Select Equal Type - Based On Random Query
Oct 6, 2006
Good Afternoon Everybody,
Apologies for imposing on you all but I was wondering whether or not you could help me out??
Would you be so kind as to kind as to show me a practical example of how to incorporate a facility into my attached Database which serves to select an equal ratio of my field “SectionHeadings” such that out of the 30 “random” questions that it currently generates it will provides me on completion with the following:
5 From Set1
5 From Set2
5 From Set 3 …..etc etc
It currently generates the 30 questions that I need without a problem; however it routinely selects any number of one particular type, sometimes more from one subject and less of another.
All subjects headings are of equal importance to me and as a consequence would be very grateful if you could look at what I’ve already done and show me what needs to be done in order to achieve my aim.
I hope my request is possible - Any help you could give me would be very much appreciated. Thank you very much.
Best Regards
CarolW

As part of my job, each month I have to select 20 problem report resolutions and grade them on quality. Typically we have about 100 problem report resolutions per month. Is there a way I can use a query to return a random selection of 20?
Thanks,
Jim

I have to review 20 reports each month for quality check. I have a query that lists the reports completed within the past 30 days. Is there a way to filter this query to show only 20 random records?
If there is no way to do this, can you suggest some way of doing this so that it's impartial? For example I don't want to select the first 20 of the month because everyone will catch on and wait late in the month to post their report. Normally about 70 reports are completed in a month.
Thanks,
Jim

I am fairly new to Access 2013 but am trying to create a query that will select random records from three totally unrelated tables and display the results together as if one table -- think video slot machine wheels. Each table has two fields - ID which is the primary key and NAME. The data in the tables are names of states, names of colors, and types of animals. Each table has a different number of records. My end result is a table that selects X number of random records from each table and displays them side by side like this:
Desired Result:
Animal Color State
cat red Ohio
dog blue Texas
fox green Iowa
I have been able to create three individual queries that will pull X number of random records by using:
SELECT TOP 10 Animals.[ID], Animals.[Name] FROM Animals ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 Colors.[ID], Colors.[Name] FROM Colors ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 States.[ID], States.[LongName] FROM States ORDER BY Rnd(-(100000*[ID])*Time());
Using the three queries above I get three separate lists. how to make one query that will randomly pull from all three tables and make the display above?

I am trying to run a query where one field has a Not Equal parameter AND another field has Not Equal parameter (for example, Product Code Not Equal "A" AND Client State Not Equal "NY)
The result of the above query are all records that have Product Code = "A" are missing from the result. I want some of the "A" Product Codes; I just want to exclude the ones where the Client state is NY.
The list of values for each field is too big to state it in a positive way (I would have to list all the other 28 product codes and all the other 49 states).
What am I doing wrong? Thank you in advance for any suggestions.

Is there an easy way to auto-populate a Junction table [in access 2010] given the following two tables with a many-to-many relationship for Tasks? The two tables are
Table 1) tblTasks (TaskID (PK), Description), and
Table 2) tblMeasures (MeasureID (PK), Description, Tasks)
If JCTN table is JCTN_Tasks_Measures (TaskID, MeasureID), is there a way to populate when tblTasks(TaskID) == tblMeasures (Tasks)?

Hi,
I am trying to write a query that looks at a set of parts that are assigned to the same "Asset" number, and takes the sum of all prices for that collection of parts.
I have the query set up to do this without any problem. Where I am stuck is that in the table containing the details of parts, there are three possible prices. What I need it to do is take price c if there is no value in prices b or a, price b if there is no price in price a (otherwise take price a).
I have tried this using the criteria ="price a" = 0 AND "price b" = 0 (for price c)
and ="price a" = 0 (for price b criteria). When I run the query I get a "Data type mismatch in query expression" error.
Can anyone advise?
Thanks,
Ryan

Hi,
I would like to run a simple select query, where the CRITERIA is based on the user choice.
I have a form with a combo box, with a few choices, and a button that will trigger a macro with one query for now. I can store the choice in to a variable e.g. "town", using Microsoft VB code.
How can I transfer the variable to the CRITERIA field in the query, so whenever I chose a specific "town", my query will select the records for that specific town.
I want to use one query, and I don't want to have to "hard type the criteria in to the cells' query", but I would like to use a variable that can change and will be read it from the user choice through combo box.
If I am not clear enough, please let me know.
Thank you!

I have a RN generator that looks at 9 different lanes and puts in a number based off of a certain criteria but I was wondering if in the frmLanes the actual "Go" button was an incoming number how could I get my current random number generator to look at that number and determine if the current number is within 5 of the "go" number?
Any way to have a beginning number that I would enter into a text box and have the number generator kick off based off of that number. I have included a copy of my db for viewing.

Hi all,
I have a query which populates a form called EditPatientFrm, which asks the user to enter the patient UniqueID in order to pull up the record they want to edit from the TblPatient. However, I want the user to now be able to input just one of three criteria in order to pull up the record to be edited:
UniqueID
ChartNumber
PatientLastName and PatientFirstName (two fields)
since they may not have the UniqueID readily available to them.
Can anyone show me how to do this? I have tried to find answer to this one under queries and forms- no avail. Sure it's a simple thing...
thanks!

I'm having trouble with my VBA module.I have a random test generator which pulls records based on a category from my table into a temp table using a make table query. I use the following code:
Private Sub Command2_Click()
DoCmd.SetWarnings False
DoCmd.OpenQuery "1", acViewNormal, acEdit
DoCmd.OpenReport "WrittenExam", acViewPreview, "", "", acNormal
Reports!WrittenExam.lblTitle.Caption = "Exam Name"
DoCmd.OpenReport "WrittenExamAnswerSheet", acViewPreview, "", "", acNormal
Reports!WrittenExamAnswerSheets.lblTitle.Caption = "Exam Name - Answer Sheet"
End Sub
My querry makes the table, and then generates two reports (my exam, and the answer sheet). I'm getting an error 3211, saying the temp table is already in use by another process when trying to generate both reports. I used a Macro before, but I have a need for custom report headings, so I'm using VBA.

Is it possible to run a basic select query to pull records based on multiple strings entered by a user?
I have a query with field criteria - Like '*' & [Type In MMDBID:-] & '*'
This allows the user to input one MMDBID and the records are retrieved from the db.
I can also use the OR statement in the same field criteria "AB123" OR "BC123", and all records based on those values are pulled back.
But I cannot get the user to input multiple values and I tried amending the SQL string based on the OR criteria above
SQL statement (Like) is below :
SELECT tblFund.MMDBID, tblFund.[Investment Name], tblCodesLive.[IOE Code], tblCodesLive.[Uptix Code], tblFund.[Red Payment Deadline]
FROM (tblFund INNER JOIN tblCodesLive ON tblFund.MMDBID = tblCodesLive.MMDBID) INNER JOIN tblContact ON (tblFund.MMDBID = tblContact.MMDBID) AND (tblCodesLive.MMDBID = tblContact.MMDBID)
WHERE (((tblFund.MMDBID) Like '*' & [Type In MMDBID:-] & '*') AND ((tblFund.Editing)=False) AND ((tblFund.Closed_Fund)=False));

Hi,
I'm trying to create a count on a tick box of products that have been reviewed, however, the SQL statment I am using (as I have for a couple of other counts will not work fo this dues to 'Data type mismatch' which I can only presume is due to the fact that is is a tick box....
SELECT COUNT (TechnicalServicestbl.RequestID) AS TotalAwaitingReview
FROM TechnicalServicestbl
WHERE (TechnicalServicestbl.[Current Status] = "Completed") AND ((TechnicalServicestbl.[Review]) = "No" )
I have used the same template for a different count of completed jobs of the day, which works fine so far as I can tell.
SELECT COUNT (TechnicalServicestbl.RequestID) AS CompletedJobsToday
FROM TechnicalServicestbl
WHERE (TechnicalServicestbl.[Current Status] = "Completed") AND (TechnicalServicestbl.[Date Complete]=Format(Now(), "mm/dd/yyyy"));

I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2]
FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following:
[table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as:
[table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
I appreciate your help in advance.

I have Table as PL2008 and RPT2. Both tables have one column named PTUNID. My goal is to first Group, sum certain Columns in the PL2008 then match PTUNID from this Grouping to RPT2 Table's column PTUNID and then show the results which do not match.
I have written following Qry but what really happenning is its giving me all the results ( match and no match in both tables ) and Sum values are incorrect.
SELECT [PL2008].PTUNID, Sum([PL2008].[Total Hours]) AS [SumOfTotal Hours], Sum([PL2008].[Actual Cost]) AS [SumOfActual Cost], [PL2008].[PRFIELD]
FROM RPT2, [PL2008]
WHERE RPT2.PTUNID <> [PL2008].PTUNID
GROUP BY [PL2008].PTUNID, [PL2008].[PRFIELD];
Any suggesstion
Thanks

I have a query that uses a linked table from an external database and joins it with a table from my database to return records that contain the same values.
Is there a way to return only the records that are present in the external database and not in my db?

I have a table that contains many records of events. I've already created a multiple item form based on the table. My form contains 2 textboxes for input of a date range and a dropdown box to select "yes or no".
What I am having difficulty with is the query that will count the records by type insert it into the recordsource such that the multiple item form will appear like this:
Event Type| Count
Input | 4
Output | 2
Update | 3
How do I go about doing so? I have been testing with this simple query:
Code:
Private Sub Command8_Click()
Dim Task As String
Task = "SELECT EventType, Count(EventType) FROM Final GROUP BY EventType;"
Me.RecordSource = Task
End Sub
But the column that contains the count keeps appearing as #name?

I have created a make table query and using expressions for two of the fields. I have set the field properties (format) to "Percent". The expressions are calculating rates based on two other fields. The expressions are currently as such:
PTD_CM_PGM_RATE: IIf((IsError([PTD_CM_REPT_PGM]/[PTD_CM_REPT_ER])),"0%",[PTD_CM_REPT_PGM]/[PTD_CM_REPT_ER])
I'm using the IIF function to avoid potential errors should one or both of the values ("PTD_CM_REPT_PGM" or "PTD_CM_REPT_ER") be zero.
However, when running the query, I am getting the "...type conversion failure is caused when the data in one or more fields doesn't match...." error.

I have a table with RandomID, EmpID, CompanyID. Some Companies will have great than 25 employees. I need to setup a query where I can randomly select all employees from all companies whos employee count is less than 25.
I have tried the following:
SELECT top 10 percent Count(*), empID
FROM tlbCompany
Group By empID
HAVING Count(*)<25
ORDER BY rnd(RandomID);
This counts the total number of employees, so if a company has 10 employees, it will only display one of the them.
Can this query be done?
And, what am I doing wrong?
Thanks to all that help....

The queries go like this at present :
SELECT TOP 1 [Table].[QuestionText], [Table].[Answer] AS CorrectAnswer
FROM [Table]
GROUP BY [Table].[QuestionText], [Table].[Answer], rnd([IDQuestion])
ORDER BY rnd([IDQuestion]);
SELECT TOP 3 Table.Answer AS Correct, qQuestionTextAndAnswer.QuestionText, qQuestionTextAndAnswer.CorrectAnswer
FROM [Table], qQuestionTextAndAnswer
WHERE (((Table.Answer)<>[qQuestionTextAndAnswer].[CorrectAnswer]))
ORDER BY Rnd([IDQuestion]);
These queries are displayed now in an Access form "frmQuestions" which is applied to "Table" that has three columns id, text , and answer. The result is one question and four suggested answer with one only being correct.The arrangement of the answers is randomized--
but the choice of the question is not realy random....it always starts with the same question as it relies only on rnd.
can I improve the queries and randomize and rnd in the same ...or else can I switch these queries to be used from vb6 code and achieve that result.
any help would be appreciated.
By the way I am really a beginner at this who is seeking help from the experts.

Hello Everyone,
Im trying to make a query which will allow me to run a query update so that all my listings will get a new random number generated for them,
Ive got it selecting any listing with a ID of >0 (so basically thats all of the listings)
What id like it to do is then assign a random number to the randsort field, (prefer a number like 0.812 or 0.342 etc etc)
To start with ive tried using the Rnd feature, but its updating all the listings with exactly the same number (though granted the number changes each time the query is run)
I see in some of the other comments regarding rnd that you may need to put a randomize statement somewhere,
Im very new to programming in access and was just wondering am I on the right track, and if so where abouts should i declare the randomize code since its in a query?
Thanks for your time and look forward to your replies
Cheers Ezy
