I'm implementing paging through search results using cursors. Is there a
better way to know total number of rows under a cursor than running a
separate COUNT(*) query? I think PostgreSQL is bound to know this number
after the first FETCH, isn't it?
On a side note, why queries using LIMIT are SO terribly slow, compared to
cursors and sometimes even ones without LIMIT? Shouldn't LIMIT be internally
implemented using cursor mechanism then?...

I've got a form button that fires off 3 queries but if the first query
returns an error, I don't want the other two queries to happen.
Example: first query runs an insert from a linked table but if for some
reason a field is missing a value that's required, Access throws up an
error. At that point I just want to end the process and notify them of the
error so they can correct the data and try the process again.
Here's my code:

I just spent about 2 hours pulling my hair out over this issue, and I
don't want it to happen to anyone else ever again. Ever.
Basically you try to close a form using "DoCmd.Close", the form has a
parameter query somewhere on it (for me it was in a couple of combo
boxes), and you _sometimes_ get a dialog box asking you for the
parameter. If you've worked with parameter queries before you know the
box I'm talking about.
Here's the MS...

How do you get an accurate count of the number of records returned from
a query when using linked tables.
I have an access 2003 database as a front end to another access 2003
database that contains only tables. I have linked the tables for the
front end to the back end database.
I am trying to set the recordsource of a form to a query established by
the user to narrow the scope but I don't want to display the form if
there are no...

I've got a form - "frmLookup" (with a subform) that works very happily
on its own. The form has a list box, which when updated requeries the
subform to display the appropriate results.
The problem is that for the final user interface, I had planned to use
a "frmDisplay" form which had a number of menu items and then depending
on what the user selected, it would display the appropraite form in a
subform beneath the menu items. I did this...

Hi -
I'm trying to run a query as part of a VBA procedure, and what I want
it to do is to grab the value for a parameter (the current month) from
another part of the procedure. I clearly am missing something,
however. Here's what I have:
Dim db As Database
Dim rs As Recordset
Dim rs2 As Recordset

When automating e-mail messages from Access 2003 using DoCmd.SendObject, I get an Outlook warning message "A program is trying to automatically send e-mail on your behalf. Do you want to allow this?". Outlook then waits for a response. Since I want the message to be sent out from an unattended applicaton when certain conditions are met, is there a way to supress or bypass this message?

My clients have asked me to maintain a database that was developed in-
house. It's pretty good, considering the developer isn't a
"programmer".
The first thing they want me to do is to split it into a Front End/
Back End, which is very sensible. However, there are a number of ad
hoc queries that are required to be available to all users, which can
be edited, deleted or created "on the fly". The most sensible
solution would seem to be...
