View Replies View RelatedI have 30 numbers. I need to select randomly 10 out of the given 30. A number must not repeat ( eg. i can't have number 10 twice ). How can i do this??
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.

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 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)?
I know how to generate random record from a database, the problem i need to overcome is like this:
1.If the user refreshes the page is a way i can control the randomized data from not repeating itself on display?
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?
I have read 10000 opinions on returning random records and I am more
confused now that before I started. I have a small access db that will
contain 20 or so rows with 3 or 4 columns. I like to return a set of 6
distinct rows and display the columns in html. I have seen response.write
and loops but can't I throw the 6 random rows in a array and pull the data
as I need it in the page? Examples?
I have this page where I want to display 3 random pictures in a vertical table. Each picture represents a record in an Access database. The field "picname" holds the name of the picture (e.g. "pic1.jpg", "pic2.jpg", etc). Each record has a unique ID. How do I go about selecting these 3 records? I want the pictures to alternate everytime someone enters the page or refreshes it. I found a couple of javascript options, but they only choose the picture from within a folder, and I need to be able to link the pictures to each record.I don't know if I made myself clear enough.

i am currently working on an online test tool using ASP. Now, the questions would be generated randomly from a database(access), so two or more candidates will not have the same question. There will be one question per page. Now, i have successfully generated the radom questions from the database.
But i have a problem which is:
1. When i click the next link to go the next question, my code displays the question on the previous.
2. Also, when i click on the previous link to go back to the previous question my code changes the question from the previously answered to a new question. Code:
Im looking for a very simple and small script that will display 2 random records for a database, but i havnt found one yet. Can someone help me on this one?
View Replies View RelatedI'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?

I have two different news tables. I can't get any of them and list.
Bu i want to do something different. I want to get both and randomize them and list them.

View Replies View RelatedI know there are plenty of threads relating to 'random' records, but non of the code samples seem to return random results each time I refresh the page; or don't show any results at all? The ID numbers for my recordset are not necessarily consecutive numbers (some items may have been deleted). I simply want to feature 2 or 3 random news teasers on my home page WHERE feature="yes". I guess I need to call 3 random id's, and keep looking until a record is returned? I would also like to change the number of 'teasers' displayed via another database table - I can do this later, but the code has to accommodate a flexible way to change how many records are returned.
Here's the Access table:
news (TBL):
id
title
shortdescr
longdescr
feature
If you have a possible answer for me could you please provide sample code and spell it out clearly.

Still working on my soccer database, I have a list of 100s of teams and want to give users various ways of accessing the information. One of those methods would be via a drop down box which would have

On the homepage of my site I want to show an overview of the three lastest submitted newsmessages.
How can I do that without loading all the news fields (overload)?
eg. select * tblnews where date1,2&3 closest to now();
I display work request records from a db table into a .html table dynamically by cycling through the db table until RS.EOF.
To the right of each record displayed I have two checkboxes, "chk_dev_accept", "chk_dev_sendnotif". These are the only editable items on the page.
"chk_dev_accept" is clicked by the developer to assign the work request to his/herself.
"chk_dev_sendnotif" is clicked if the developer wants to notify the customer that the status of the job has changed (optional and automatic - I don't have a problem with this part).
Upon clicking the "Update Record" button, I want the records with the checkboxes clicked to update.
The db record fields that would be updated are: "dev_developer" (The developer that will do the job, read from a cookie) and "dev_proj_status" (changed to 'Assigned'). These two fields should update when the "chk_dev_accept" is clicked and form submitted. I want the developer to check as many records as he/she wishes.
My problem is I'm not sure how to code that <input checkbox....> tag, and then, how to take that checked value to select the appropriate records to update.
Is this do-able with ASP / VBscript?
-- I have a database with user records (name, photo, etc. etc.)
I want to use asp to generate (on the homepage) a series of 4 randomly selected 'user records' from the database -- say just the headshot photo or name from the database.
In addition to the recordset being randomly generated (i.e. our of about 50 records, only records 4, 18, 23 and 26 are displayed) I need to MAKE SURE they are not duplicated (i.e. out of the 50 records, records 4, 18, 23 and 23 -- where the last two are duplicates).
Is there a way I can pull this off and how do I go about it exactly?
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.
