Random Database Results
I am using the following code to Query information from my db table. The problem I have is that it displays the whole table rather than displaying 5 random results by ProductID.
<%
objConn2.open strconn2
Set objRS2 = Server.CreateObject("ADODB.Recordset")
objRS2.Open "SELECT * FROM Products", objConn2
Do While Not objRS2.EOF
Response.Write ":: <a href=""productsDisplay.asp?ProductID=" & objRS2("ProductID") & """>" & objRS2("Product_Description") & "</a><br>"
objRS2.MoveNext
Loop
objRS2.Close
objConn2.Close
Set objConn2 = Nothing
%>

I'm trying to create a portion of script that would select x (variable) number of random records from a table.
in PHP, I could do this pretty simply with a line like, "select * from table order by rand() limit x", but the solutions I've seen so far for asp and access involve things like 40 lines of code, selecting the entire contents of a database, creating temporary tables, etc.
Is there any quick and dirty way of doing this?

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....

What I want the funstion do is to generate a code which is not in db?
How can id do this?

There are 26 prizes available in a competition a client is running and he wants to be able to select these at random.
I thought the best way of doing this would be to construct a simple ASP page which displays 26 random records from the database.
The fields I wish to display are called name, email and address, and these are located in the table called Competition (this is an MS Access db).

I'm not sure if this is possible or not, but I thought some one here should be able to tell me how it can be done. I'm building a site that will allow people to enter information about their company into a database, the information is then displayed in a profile page for them. They can enter things like news and events. This all works fine and dandy, but now I have had an idea.
Is it possible to be able to publish something for each company so that they can display the same information on their own website? I am thinking it would be something similar to an RSS feed.
Has anyone done anything like this before? The site right now is ASP with a MSSQL backend. The sites that will be posting the published information may be a variety of hosting platforms, if a certain platform is required then we will make it as a requirement.

I am trying to retrieve images from the database and display them in a random order. The order of the images is supposed to change each time page is refreshed.

rResult.Open sSQL, strConnect
if not rResult.EOF then
do while not rResult.EOF
response.write("hi")
imgID = imgID + 1
img(imgID) = "images/tiles/" & rResult("TileImage")
response.write(img(imgID))
rResult.movenext
loop
end if
if not rstResult.EOF then
intVendorID = 0
do while not rstResult.EOF
if intVendorID <> rstResult("VendorID") then
rndNumber = RandomNumber(imgID)
Response.Write "<p>"
Response.Write "<a href=javascript:popWin('tileview.asp?" & rstResult("TileID") & "','',1,1,1,1,700,600);>"

I am trying to write an array of random numbers to a database. The array part is working fine, but when I go to update the dataabse, it inserts the last value of the array into all the fields in the database .....
Dim MyValue,sqlRandom

for i = 1 to 8
Randomize
MyValue = Int((100 * Rnd) + 1)
arrayRandom(i) = MyValue
response.write "<p> Array Value:" & arrayRandom(i)
sqlRandom = "UPDATE CarParkDetails SET FreeSpaces = '" & arrayRandom(i) & "'"

I am using a repeater control to display the results of a database query. The problem is when outputing the results of a multiline nvarchar field.
I generally try put it in a <pre> tag and try to enforce the table width. However this doesn't help and the table width when viewing the page is the width of the page, and not the specified width. Code:

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>

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:

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?

I have a client asking me about random images on his site, basically I am using the following code:-
<%
RANDOMIZE
Response.write("<IMG SRC='../gfx/bg-img0" & INT((3)*RND()) & ".jpg'>")
%>
Agreed its not the best code, but he is finding that the same image could be repeated like three times in a run.
I have an include file which displays the image, and the random script is placed inside that include. So when he is going from page to page this is where the issue lies.
Can anyone help me out here, is it even possible to have a different image load each time, and not have them repeating.

I am using random number to be used as a unique identifir. Since random numbers are in decimals I am using going to convert it into an integer and since I need to append this Id into my URL, I am converting it into a string. SO my formula looks like this.
CStr(Int((Highest-Lowest+1)*Rnd+Lowest))
S0 now every time a new record is generated would this formula generate a unique number for unique identification in the table. I can't see how it can do it. Say A user is assigned a random number; then another user subscribes so how would the server determines that the random value assigned to next user is not already assigned to any other user.
In case if this can't work (a unique ID for every user) then I'll stick to this very same formula and after the random number is generated, I'll check this number with the table in the database and see whether it's been assigned already. If yes, I'll request another random value, if not then I'll go with it. Is this the right strategy?

I have the below ASP function to display a random image from a folder.
<%
Function RandomImage(strPath)
Randomize()
If Right(strPath, 1) <> Chr(47) Then strPath = strPath & Chr(47)
strPhysical = Server.MapPath(strPath)
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder("C:Inetpubwwwrootpag-siteimages
andoms")
Set objFiles = objFolder.Files
For Each objFile in objFiles
strFile = LCase(objFile.Name)
strFiles = strFiles & strFile & vbTab
Next
strImages = Split(strFiles, vbTab)
If UBound(strImages) > 1 Then
RandomImage = strPath & strImages(Int(Rnd(1)*UBound(strImages)))
End If
End Function
%>
and this places the image in the HTML
<img name="Intropic" src="<%=RandomImage("images/randoms/")%>" width="211" height="158" alt="" />
but sometimes the script places a ._ before the image file name in the outputted HTML?

I'm afraid I have a technical problem here. Basically what happens is that I'm getting some random errors(like Type mismatch... etc) that shouldn't under normal circumstances occur. Then I connect to my server via remote desktop and Recycle the application pool on which my asp pages run. Errors then disappear
