Declare Recordsets on the fly VB6?

Hi, I'm trying to Declare and execute recordsets inside a loop.  I can't declare them all upfront because I don't know how many there might be.  Is it possible to pass a string as the name of a recordset?

I cleaned up the code to execute 10 times, but like I said, this isn't really the case.  The loop would execute a varying number of times.

Thanks
Dim intCounter As Integer
Dim strRS As String
Do Until intCounter = 10
 
    strRS = "rs" & intCounter
    
    Dim (strRS) As Recordset
    (strRS).Open strcon
   intcounter = intcounter + 1
Loop

Open in new window

If you have to keep all the recordsets open and hence cannot reuse the Recordset variable, you could declare an unsized array and ReDim it.

Dim intCounter As Integer
Dim RS () As Recordset

Do Until intCounter = 10
    redim preserve RS(intCounter)
   
    RS(intCounter).Open strcon
   intcounter = intcounter + 1
Loop

Not to get into the why, that you need that open recordsets, I personally can't remember ever having to have open more than 2. But anyway, remember you are going to have to keep track of all of them no matter how you do open them, to close each one of them.

Thanks both for your feedback.  You're right; I was making this way too complicated.  I just declared one recordset before starting the loop, kept the information in an array and then closed the recordset at each iteration of the loop.

also note that opening recordsets for each record (in a loop)  is not a good practise.
if possible, try to combine the sql so that you do not have to execute them in a loop. YOu should try to lessen the number of server requests.
maybe your first record set gets you a filtered list and inside the loop, you are getting additional value, setting value, etc.
you should attempt to combine the sql which gets you the list and what you want to do with time.
