Counting Records Returned From A Database
I've been trying to find a simple way to count the records returned from a database query short of looping through the recordset and incrementing a counter.
I've tried the following without any success:
Ubound(select_rs) - afterall the recordset is returned in an array right? Ubound gives the following error: Microsoft VBScript runtime (0x800A000D)
Type mismatch
I've tried select_rs.count which gives the following error: VBScript runtime (0x800A01B6)
Basically, I've reached the point where I think I may have to loop through the recordset and count the number of records returned. Seems like an awfully inefficent way to do something so simple.

Is there another way to count the records of an access database that have a specific field other than using a SELECT statement and a recordset to loop through the records?

On access, I used the simple recordcount property, but on mySQL, all the counts turn to -1...here's my code for one of them:
[VBS]
set Count = Server.CreateObject("ADODB.Recordset")
sqlSelect = "SELECT * FROM Articles WHERE Pending = 'No';"
Count.Open sqlSelect, Connect, adOpenStatic, adLockReadOnly
%>
We have <b><font color="red"><%=Minus(Count.RecordCount)%></font></b> articles!
<%Count.Close
set Count = Nothing
[/vbs]

I have fields called EventName and EventVolunteer. What I want to do is do a count of volunteers for each event. Then as it loops though the database the results display next to the Event Name.

short n simple question: I want to display the number of records returned from a search. Code fragment as follows:
// d/b retrieval SQL code
SQLCode = SQLCode
Set objRS = objConn.Execute (SQLCode)
// displaying the returned results
Do While (Not objRS.EOF
<< spit out records >>
objRS.MoveNext
Loop
Now, is there an instance of objRS I can call that will just display how many records were returned? I tried objRS.Count on a longshot, but that didn't work

I have been using the following code to count the number of rows returned from a query:
Alldata = rs.Getrows()
NumRows = Ubound(Alldata, 2)
The problem is I am now having to limit the number of rows that it returns:
Alldata = rs.Getrows(300)
Now my NumRows always equals 300 no matter how many matches are found so my counter doesn't work. Does anyone know a way around this?I know that I can use SELECT COUNT(*)..... instead in an SQL query but that means making two trips to the server which I don't really want to do.

I have an access table which I filtered with the code below.
'''''''''## FILTER AND SORT MAIN TO SOFTWARE ##''''''''''
rsMain.Filter = "asset = ' " & rsSoft("assetnumber") & " '"
'''''''''## END FILTER AND SORT MAIN TO SOFTWARE ##''''''''''
My question is is there a command that will return the amount of records in rsMain without using loops (while Do ect)?

I have a query that is supposed to return only 1 record, however I recently found that because of an error in the database it can return more than 1. So what I need to do is capture if it is more than 1 record and alert the user to contact the database administrator. How can I get the count of records returned by a recordset? Is there no way besides looping through with a counter variable?

I've created a Stored Procedure which adds a new record and updates some more records and then returns the primary key for the added record.
The SP seems to work OK, but I'm having problems getting at the returned key in my ASP code:
"Item cannot be found in the collection corresponding to the requested name or ordinal."
A common error, but in this case I can't see why... I output the SQL instruction that is sent to the DB and have run it in Query Analyser and it runs OK and returns a single row, with a single column - the new primary key...
But when I try and access this in ASP, I get the error message....

I'm trying to pull the last 5 records from my database.
<% j=5
rs.MoveLast
While ((j>0) AND (NOT rs_article.BOF))%>
''Execute HTML and data insertion here
<%rs_article.MovePrevious
j=j-1
Wend%>
Everytime I attempt to run this code, I recieve an HTTP 500- Internal Server Error. It tells me no more than that. I know that my connection settings are OK because when I move forward through the database (first five records), the code executes without error. And yes, my Cursor type is Dynamic.
Alternatively, I would also like to know how to add new recordset to the beginning of a database rather than the end.

Does anyone know if it's possible to use the records stored in an Access 2002 database to log users into an ASP.net page? I'm trying to code it in vb.net but im not sure how it could be done. Basically I think I need 2 text boxes on the ASP page where the user can enter their name and password.
I then somehow need to retrieve the name and password from fields in the database (using ADO.net i think) and compare them with those entered by the user. If they match then I want to load another page, and if not then I want to display a message saying login details are incorrect.
Any help on this subject would be much appreciated- the fields i have at the moment are called 'User' and 'Password' in a table called PERSON.

I need to insert many records from one table of one db to another table in another db.
I have done this, but I have a problem in the case that if an IDNumber is unique in the destination table.
How can I, In the case that record (IDNumber) already exists, to skip that record and continue normally with the rest of records. Not to update that record but to skip that record.

I've got this bit of code that prints out the data from a database to a webpage. Some of the entries in the db are blank whereas others aren't. The code checks if its blank and moves to the next record. If it's not blank it lables it and prints the data stored in the db cell.
The prob that it won't print out the db info in the else statement. If I get rid of the if statement completly, it prints every cell including the blank ones. I'm drawing a blank on how to fix it. Could be because I've been looking at it too long.....

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?

I have a web application that simply has 2 text boxes with a start and end date. I have a submit button which triggers the delete from an access database. I use vb.net and asp.net with an access database.
I either don't display "record deleted" or always display "record deleted". I tried the textboxchanged, but that doesn't trigger until I hit the submit button. I tried response.redirect, response.write and even tried using a label with the message. Can anyone tell me how to stop the "recode deleted" upon clicking on the textbox or clicking anywhere on the form.
