Another Median Query

Jan 3, 2007

Hi,

I am trying to run queries to determine the median values for different age groups of peoples each with different illnesses. At the moment the database asigns an age group for each person whos age falls into the module determined age brackets, under 16, 16 - 40, 41-50 etc.

For each age group and diagnosis (bronchiectasis, sarcoidosis or pulmonary fibrosis), I need an age distribution chart including the min, max, mean and median.. min max mean are all simple enough and using MS VB median module I can individually calculate medians for each of these. The problem comes when trying to combine these all in one data set.

One solution I found was to combine two reports so I have queries with min, max, mean and then the medians set up beside them. The problem tho with this is that when a recordset returns 0 results (i.e there are no people under 16 with sarcoidosis), the query linked to the report does not return the value of 0 but as they dont exist it does not include it at all. The median fields however return blanks and cos of this the line spacing becomes messed up and the report becomes incoherrant and incorrect.

I think the solution will have something to do with querying, though so far I have not been able to work it out :confused:

Please help!

Calculate Median In Query

May 3, 2006

Hello:

I have read the Microsoft article at http://support.microsoft.com/kb/q95918/ several times. However, I am looking for an expression I can place in the field name to calcluate the median of another field in the same query. Is this possible? If not, I don't understand how to call the function created in the Microsoft article.

Example (fields in the query)
Expr1
Expr2:Median(Expr1)

Thanks in advance.

Group By In A Median Query

Apr 24, 2007

I've gotten the medianf fuction that is pasted on these boards working in the attached db example. The problem I am running into now is the medianf function (correctly) takes the median for an entire table at once. My dataset example looks like:

typenum
t11
t12
t13
t16
t16
t1100
t21
t22
t2200

I'm trying to end up with median t1 = 4.5, t2 = 2. With the way that function works, it sets them both to 3 which is the median of the entire set. I have the query saved in here already setup so far. Any ideas on getting the grouping to work properly?

OK try this:

I want to get the Median number from the "This Week" column for Cher. The output should hopefully tell me that Cher has a score of 7.

In addition to this.. I want to be able to create a report which tells me the medians for all the artists in the sheet.

Modules & VBA :: Calculate Median Value For Group Of Transactions Within The Same Industry?

Oct 15, 2013

I am using the code below to evaluate values for each transaction to determine the median:

Function MedianF(pTable As String, pfield As String, pgroup As String) As Single
'*******************************************
'Purpose: Return median value from a recordset
'Inputs: ? medianF("Values", "Industry") <enter>
'Output: results are currently incorrect
'*******************************************
Dim rs As Recordset
Dim strSQL As String

[code]....

The code generates median results based on the value but not the correct ones, as I check results in Excel using the Median function. I need to see the median for the transactions within the same industry and I do not know how to do that . Below are some sample transactions including the Industry, Value, mymedian (which the current results based on my code) and the expected median result (which I calculated in Excel based solely on the transactions listed here). Note that mymedian results listed in the 3rd column are determined using the complete data set (over 2000 transactions). I only included a few sample transactions below to show that I am currently getting 2 different median results: 44.62 and 50.82. Also be aware that I do not want to evaluate any zero value transactions, which I believe I am handling in the strSQL line above where I indicate <>0 . I need to see a Median result for each industry and the result should be the same for all transactions within the same industry.

Industry Value mymedian Expected Median
Aerospace 18.01 50.82 40.45
Aerospace 53.02 50.82 40.45
Aerospace 109.18 50.82 40.45
Aerospace 61.54 44.62 40.45

[code]....

This is how I am passing the values from the query to the module, passing the value of Period2 if Period 1 = 0, else passing Period1:

mymedian: IIf([Period1]=0, medianF("qry_My_Query","Period2","Classification_I ndustry"), medianF("qry_My_Query","Period1","Classification_I ndustry"))

Query In Forms Question (printing A Single Selected Query Record From A Form?)

Oct 19, 2004

What is the best way to impliment a query in a form so that the user can view the query records, and have the option to print or save the selected record using command buttons?

I tried subforms but I could not get the command buttons to work in the subform after it went into the form, it wanted to print the entire form instead of the selected record from the subform.

So in a nutshell I have 3-4 queries that are built, and I want to have them show up on my form in a format that the user can scroll through the results and select a single record of the results and then print or save that individual record from the form, if such a thing is possible.

Thanks in advance

Queries :: Join Results Of Unmatched Query With Matched Query To Include Null

Mar 24, 2013

I am trying to do the good 'ol sales report (query) to include customers with no sales.

I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)

If I run a query to show customers (in the customer table) with account numbers, that works

An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).

How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?

I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?

Queries :: Opening Design View Of Append Query Without Timing Out Source Query

Mar 4, 2015

In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.

All is well and fine until source data changes and the pass-through query runs too long and times out.

If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table

Is there a way to open an Append or Make-table query in Design view without invoking the source query?

UNION Query MS Jet Database Engine Cannot Find The Input Table Or Query.

Oct 28, 2005

Hello All,

I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".

Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.

I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

SELECT SalespersonID, Sum([SlsPrice]-[RtnPrice]-[SlsDiscnt]+[RtnDiscnt]) AS fldPrice FROM MyTable WHERE (((Source)='d') AND ((DistrictID)='01') AND ((CategoryID) = 'HCPROD') AND ((BrandID)<>'CSS')) AND (((BrandID)<>'1356')) AND (((BrandID)<>'1400')) AND (((BrandID)<>'1551')) AND (((BrandID)<>'555')) AND (((BrandID)<>'66'))
AND (TransDate >= 07/01/2005) AND (TransDate <= 07/31/2005) GROUP BY SalespersonID
UNION
SELECT SalespersonID, Sum([SlsPrice]-[RtnPrice]-[SlsDiscnt]+[RtnDiscnt]) AS fldPrice FROM MyTable WHERE (((Source)='d') AND ((DistrictID)='01') AND ((ProductID) = '0029800')) AND (TransDate >= 07/01/2005) AND (TransDate <= 07/31/2005) GROUP BY SalespersonID

Queries :: Export Query To Excel Then Delete Query Data From Table

Nov 20, 2013

I am wondering if there is a quicker way to export a query to excel then have the data in that query removed from the original table. (effectively cutting the data from the table and exporting to excel)

I understand that this can be done by exporting the query to excel then running the same query as a delete query to remove the data but I just wondered if this is the most efficient way.

I have experience of VB in excel but currently only use the basic macro builder in Access though if Access VB is more efficient I can easily learn.

Queries :: Update A Query Based On Results From Another Query Using Count Function

Apr 2, 2013

I run a physical therapy office and patients come in for treatment either 3, 4 or 5 times per week. My database is used to track these frequencies (among other things).

I have 3 queries which count how many patients come in 5, 4 and 3 times/week.

In my main table I have fields called "how many 5's", "how many 4's" and "how many 3's".

I have tried to design an update query which will update those fileds in my main table to reflect the counts in the 3 queries mentioned above.

(I'm not using SQL view, I'm using the query design view)

In the "update to:" row, I use the Build function and locate the count I'm looking for.

Problem: when I run the query I get the error: Operation must use an updateable query.

Queries :: Crsosstab Query Doesn't Recognize Expression In Source Query

Aug 12, 2015

I have a query where these are the fields:

ProductRevType
RevLag
RevFlowThru
CloseMoYr
ProjRevDate
CurrentMRC
ProjRevMRC

The ProjRevMRC field is an expression that reads:ProjRevMRC: IIf([ProjRevDate]>=DateSerial(Year(Date()),Month(Date()),1),[CurrentMRC]*[qry303a_ SFADetailMRC_ONLY]![Rev Flow Through],0)

When I run the query, it works perfectly, but when I created a crosstab query to show totals by month, I wanted the totals to be zero for the months less than the current month. Is there a way for the crosstab query to execute the expression and put zeroes for those months?

I have a form which will be used as the basis to print a label.

It is bound to a query and when I open the form I pass over a 'where' condition to return 1 record. I then use the query to produce a report/label.

What I want to do is to update the form/query without updating the underlying tables to the query.

Blank Fields In Crosstab Query Based On Previous Query

May 31, 2006

:confused:
I am trying to help someone with a complex problem (so it seems to me) but I will first ask about what should be a simple thing....

First goal: to COUNT the number of times a TYPE of visit is made.
There are several different TYPEs but only interested in tracking 2 of them.

When a crosstab query is created - if one of the 2 parameters are not "met", a blank is returned. I have been reading posts about using NZ and IIf IsNull, etc to get past that - but none of them make any sense to me and the Access help suggestions do not work. Hope someone can make it clear with this information: (can't give more specifics to keep privacy intact)

The SQL was written by Access not by me. :)

Here is an example of the Crosstab SQL (which is using a previous query):

TRANSFORM Count([qryTest2.TYPE]) AS CountOfTYPE
SELECT qryTest2.CID
FROM qryTest2
GROUP BY qryTest2.CID
PIVOT qryTest2.TYPE;

-----------
qryTest2 SQL: (Grouping by to remove dups)

SELECT DISTINCTROW tblM.CID, tblM.[M#], tblM.LNAME, tblM.FNAME, tblM.YMDBIRTH, tblC.ClDOS, tblC.TYPE
FROM tblM LEFT JOIN tblC ON tblM.[M#] = tblC.[M#]
GROUP BY tblM.CID, tblM.[M#], tblM.LNAME, tblM.FNAME, tblM.YMDBIRTH, tblC.ClDOS, tblC.TYPE
HAVING (((tblC.TYPE)="Out" Or (tblC.TYPE)="In"))
ORDER BY tblM.CID, tblM.LNAME, tblM.FNAME;

Thanks for you time! :)

Show All Records From One Query And The Sum Of A Field In A Related Query Record

Mar 8, 2005

I'm building a report for annual software license renewals. The report data source is a query that combines the customer information, their computer information, and the licenses purchased for that computer. I am having no trouble with the form displaying the customer info page, then a page with the computer info at the top and a list of licenses purchased for that computer underneath.

That would be great, if that's what my boss wanted. However, she wants the whole list of available licenses displayed on each page, in the event someone want to purchase additional licenses with this year's renewal.

I'm trying to figure out how I can set up a query/report grouping to do that. I've tried making a new query, relating the qryLicense!licenseID to the qryPurchase!purchLicense and setting the relationship option to show all records from qryLicense and only those related from qryPurchase. I added the qryPurchase!purchCPU field to my query, hidden it, and set the criteria to “=1” (the computer ID of one of my dummy computer records). I also have a Sum of the qryPurchase!purchQty field included in the new query that I want to display the total number of that particular license purchased (and 0 if there are no corresponding records). All fields except for the quantity field are set to Group By.

What I’m getting from this is simply a list of the licenses purchased for that computer, not the complete list of licenses available showing the quantity purchased where applicable.

Can someone see where I’m going wrong?

Queries :: Query To Insert Missing Rows From Another Query / Table

Oct 8, 2013

I am using an Access 2010 DB to keep track of a schedule. Essentially, at least one person needs to be signed up to work for every hour of every day in a week.

Tables:
Days with 7 records
Hours with 24 records
Workers with as many people that sign up to work the different hours
Schedule signifying the worker, day, and hour which are signed up.

As of now i have a query that relates these results and gives me a line detailing the worker/time information for the slots that are signed up for.What I'm TRYING to do is to create a query that gives me BLANK worker info when there is no one signed up for a particular hour.Currently my Schedule table has the following:

WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
16 | 5 | 15


What I'm looking to do is have this table matched up with another table (or query) that provides every combination of day/hour. When an day/hour combination is skipped, the query will be able to "fill in the blank" with a row. Like this:

WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
| | 14
16 | 5 | 15

Queries :: Query Error When Data Changes In Crosstab Source Query

Aug 12, 2014

I have a database which among other things records how jobs are received i.e.: Telephone, Email, Mail, Facsimile or Web.For each client I want to identify the percentages of each method of receipt against the total of jobs received and during different time periods.I have created a make table query for all jobs received between variable dates for a client entry of the name of the client and the start and finish dates are required to run the query.

I have a crosstab query set up to count each method of receipt and a final query to work out the percentages using the total from the crosstab query fields divided by the total of all methods.I have a macro set up to replace the table with new data when I want the stats for a different client between new dates, therefore the different methods of receipt may vary for the less active clients i.e.: they may only have telephone and email .

My problem is if I choose a client where we have not received a job by a particular method (say web or facsimile), the last query working out the percentages has fixed names to cover each method but naturally produces an error when it cannot find a corresponding method of receipt. I have experimented with NZ() without success.My question is can I either have preset standard names of the column field in a crosstab query? Alternatively in the query calculating the percentages, can I include code to ignore a non-existent field in the crosstab query.

Query Is Too Complex... On Report, But Query Runs Fine

Oct 18, 2005

Hi...

I have a query that when I run it normally (just click on it) then it runs fine. (It is a union query, getting it's data from 8 other queries (who has their dependancies)

But when I want to run a report from it, Access gives me an error saying "query is too complex".

I am flattered, but I would prefer access to work than say I write stuff that is too complex for it. :cool:

Any ideas?

I am confused by the fact that it runs when I double click the query, but the report bugs it out.

Syntax Error In Query. Incomplete Query Clause

Sep 28, 2005

I am really stuck. I have spent two days searcinh different forums trying to solve my problem. I am trying to create an UPDATE q to my Access database. But I get either the: "Syntax error in query. Incomplete query clause" or "Syntax error in UPDATE query".

First of all here's the URL: www.innotec-as.no/login/Kunder
Login U/P either: "alfen" or "thomas".

The page opening up shows the user info, U/P and adress.
viewing the information is working perfectly - but editing it..no way.

When editing and submiting the data the above errors occour.
Try that and you'll also see the SQL I am trying to execute.
The CODE is as follows:

SQLtemp = "UPDATE 'Brukere' SET"
SQLtemp = SQLtemp & " 'navn' = '" & request("Navn") & "', "
SQLtemp = SQLtemp & " 'epst' = '" & request("Epst") & "', "
SQLtemp = SQLtemp & " 'Pass' = '" & request("Pass") & "', "
SQLtemp = SQLtemp & " 'Firma' = '" & request("Firma") & "', "
SQLtemp = SQLtemp & " 'BAdresse' = '" & request("BAdresse") & "', "
SQLtemp = SQLtemp & " 'BPostAdr' = '" & request("BPostAdr") & "', "
SQLtemp = SQLtemp & " 'PAdresse' = '" & request("PAdresse") & "', "
SQLtemp = SQLtemp & " 'PPostAdr' = '" & request("PPostAdr") & "', "
SQLtemp = SQLtemp & "WHERE 'Bnavn' = '" & request("Bnavn") & "'"

Response.Write(SQLtemp)
Response.End()

conn.Execute(SQLtemp)
rs.Update[/COLOR]


The finished SQL statement looks like this:

UPDATE 'Brukere' SET 'navn' = 'Alf Byman', 'epst' = 'alf@baccara.no', 'Pass' = 'alfen', 'Firma' = '', 'BAdresse' = '', 'BPostAdr' = '', 'PAdresse' = 'sdfg', 'PPostAdr' = '', WHERE 'Bnavn' = 'alfen'

I have tried to user single quotes, doubble quotes, brackets etc. nothing works.

The code I use for connection is as follows:

<!--#include file="../adovbs.inc"-->
<%
dim conn, rs, SQLtemp

' DSNless connection to Access Database
set conn = server.CreateObject ("ADODB.Connection")
rs="DRIVER={Microsoft Access Driver (*.mdb)}; "
rs=rs & "PWD=uralfjellet; DBQ=" & server.mappath("../../../../db/kunder.mdb")

conn.Open rs

I'll be very HAPPY for some expert help on this.
