Random Record Selection Error
I'm trying to create a piece of code that randomly selects a record from a database (providing the record has not already been chosen for any of the previous 4 sections).
Here is my code:

Random Record Selection
i have an access database with 5 records in and i need to show them in a random order every time the page is refreshed or reloaded. i've searched round and tryed no end of code but nothing seems to work.
i just need something really simple that selects a random feild from my DB. Sql = "SELECT * FROM tblmain ORDER BY RND()" - ive tryed this and it just shows the results in teh same order.

I have an access database, and in a table is the field "names". There are over 100 different values in this field. I was wondering if it was possible to connect to the database and randomly select 1 of these names from the field and display it.
View Replies View RelatedSelect RANDOM Record
Ok here is what I'm trying to do. I want to grab a random record from a specific table. This is how I am doing it now:
x = 0
Set rs = Conn.Execute("SELECT Count(*) as total FROM [user] WHERE active = '1'")
If rs.EOF <> True then
total = rs("total")
End if
Randomize timer
randnum1 = int(rnd * total)
If randnum1 = 0 then
randnum1 = 1
End if
rs.close
set rs = nothing
Set rs = Conn.Execute("SELECT * FROM [user] WHERE id = '" & randnum1 & "' ")
Now that would work fine, BUT the id is a autonumber int of 1.
Now look at this example. Let's say I have 50 records, so I have the ID values of 1 through 50. Now I delete record number 46. So now my count goes up to 49. So the random number will pull up ANY number between 1 and 49, so if it pulls up 46 then BAAAM record can not be found.
There has to be an easier/more efficient way of getting a random record. I don't plan on deleting any records, but I just don't feel this is the best way of doing this.
Random Record Retrival
I want to create a record set for all the products in my database, i then want to randomly select some of them each time the page loads and display them, these have to change upon each refresh.
any ideas
my final problem i will post seperatly however, heres the score if any has any ideas.
ive created a product database of bikes, they have diferent sizes and colours. at the moment i am having to display each individual record. rather than having a single record and then on the detail page being able to have a dropdown menu or a choice of sizes there?
How To Choose A Random Record From A Database
ill have a database with 1 table and 3 fields:
ID FIRSTNAME LASTNAME
(the ID field will be the auto incrementing index)
there might be 10 records in the DB, there might be 10,000. i need to open the DB and randomly select a record (and then display the name, which i dont have a problem with)
how can i randomly select a record? im guessing id have to open a recordset and check the count to get the number of records, so lets say there were 100 records. i imagine i would have to generate a random number between 1 and 100....
9 Random Records - Returns All But First Record In RS
I have been using this script which basically works fine, with on hitch. I populate a recordset from a database. Then, use the total number of records as a UBound.
I then want to display 9 random records. I get my 9 random images, but for some reason, if I do a sort by ID on the database, the lowest numbered ID file never comes up in the list. Here is my code: Code:
Random Record With SELECT TOP Does NOT Work
<%
Dim oConn, oRS, randNum
Randomize()
randNum = (CInt(1000 * Rnd) + 1) * -1
Set oConn=Server.CreateObject("ADODB.Connection")
Set oRS=Server.CreateObject("ADODB.recordset")
oConn.Provider="Microsoft.Jet.OLEDB.4.0"
oConn.Open Server.MapPath("temp.mdb")
oRS.Open "SELECT TOP 1 EMAIL_ADDRESS, r = Rnd(" & randNum & ") FROM TABLE1 ORDER BY r", oConn, adOpenStatic, adLockReadOnly
Response.Write oRS("EMAIL_ADDRESS")
oRS.close
oConn.close
Set oConn = nothing
Set oRS = nothing
%>
this gives the error: "No value given for one or more required parameters".
what i would really LOVE is for someone to fill in whatever required parameter im missing, but more important i would like to understand whats going on. there are people who go through life dumb and happy once something "works", but i need to understand how and why its working. even if this code did work, im confused with the SELECT statement (no, i dont have much SQL experience aside from basic queries). what is the "r = Rnd" line doing in the middle of the querie? how am i ordering by r?? also, i dont have an indexed, primary "ID" field in this databae. is that ok for this code to work?

Random Error: Too Few Parameters. Expected 1.
I needed to create a quick and simple "lock-in" system where many people in a computer lab can pick an answer (A, B, C, etc.) and then the results be displayed to me. I went looking for a free ASP poll script that would work for my needs. I found one called Poll Manager on AspPlanet.net (http://www.aspplanet.net/viewdl.asp?itemid=6). It gives me the ability to see the results with a bar graph of sorts and easily reset the data. I have everything set-up and working, however, I modified the results page so that it reloads using javascript every 5 seconds. After letting the page reload several times, I get the following error:
Microsoft OLE DB Provider for ODBC Drivers error '80040e10'
[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
I can reload the page and often the error goes away, but sometimes it takes a few reloads. What could be causing this? The code can be found at aspplanet.net but I can also copy and paste it here if needed. Any ideas?
Error Inserting New Record
I am receiving the following error when attempting to insert a new record into my database
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again.
The code below works 1st time through, but on the 2nd invocation (with TOTALLY different data), I get the above error message.
My database is an Access 2003 database, and everything else works fine !
Also, if I'm really trying to write a duplicate record, why doesn't it fall into my duplicate trap? Code:
Record Insertion Error
A page I'm working on contains a registration form which is supposed to a) update an Access database using ASP and b) email the contents of the submitted form to the camp administrator.
This is my first experience with ASP, and with any kind of database interfacing language, for that matter. Currently I'm struggling with the record insertion. I'll worry about email afterwards.
I'm using Dreamweaver 8, which is generating all the code for me. I have a testing server set up on my local machine (in my working directory, in fact). I've told DW to connect to the databse (located in %siteroot%/database) through the testing server using a DSN (same DSN as on the web server). Code:

this involves one ASP page, two tables and one SP. Here they are: Code:
Updating A Record - Getting An Error
I have a very simple Access database with these fields:
ID | Team | Score
I want a user to enter the new score of the team into a form and then it's updated. All pretty straighforward - except I'm getting an error at the bottom of this page:
ADODB.Field error '800a0bcd'
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
/forensic/update.asp, line 171
And when I submit the page I get this error:
Duplicate Record Error Message?
I have a booking form, called classroomform. On this form the user requests a classroom number, location, date, start/end time and number of students.
As it stands, the data is submitted via a submit button and an insert query created using Dreamweaver.
I already have various validation on the form, such as javascript which error checks for invalid times etc and asp validation which checks for correct dates etc.
However, the final touch that I'm looking to do is to add some code to the form which checks for duplicate entries that are in the database. I basically want an error check which doesn't allow the user to enter a duplicate record that is based on classroom number, location, date, start/end time.
Here's my code: ...
ADO Record Set Error Number -2147467259
Code:
SELECT * From Product WHERE CatId = 14 AND CatSubId = 13 AND CatSubSubId = 9
Now if i change this query to either of the below it reults in an error as nothing is puled from the database. Now if i run this query directly in Access, these 2 execute fine:
Code:
SELECT Size From Product WHERE CatId = 14 AND CatSubId = 13 AND CatSubSubId = 9
Or to
Code:
SELECT Distinct Size From Product WHERE CatId = 14 AND CatSubId = 13 AND CatSubSubId = 9
Size is a number (long integer) field.
Err.Number is -2147467259
Err.Description is blank. no description
Err.HelpContext is 5003251
I have increased the script time out and command time out time and still the same thing.
How Do I Make Random Images Not Random?
However, what I want to do is include a request.querystring("ID"), so that IF an ID is defined, eg ID=3, , it will display the relevant (not random) information. I've tried this every way I can think and get type mismatches, etc etc. It's probably really simple but I can't see it.
<%
limit=3
redim link(limit)
redim image (limit)
link(1)="xxx"
image(1)="image1.jpg"
link(2)="xxx"
image(2)="image2.jpg"
link(3)="xxx"
image(3)="image3.jpg"
randomize
random=int(rnd*limit)+1
%>
<center>
<a href="<%= link(random) %>">
<img src="<%= image(random) %>" border="0"></a>
Making It Random (getting Random Numbers)
I just wanted to know whats the best way to generate 50 or say X amount of number at random without having to repeat any of the previous number...
so far I've the following:
[VBS]<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<%
function RandomNumber()
dim theRandom
Randomize
'RandomNumber = Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
theRandom= Int((99 - (0) + 1) * Rnd + (0))
if (theRandom<10) then theRandom = "0" & theRandom
RandomNumber = theRandom
end function
%>[/VBS]
and then I've this in the body of HTML doc: Code:
Random Token Generator - Not Really Random
We have the need to have a random token (a 16 char alphanumeric field) to be used as the key for one of our SQL tables. I have created a random token generator, however after only 3 months in production, it appears that we had an instance where a token that already existed in the tables was created. There are 3810 records currently in the database so it isn't like there are billions of records there.
I contacted an old college buddy of mine who is a mathematician, and he claims, assuming that random really does mean random, that the chances of getting a duplicate token are 1 in 79.5 septillion (79,500,000,000,000,000,000,000,000).
So my conclusion is that this was either a complete freak of nature occurance, or my random generator isn't really all that random. Here is the code behind how I am generating this: Code:
Apostrophe Error While Retrieving The Record From The Database
I am using a Replace function to replace single quotes with double when
submitting a text field in the database i.e. Replace (q, "'", "' ' ")
which works fine. When I retrieve the field from the database which has
apostrophe I am getting 'Object expected' error message. Is there a
way to fix this?
Single Record In Array Produces Error.
I get a "Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

error when running following piece of code:
set RS = Conn.Execute(strSQL)
DS = RS.GetRows()' -- (this is line 200)
RS.close
Conn.close
set RS = nothing
set Conn = nothing
If the recordset has two or more records in it, it works fine, but if the recordset has only record in it, I get the error. Code:
Random Number Not Random
I am trying to generate a random number. I am using randomize and then rnd to return a decimal number between 100 and 120. This will give me a longitude. I am doing something similar to generate a latitude.
I created this on a page which refreshs every minute. I put these points into a map and they are showing up in groups of straight lines. Since rnd is time based will refreshing every 60 seconds return similar numbers?
Selection
i want to do a voting, which let user select. how can i count the number of user vote?
n... how can i accumulate each slection and display a chart by percent?
example:
.apple
.beer
More Than One Selection
I have a web page where a user can select a location out of a possibility of 5. I also give them the option of seraching all 5.
However when I put this in it get rids of the drop down box and puts them all in an open box about 2 inches in length. Which isn't too bad but if I say had 20 locations it would take up half the page.
