating Data]![CapitalandSurplus],0))
I have the properties of the field set to percentage, but the calculation does not display as a percentage but as a long decimal. If I take out the Iif the percentages display fine however there are errors for the undefined calculations (hence why I inserted the Iif). How can I amend the code above to only display the "N/A" answers as text. I know about the formatpercent function, however I am exporting this output to excel and this when using the formatpercent or formatnumber operation the data still displays as text and not a number. Any ideas?

I have a Query that gives me the output as follows:
Code___DateofReview___Response___CountofReponse
AAA____12/19/2006_____0_________3
AAA____12/20/2006_____1_________2
AAA____12/20/2006_____0_________1
AAA____1/4/2007_______1_________2
The Field "Response" can either be 0 or 1. The Variable "Countofresponse" gives me the Count of response when it is 0 and 1 for a given Date of Review.
How do I modify this query so I can get a Percentage value added to this list. I would like to see the following result but not sure how to arrive at this:
Code___DateofReview___Response___CountofReponse___ PercentValue
AAA____12/19/2006_____0_________3________________100%
AAA____12/20/2006_____1_________2________________66%
AAA____12/20/2006_____0_________1________________34%
AAA____1/4/2007_______1_________2________________100%
Can anyone help please?

If you take a look at my DB, you will find I have have MANY queries made. Is there an easier way to find this kind of information?
Any suggestions would be appreciated.

Hello All,
I am not sure what I am doing wrong. I am trying to get a percentage of two numbers and the expression is not comming out right. This is the expression:
Expr1: [Ontime PU.CountOfP Performance]-[Late PU.CountOfP Performance]/[Ontime PU.CountOfP Performance]
Here is what it should do:
1242-68/1242=0.94524959742351046698872785829308 (which would be 95%)
For reason it is not doing this?????
Any Ideas????
Thanks

In a report, I need to calculate the percentage of clients that respond "Yes" to a question on a survey. I need to create a query that will return the count of the number of "Yes" responses, and the number of total responses.
For example, if 10 clients complete the survey, and seven respond "Yes", I need the 2 fields in the query to be 7 and 10. So far, I have only been able to do this using multiple queries.
Thank you.

For several days now, I have been trying to write an expression, in a report, to get a percentage. I am new to Access so I don't completely get it yet. This is the expression I wrote (only works sometimes):
=[pathjbo50]/([pathjbo50]+[pathcol50]+[pathpp50])
This expression only works when all the fields are populated. If any of the fields are empty, I get nothing.
Please help!
