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....

i have a database with one table... there are about 10-20 records in the table. i would need to create a page that displays a few descriptive fields of the records. just something like this.
ID NAME PRICE
1 type1 345
2 type2 567
3 type4 1000
just a simple list like this in a table, also each record would need to act as its own hyperlink, so when clicked on. using the primary key i presume, it loads another page specifically for that record. almost like a catalogue..if someone could please direct me to a few tutorials or online examples of this kind of procedure.

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.

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.

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?

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?

Things are ok on these points:

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).

Is it possible to set the sessionID = value?
I am storing a shopping cart in a in a temporary table and with the sessionID identifying which items belong to the different users. Ideally I want to set it to a random GUID or number so it will make it very hard to guess the next session ID and gain access to another cart if they knew what they were doing.
Any ideas on how to set the sessionID value? Do I need to go that mush in to detail?

I've just had a problem with an ASP page not connecting to one of our Oracle databases. It turns out that the web server has Oracle 8.1 and Oracle 9.2 installed and that my
ASP page was trying to connect with Oracle 8.2. The TNSNAMES.ORA file for this version of Oracle is not maintained and did not have the correct entry I need.
Is it possible to force my ASP pages to use Oracle 9.2 until the migration is complete and Oracle 8.1 is removed?
My connection string looks like this:
Session("PROVIDER") = "Provider=OraOLEDB.Oracle;Data
Source=ht;User Id=" + Request.form("username")
+ ";Password=" + Request.form("password")
