Queries :: Create And Order By Random Number In Query Field
Jan 2, 2015I'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?
Queries :: Access 2007 - Update A Field In A Table With A Random Number / Long Integer
May 27, 2014Is 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.

Creating A Random Number
Jul 8, 2006Quick 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.

General :: Random Number And Comparison
Oct 22, 2013Anyway, 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.
Modules & VBA :: Generated Random Number Always The Same
Jun 2, 2015I 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
Random Number Generator For Customer Drawing.
Mar 9, 2006My 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.

Modules & VBA :: Random Number Sequencing Based Off Of A Certain Criteria
Aug 21, 2013I 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.
Queries :: Adding New Records To Table - Random Number No Duplicates
Jul 31, 2013I 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.
Create Random Number To Be Automatically Generated As Default Value For Record ID
May 28, 2015I'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.
Create Random Member ID Field?
Nov 3, 2004I have a database that I took over for a small group (it has about 400 records), and they want to add a field for "Member ID", to use for member badges and whatnot.
A friend tried to help me by suggesting the "Change the starting value of an incrementing AutoNumber field" from the Access Help File, but I don't necessarily want incremental numbers, I just want a string of perhaps 8 numbers in no particular order, and obviously, unique to each record. I also don't understand how I can get that to work in pre-existing records...
So, what I'm wanting, in a snapshot, is:
83928475 John Smith 123 Any St
93827221 Mary Jones 678 Market St
19182734 Elvis Presley Graceland
etc...
I was thinking that perhaps a formula could be created in a query? Heck I don't know!
I only know enough about Access to be dangerous, so I appreciate anyone's help!
THANKS!

Random Generate Into A Null Field...
Apr 19, 2005First off, I want to see if this is possible. It seeems like it should be but sometimes I dream bigger then things allow.
OK... I have a form made in Access. There is a text field that I would like to be able to do the following:
If the field is null, a number will be randomly generated betwen teh values of 1 and 1500.
If the field is not null (we entered a number between 1 and 1500), then that field would be set to that number.
The field CANNOT have the same number given (we will only have 1500 records and want them randomly generated a number unless otherwise specified).
Can this be done? I made my attempt but it keeps failing no matter how I try and fix and such. I guess this is what happend when you haven't used Visual Basic in about 4 years.
PLEASE HELP! Thanks In Advace,

So each line (each row) spreads on to 2-3 pages to the right.What I would like to do is make the namebar, on top of every column, a little bit higher, so the name would be split into two lines, or three.
