General :: Random Number And Comparison
Oct 22, 2013
Anyway, here is what I am looking to do:
1.) Generate a random number between 1 and 100 and assign the result an identifier, like a person's name.
2.) Generate a second random number between 1 and 100 and assign the result a different identifier, like another person's name.
3.) Compare the two randomly generated numbers.
4.) Have the identifier of the LARGER random number displayed on the screen.
I would like to have this linked into a button click.I am hoping there is an easy way to accomplish this task.

I am working on a form and need it to be able to generate a random number to use as an invoice number. The only parameters i need it to meet is that it is at least 5 digits in length. I was hoping i could use a button to make the number generate in a separate box.

Quick 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 this query:
SELECT UNIT.Code, Rnd() AS Expr1
FROM UNIT;
The problem is that in the Expr1 field all the numbers are the same. I would like to have random numbers that are different for each record (generate new random number for each record)
Thanks for your help
Cheers

Ok, I apologize in advance for my lack of knowledge but I need Help!!
I have a database form that has a O_Num field that populates the Order table. Now the client wants the order number to be a randomly generated number. this is the primary key and I cant use autonum because there is another field in the table that is autonum.
I have tried to use the following in the OnClick field, doesnt work
=Int((1000 * Rnd()) + 1)

Hello i've got to make a project for school and thought I would make a rental shop like Blockbuster. But I need to create a number that will be assigned to each customer when they become a member. So I need to generate a random number that uses a certain amount of digits (I was thinking about 8) and that won't be used again can you help.

I'm using Access and VB for the first time, trying to develop an application for hobby use. I built and populated my database, and I'm building my first module. Unfortunately, one of the most simple actions is tripping me up. I'm attempting to perform an action only if a 255-character text field in a file doesn't contain data, but comparing it to " " or "Space$(n)" doesn't yield the actions I'm expecting.

I have a log in screen that my users must use before they can use my db. if they enter the wrong username/password they get the usual message boxes. I also thought it would be a nice personal touch if once they've logged in they get a little greeting, so i made a message box that says "Hello " followed by their first name
This did the trick for a while, however theyre sick of seeing "Hello" and want other greetings, i figured this wouldnt be too complicated and took me only about 10 minutes or so to implement.
Basically i created a table (tblGreetings), has two fields, an autonumber field (ID) and a short text field
I've added the following code into the login sequence:
Dim greetings As Integer
Dim greet As String
Dim randomNum
greetings = DCount("ID", "tblGreetings")
randomNum= Int((greetings - 1 + 1) * Rnd + 1)
greet = DLookup("Greeting", "tblGreetings", "[ID]=" & randomNum)
which in theory should generate a random number between 1 and "greetings" (which is an integer representing the number of greetings ive stored in my table), currently greetings=9
then it should pick a greeting from tblGreetings using the random number as an ID
This more or less works, except whenever the DB is opened and a user logs in, the "random" number is the same every time, it always seems to be 7 (which corresponds to the greeting "G'day").
Why this random number is always the same? it changes if i run the code a few times in the same session, but once the database is closed and reopened it still gives off the number 7, every time

On an Access database, I would like an ID number to be generated randomly.
This ID number needs to be within the range of 11000 - 99999.
How is this possible?

My company does daily, weekly, and monthly drawings using mountains of entry tickets and a barrel that has seen better days. So needless to say this system has to go. I hope to be able to do it digitally.
I would like to do a random number generator to pick the winners based off of a ticket number range. The ticket numbers issued to the customer would correspond to the customer account number. To complicate things I would really love to have the random numbers displayed on the screen so people feel they are watching the randomization pick in progress with the winner name popping up.
I have searched Help for Rnd function, as well as googled. I haven had any luck finding what I need. Is what I am looking to do possible in access? I had something similar in Excel a few years ago but lost it.

Hi.
I have major report due within hours.
I need to add a field to existing table that will be a 9 digit number, non duoplicating or - to take an existing field of 9 digits and allow it's values to change to random or incremental, non-duplicate numbers of 9 digits. I already have an autonumber field I must keep.

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.

I have a form which allows the user to add new records to a table. After the user had entered all the information into the form, they click a command button to add the record. In addition to adding the new record, my command button runs an query which is supposed to generate a random number between 1 & 1,000,000,000 and update the record ID field with that number.
Here is the formula I have been using in the "update To" now of my query: Int((1000000000-1+1)*Rnd()+1)
My problem is that I keep getting duplicates. You would think that the chances of getting a duplicate number would be pretty small with this large of a range, but I get a duplicate almost every time.
I have tried indexing (No duplicates) the field in the table, but that did not work. When my query generated a duplicate number, the record was just not added to the table.
I also tried a two step approach:
1-Make a table of all in use record ID numbers from my table (tblIdNo)
2-Update new record with a random number that is not in tblIdNo
This was a no-go too
How to build an update query that will update each new record added to the table with a random number between 1 & 1,000,000,000 without any duplicates? This seems like it should be so simple, and I am starting to get really frustrated.
I would prefer to accomplish this through a query/queries (if possible) rather than with 100 lines of code. This database is not for me, it's for another group, and the individuals in this group are totally freaked out by code.

I'm trying to create a query that generates random numbers for each record, sorts them by that field, then selects the top record. This should randomize the record being selected.
I can use the Rnd([ID]) function which does appear to generate a random number. Problem is that each time I exit the program and come back in, it always selects the same record. When I remove the Top = 1, to show all the records, every row does have a different random number but it does not appear to be sorting by this field.
If I run the query, here is the number I get: 0.98609316349029
Exit the program, restart, and run the query again: 0.98609316349029
If I refresh the query, the second and third time does appear to be random but the first result is always the same. how to generate truly random numbers?

I've been building a CRM in Access that allows for creating profiles for our accounts. When we add a new account, I'd like an Account ID to automatically generate and look like this: CRMXXXXX where the X's represent a random number. I originally wanted to set the field as autonumber to just count up, but unfortunately I need to append this value to another sales database we have; you can't store the text "CRM" with an autonumber in a table.
Right now, all I've done is place an equation in the default value of a textbox I have on my 'Add Account' form. I then made the control source of the text box the Account ID field. My equation is as follows:
="CRM" & CStr(Int(Rnd(Now())*10000))
This appears to work, as it generates a value in the correct format. However, I've realized that each time I open the CRM, the random numbers start over again and I run into issues of trying to create a new record with the same ID as a previously created record. I assume I need to incorporate some sort of timestamp to it in order to change it.

Is it possible to run a SQL command to update a field within a table with random numbers?
More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.

I'm sure it's not random, but it doesn't seem to follow any sort of rules. My database has become "Read Only" 3 times now causing all workers using the database to stop work until IT can fix the issue. All IT does is kick everyone out of the folder that my db is in and suddenly it is no longer read only.

I have almost all of my info with the exception of few hundred pieces of data entered into my database. After looking it over and looking for ways to improve it, would it be easier to import all the tables into a brand new database and starting fresh with everything? I have made a lot of changes since the inception of the database so there are forms and queries and reports that no longer work because of the changes. Or should I go back and change them?
Also, if I am looking to join to tables can they be joined by their foreign keys? They are listed below:
tblEmpInfo
EmpInfoID <PK>
EmpIDFK <FK>
JobNumberFK (joined to tblJobs)
EmpType
CraftCode (would get rid of this)
tblEmpRating
EmpRatingID <PK>
EmpID <FK>
EvalDate
SuptID
StatusChange
CraftCode
I want to join the tables based on the EmpID can this be done or do I have to add another field to EmpRating ID?

I pulled a report from this website my company uses and it has around 7,000 orders and a corresponding employee to each record. Since each employee has around 20-50 orders, I was wondering if there was a VBA code or different Access tool to randomly select only 2 orders from each employee, thus reducing the data set from 7,000 to a more manageable number?

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 have a table with an auto number PK. This table will contain orders. I'd like to use the PK from this table as the Invoice number on the invoice. I'd like to have it start at a number other than "1" just because it looks better on an invoice. I don't know how to do this. I looked at the table design to see if there were options available to me there but couldn't find anything. Is it possible? (I do not know how to use code.)
