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 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?

Function To Select 3 Random Numbers Which Are Distinct
I need to generate three random numbers between 1 and 100, but they need to be different.
e.g. 3,43,88 would be fine but 5,76,76 would not.
The function I have to generate a single random number is:
function funRandomNumber(intHighestNumber)
randomize
funRandomNumber = int(rnd * intHighestNumber) + 1
end function
called by: funRandomNumber(100)
Can anyone see how this can be modified to do what I need?
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.

theRandom= Int((99 - (0) + 1) * Rnd + (0))
if (theRandom<10) then theRandom = "0" & theRandom
RandomNumber = theRandom
end function

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:
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?
Error Using <select></select>
I have written some code which should dynamically build a table which is then populated with questionas and possible answers. The format of the answers will vary ie they may be in the form of a radio button which will be rated from 1-5, checkbox or a selectbox.
The first problem I have is if I do not comment out <select></select> I get an error message saying the page can not be found. when I do take it out I get asp timeout. Code:

Regarding Random
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.
Random Value
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?

Random Image
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?
Getting Random Errors
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

View Replies View Related3 Random Records From DB
I want to take 3 records from a database. The selection must first take any record marked as priority and then random records (so there could be 3 priority records and no more or 1 priority and 2 random etc)
My theory is to build a recordset filtered by records marked priority, and if there are less than 3, build a second recordset of all the other records.
Questions
1, how can I select random records form the second recordset, without selecting the same one twice?
2, OR, could I write a sql statement which would randomly select 3 records from my table
3, Or is they a way I could write a query (view) in Access which would do the whole lot for me (select the priority records and then random records up to 3)?
Random Code

but for some reason it sometimes saves code as an empty string. When I register a fake name, ie zzz, it seems to work fine, but for some of my members is saves as an empty string.

I have a problem creating random numbers. I basically have this
