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'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:
How do i select a completly random record from a database?
sql = select (random) from tbl, sort of thing.
How can i retrive random row of table in ASP.i have a table created in

I have a field in my access db called StreetName a single record would contain one street and I want to return all records that have a StreetName in the Streets field. How would I go about this?
I have a DB with 10 items and an SQL statement:
"SELECT * FROM myTable WHERE Activate=true"
How do I make it so that every time the page refreshes it will display a random record?
Is there a simple code I can use in order to get a random record from a access database in ASP ?
View Replies View RelatedI 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 RelatedOk 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.
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?
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....
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:
<%
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?
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
%>

<a href="<%= link(random) %>">
<img src="<%= image(random) %>" border="0"></a>
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:
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'm getting this error message: Error Type:

i want to do a voting, which let user select. how can i count the number of user vote?

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.
I do not write the whole code.
I have a IF statement like the following.
if request.Form("UyeTipi") = 1 then

I am working in an asp/Vb script environment.In a form I have 2 combo boxes.first is main criteria and second one is sub criteria.in the first combo I have made predefined enteris(the headers of the table)say a table is:emp and its headers are:empid,empname,L1manager,accounts,location etc.
on a change event of first combo,I want to fetch the details from the table.say if I selected Ename in first combo.the second combo should automatically fetch the listed Enames and vice versa.
My left frame contains a combo box which loads the selected record in the main frame.The combo box retrieves concatenated 3 columns from my db. E.g. ID, Firstname & Surname.
Because of this, it seems to blow out the size of the frame,thus ruining my nav system.Does anyone know how I can restrict the box width, but allow the drop down part to remain wide?
I have searched through a lot of paging articles. But I have not found any specific recommendations for my issue. I have a large record set that I need to page through (1000 records). But on each page (100 records) I must be able to select some rows, add
some comment for each and sumarize them on-the fly.
if I page forward and backward, I still need to see before selected rows with comments and I can even deselect or edit some of them. Should I store all this information (selection, comment, price) in session variables or is there a better way?

My site is running on IIS5.0 hosted on win2k service pack 4 m/c. We are going to procure high end windows M/C . I seek your advice in selecting right os and version of IIS. My comp is a bit hesitant to migrate to .net too (I don’t know planning of comp in future).My requirement should be
1) Same Program should run on new server with minimum changes.
2) If required we can migrate to .net (although planning is not in near future and I even don’t know what is needed for that)
Your advice in this regard is highly appreciated. Also if you can explain in short about new feature in IIS6.0 (or upper version). Which version of IIS come along with Windows 2003 server, I really have very little knowledge in this field.

I have a selection list of the 50 states that is not dynamically built. If &state=CA is in the query string i want the selection list to automatically select CA out of the selection list since that is what was in the querystring. Know what I mean?
View Replies View RelatedHas anyone used the UPS e-tools such as address verification and rate selection service? I'm trying to implement it on our site and I would just about kill to see some source code. It's a little above my coding level and I just can't seem to figure it out.
The documentation goes into a VB sample, but I dont think that is necessary since you can perform an HTTP POST and parse XML in an ASP page.
