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?
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 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.
(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:
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:
<% 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 have a database with 3 tables in it.(Imagine as there are 3 levels, one level for each table)
on level 1, there are 3 entries:A,B,C
on level 2, the entries are tied to one of the entries in level 1, ie those in level 2 will be A.1, A.2, A.3, B.1,B.2,C.1,C.2.....
on level 3, the entries are tied to one of the entries in level 2, ie those in level 3 will be A.1.1, A.1.2, A.1.3, A.2.1,A.2.2,B.1.2,C.2.1.....
I have 3 combo boxes on my webpage. I want it to be able to do the following:
when i make my choice on combobox 1 which holds the information of level 1, only those entries corresponding to the choice made in combobox1. ie if in combobox 1, i chose A, then i only wan those of A.1,A.2,A.3 to be shown in combobox 2.... after which, say I choose A.1 in combobox 2, I only wan those of A.1.1, A.1.2,A.1.3 to be shown in combobox 3.
Is this achievable in asp and sql since it sort of requires dynamic programming?
I have a service which provides video clips with a subscription service, and I have a few big corporations using it. These big corporations all use the same login and password for their company, but the users requesting the passwords will all have different emails, but the part after the @ will be the same. I.E mruser@microsoft.com.I need a script that will only check that part of their email, and based on which one it matches it will send them the correct password for their company.
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.
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 an insert record form that posts fine to a db which automatically creates an ID how could I get the next page to do a preview using the ID just created by the DB to go to the right record?
I have a .asp page which lists a date, then a bunch of record lines for data that falls within that date, then the next date and it's bunch of data record lines. e.g.
Ship Date: 04/06/04
Data xxxxxxxxxxxxxxxxxxxxx Data xxxxxxxxxxxxxxxxxxxxx Data xxxxxxxxxxxxxxxxxxxxx Data xxxxxxxxxxxxxxxxxxxxx
Ship Date: 11/07/04
Data xxxxxxxxxxxxxxxxxxxxx Data xxxxxxxxxxxxxxxxxxxxx Data xxxxxxxxxxxxxxxxxxxxx
What I want is:
Ship Date: 04/06/04
1: Data xxxxxxxxxxxxxxxxxxxxx 2: Data xxxxxxxxxxxxxxxxxxxxx 3: Data xxxxxxxxxxxxxxxxxxxxx 4: Data xxxxxxxxxxxxxxxxxxxxx
Ship Date: 11/07/04
1: Data xxxxxxxxxxxxxxxxxxxxx 2: Data xxxxxxxxxxxxxxxxxxxxx 3: Data xxxxxxxxxxxxxxxxxxxxx
How can I get these numbers printed againsts the records ?
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 done random image display with the help suggestion from this discussion form. now I want to provide link on each image. i.e. all the images display randomly, should have different link. is it possible? if yes, how?
is there sombody who can helpme witht he following, i am ''pretty new'' to php and am looking for a script to show images randomly at a 10/ 15 seconds interval. is there anybody who can help me with this or does know where to find a good template script for this?
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 %>
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
I have a file where i want to call a random asp file using the "include file" statement. I know it can be done with images, but can it be done with other asp files? and how?
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 set up a random code for people registering with my site.....
letters="1234567890abcdefghijklmnopqrstuvwxyz" for i=1 to 16 Randomize() rNum=Int(Rnd()*36)+1 code=code&mid(letters,rNum,1) next
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.
trying to get a random number from 0000 to 9999, is there an easy way to do this? i'm using this for a unique filename and want it to be 4 digits from 0000 to 9999.
i have a db where ± 15 users stores multiple second hand items with images. Now i wish to display on the openingpage a list of all users with 1 item + image. So far no problem.
But now i wish to change the order of the users every time the pages open.
How can i shuffle the recordset before i load the users in a array, or how can i shuffle the array after populating with the users? Code:
