Hi,
Can you please help me out--give me some guidance-if you have knowledge about random numbers. Say, for instance, I have 2,000 records and I want to randomly create a final list with 800 of these records, how do I go about it? Thanks.
Hi Guys,
In my table design view I've set my primary key to auto number and the 'New Values' to random. The problem is, sometimes the numbers generated are too long or negitive. Is there any way I can specify the limit of the numbers to be generated and keep them positive numbers?
Hi all,
I am having one table with id from 1 to 50. Now I want to return random records from that table using rnd.The point is that is there any funntion like
Select [id] from tblids where id not in (values) with rnd
Thanks in Advance

Please Help, I need this ASAP!
Any help will be very much appreciated!

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
How to generate random project numbers that reset automatically every month? I want to generate project numbers that look like this:
1234/06/12
where the 06/12 stands for the month and the year while the 1234 is a randomly generated number.
I want the random number to be four digits long.
I already have a number of projects with similarly generated projects from an existing database. Can I import these projects without changing their project number?
I'm having multiple problems with my database like things such as -
i'm currently working on the Query 2 - On the Phone database (ignore Query 1) and i want to search for multiple plot numbers preferably in one parameter prompt with a comma to seperate numbers. (this could be a multitude of numbers so i would like to be able to input as many as needed). Also when i do search on this query since the Criteria is a 'Between' Value i would expect everything between the 2 numbers input to show up - but a lot of numbers out of the range show up too - why is this? (The Numbers are like "69 to 136" and they will show up - but 1-69 and 136-170 would too
I would also like to implement the search results from Query 2 into the Form i currently have made but it just opens up a access table when the search is made?
i cannot link my database as it is too big for the server - But here are the Criteria for Query 2:
Plot No - (criteria = Between [Enter First Plot No:] And [Enter Last Plot No:])
Site - (criteria = Like "*" & [Enter Site:] & "*")
Product - (criteria = Like "*" & [Enter Product:] & "*"
The Query is the one im most concerned about , i can live without a form.
Ok so in excel I have some numbers that are stored as text. The reason being that they are zip codes and some begin with 0 and excel doesn't want numbers to start with 0....so when I import these into an access field that has an input mask for zip codes...will it convert these correctly since the field is a text with input mask?
View 1 Replies View RelatedI have 2 fields that I would like to automate if possible
One field is called "p/o number" and another field called "line no"
These fields are part of an ordering database
Let say I have 200 items to purchase form 10 suppliers
And form example 20 items from each supplier
What I do at present is put the order number on each line item and the line number
example
p/o number line no
1 1
1 2
1 3
2 1
2 2
2 3
2 4
What I want to do is just put the first po number in the required line . Put the first line number in i.e. "1" and the macro will complete all the p/o numbers and line numbers for me as per the ones marked in red.
Example
1 1
2 2
3 3
2 1
2 2
2 3
I have a small unbound form which has a txt box with code something like =Rnd((20-1+1)*Rnd()+1)) to generate random numbers. When the db and form are first opened the field always contains the same number. Using F9 to refresh will generate another number but it is always the same too.
If the form is closed then reopened (db is not closed) the field will happily generate a random number each time the form is opened or if F9 is used.
I have tried Recalc in numerous events but each time it failed to work. It's late at night here so I'm hoping the morning will bring a clearer outlook???
Has anyone got any suggestions? :confused:
Was playing around, and when using the
Code:Me.txtNum1.Value = Int((51 - 1 + 1) * Rnd + 1)
format, I noticed that, with 6 differnet text boxes, that after opening the database, the "random" numbers repeat in the same order. That is, with 6 randomly generated numbers, the first set is always the same and the second the same and so on.
Why is it not really random?
Hi, I have a DB that is basically a big electronic form. Each table is a section of the form and the main central table stores the ID's from the other tables. Most of the relationships are one to one but without referential integrity because sometimes sections need to be skipped.
It's been growing fairly rapidly lately as bit's keep getting added but now a weird deletion problem has started appearing. Every once in a while when a user goes to complete the form (right at the end) it suddenly dissapears. The records in the related "section" tables are still there but the main table storing all the ID's loses the record.
There are NO cascade update/delete's on any of the relationships, also no-error message appears it just goes. I think there is a problem in actually saving the record because I moved a DoCmd.RunCommand acSaveRec command from the complete button to a slightly earlier process and the point at which the record dissapeared also moved.
Does anyone know what may be causing it? It only happens to about 1 in 30 forms and there is no obvious link between the problem and
a) the machine it happens on
b) the person using it
c) the data entered into the form
If it happens the same user can input exactly the same data in exactly the same way and it saves it fine.
It really is random!
People are starting to get really frustrated. I was tring to "sell" the idea to a new department as well and had 15 people sitting in front of a projector when it happened to me. I was mortified :eek:
Any ideas would be greatly appreciated.
thanks,
Tom
Hi,
everything was going fine until a random error appeared and now wont go away.
here is my code
MainFormPay()
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = " Payment Numbers" ' name of form t open
ANumber = [LastOfVerificationID].Value ' set value of latest Verify number
stLinkCriteria = "[ContractorID]=" & me.ContractorID ' filter to contractorID
DoCmd.OpenForm stDocName, , , stLinkCriteria
Docmd.GoToRecord, , acNewRec
Forms![Payment Numbers]![VerificationID].Value = ANumber
end sub
this was working fine but now i get the following error message:
Run-time error '40036'
Method 'Item' of object 'Forms' failed
when i debug, it highlights the line
Forms![Payment Numbers]![VerificationID].Value = ANumber
the purpose is to get the LastOfVerificationID value from form 1 and then open Payment Numbers, create a new payment number, set verificationID to the new value. this was working fine and without even woring on the forms code, this error has arisen.
how can i fix it?

With Access 2003 I have a tbl_Orders with the field OrderID set as Autonumber>Long Integer>Random. This produces long strings of numbers both positive and minus. Is it possible to set a certain format such as #### and no less than 0 but no more than 9,999?
View 3 Replies View Relatedhi everyone,
i have a query which returns n number of rows. my problem is that i need to display the values in text box which is created automatically according to the number of rows returned in the same page(form).
for example if my query returns 1 row then 1 text box must be automatically created and then the value must be displayed and if my query returns 3 rows then 3 text boxes must be created and then the corresponding three values must be displayed.(on the same page).
is this possible?

I'm looking for a way to generate a random list of 25 case numbers from a table which contains 500case numbers. Can someone tell me how to do this.
View 1 Replies View RelatedQuick question, how do I have access generate a random number between 1 and 8? I want it to generate either a 1,2,3,4,5,6,7, or 8. (no zero, no nine)
Expr1: Fix(Rnd(8-1)*10*Rnd()) is what I have been using, but this always generates the number 2? I do want the decimals to be rounded to the nearest integer, thus I have Fix.
If someone could please help me, it would be greatly appreciated! Thanks in advance.
Hello,
I have a very complex issue.
First of all there is a table called "tblParTeam" wich contain the teamname and ID of teams partissepating in a certain Tournament. The tournemant data is kept in the table tblTournament.
Each tournament contains a couple of variables: "Number of teams per tournament", "Number of Rounds" wich reside in the tblTournament.
Here is the thing. I also have a form based on the tblTournament. Each tournament had a number of partisipating teams (stored in the variable "Number of teams per tournament"). Then I have a table called tblTournamentDetail wich containt the Tournament_ID, TeamPro_ID (looks in the table "tblParTeam"), TeamContra (also looks in "tblParTeam").
When I pusch a button on my form, wich is based on the tblTournament, tblParTeams and tblTournamentDetail, I would like the X (Number) of particepating teams to be filled in randomly in the tblTournamentDetail.
Lets say I have 10 teams I want 5 to be filled in randomly in the TeamPro_ID and 5 in the TeamContra_ID.
How do I go about this?
Thanks in advance.

Hi Guys,
I hope someone can help with this. I have a table, "Blasthole Submission" which is populated by input in a form, using the code below:
Const MyTable As String = "Blasthole Submission"
Const MyField As String = "Sample Name"
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim intCounter As Double
Set db = CurrentDb
Set rs = db.OpenRecordset(MyTable)
For intCounter = Me.txtStartValue To Me.txtEndValue
rs.AddNew
rs.Fields(MyField) = "TP" & intCounter
rs.Fields("Submission #") = Me.SubNum
rs.Fields("Sample Type") = "Blasthole"
rs.Fields("XRF") = "True"
rs.Fields("LOI") = "True"
rs.Update
Next intCounter
rs.Close
db.Close
Set rs = Nothing
Set db = Nothing
What I am hoping to do is to place a random duplicate in the table, called, for example TP111152 DUP, approximately every 50th record. Is there any easy way of doing this?
Thanks in advance for your help!
Hi all
I would like to find out if there is a program where you can randomly select data out of a table?
I sit with a table with 17000 SKU's(codes and data) and need to randomly select items out of it for Stock Count's:confused:
Thanx:rolleyes:
Hello all
this is my first post, so i hope i'm in the right bullettin.
I need help with this problem:
I have to work on this mdb that has been imported from Access 2000 to Access 2003. The guys did it some months ago, and of course they deleted the old .mdb and there are no backups.
However, the db still works, except that the ID of some tables are now "random id" than "incremental id", and since they used it for some months, now they are full of new records with random IDs.
Since they use THAT id for internal use, you understand that is not very easy to communicate stuff like "please send me document # -3189175187" and so they asked me to get it back to incremental, i tried from the table menu to change the dropdown, as i thought it was that easy. Bad luck, access now complains that the data aren't now contiguous (might be different error, it's a localized version, so i don't know how it is the exact error message, sorry), and i'm not really sure on what to do to avoid problems.
I've explained the best way i could, so if you need more info just ask, thanks everyone in advance!
Hi all,
I am not real sure whether or not this can be done with a query, but here goes.
I have a query randomly selecting the top 6 from a selected group.
SELECT TOP 6 tblConsortium.ContactID, tblConsortium.RandomID, patients.LastName & ", " & Patients.Firstname AS [Employee Name], Contacts.Company AS [Company Name]
FROM patients INNER JOIN (Contacts INNER JOIN tblConsortium ON Contacts.ContactID=tblConsortium.ContactID) ON patients.PatientID=tblConsortium.PatientID
WHERE (((tblConsortium.ContactID) In (SELECT ContactID FROM tblConsortium GROUP BY ContactID HAVING Count(*) <25))) And (((tblConsortium.PatientID)=Randomizer())=0)
ORDER BY Rnd(IsNull(tblConsortium.patientID)*0+1);
What I would like to do now is: The randomly selected Employees need to have a randomly selected TEST. There are only 3-Test to choose from. I have placed the TESTS in a separate table and entered 20 of TEST1, 4 of TEST2, and 1 of TEST3. I then set a query randomly shuffling these items. I need these TESTS to randomly be assigned to the randomly selected Employees above.
I would greatly appreciate any thoughts or help…
Thanks Enviva
Hi,
Can someone please help. I am required to bring back a ranadom 10% of data where the [Total_Cost] field is less than £500.
Can this be done in one query? I have to use Access97 becuase this is the lowest Office Version we support.
:confused: .
This is my first post. Please help me.
Here's my DB :
Status : Number (Long Integer)
Random : Number (Double)
If Random value is around 0-0.9, the status value is 1
If Random value is around 0.9-1, the status value is 0
Here's my Query :
UPDATE DB Set Random = RND()
Rnd() give random value, but each records have the same value,
let's say 0.71212154
How can I update all records with random value,
with a single query ?
