As I recall, some ODBC drivers simply don't support a numRows call -- and
they return -1 when they get used...
At a minimum, if you want a good answer, you really need to tell the list
*WHICH* odbc driver you are using, as well as *which* object-oriented
database abstraction layer you are using in your $db variable.
And, finally, what kind of database you are connecting to -- ODBC works
with virtually every database on the planet. Some databases won't support
a numRows() function, or at least not in some circumstances.
Of course, it's also possible that your db abstraction layer in $db
doesn't return an integer of the number of rows from numRows() method, but
returns some kind of object instead, and you need to call a method on that
object to find out the actual number of rows. That would be a pretty
goofy thing to do, but it's possible.
As it stands now, we have nowhere near enough info to help you!
You should also try using var_dump() and printr() on your $numRecords
object to see what structure it has. That alone could tell you what is
going on.
