revNumberOfRecords ruturns -1 in ODBC

[dave at b-i-s.org]

Hi,

I've just started using Revolution for a project. I'm using the revNumberOfRecords( 
RecordSetID) function but this only returns -1 with an ODBC data source. It's ok with 
MySQL. Am I stuck with this behavior or is there something I'm missing?

Thanks for any tips.
