VBA DAO Query Result Set

Posted on 2011-09-11

Last Modified: 2012-05-12

I am trying to create a VB script to automate a mailing based on several query result sets from access. I have gotten to the stage that the output is correct but have a problem with the 5th and 6th record set query as they only return one record (When in fact there should be at least two for each).

I don't really understand why this is happeneing as the SQL is exactly the same as in the 2nd record set - which works perfectly. Also I've tested the SQL directly in an access query & there are no errors in the formatting that I can see... correct number of records returned.

I'd appreciate any help you could offer.

<as they only return one record (When in fact there should be at least two for each).>

Are you basing this ("one record") on the RecordCount property?

This is inaccurate, because the RecordCount property is always 1 or zero when the recordset is initially opened.  It is zero if there are no records; 1 if there are records.  It will display the correct "total records" if you use a moveLast statement.

In general, don't use RecordCount to determine the endpoint of your recordset loops.  Do something like this instead:

Do Until objRS6.EOF
     If ccaddress = "" Then ccaddress = objRS6.Fields("Email_Address") Else ccaddress = ccaddress & "; " & objRS6.Fields("Email_Address")

This applies to any recordset loop you are currently using RecordCount as criteria for ending.

If a table is local (as opposed to Linked) ... and you need the RecordCount, that fastest, most efficient way is:

Dim lCnt As Long
lCnt = CurrentDB.TableDefs("YourTableName").RecordCount

@ DatabaseMX thanks for the tip i'll give it a go.

@ mbizup thanks for your advice - this makes sense and is more than likely the issue. However switching  to the code you suggest has resulted in a "loop without a do" error ... Although there is a Do for Each loop. Quick google shows that the error is usually because of open If /Else statements. So I commented them all out & still no luck ...

Is there a limit to the number of nested loops you can have within a loop?

Ignore that - I commented a Next out by mistake. Resolved - Thanks for your help!

I think mbizup meant this:

Do Until objRS6.EOF
    If ccaddress = "" Then
             ccaddress = objRS6.Fields("Email_Address")
             ccaddress = ccaddress & "; " & objRS6.Fields("Email_Address")
   End If

Glad that worked out.

<I think mbizup meant this...>

That was actually a direct copy/paste from bedsingar's code, and should work as-is.  Since it was written as a single line of code instead of as a block, the End If is not needed.
