Re: Query directly from secondary index

Steven,

My app handles this already.  In this routine, all I need is a table
containing
the 'Key' values.  If there is more than one row, I show the user a screen
asking them to choose.  Its DM has the Answer.db linked 1-1 to Customer.db
(to show other descriptive fields).

>and, FWIW, you're still doing a dot-dot query, 
>that has to go thru all records..

Exactly my point.  By directly querying the Customer.XG1 file, I avoid
querying
Customer.DB.  Since the XG1 only has 2 columns, it should be much faster
than going after my 'wide' tables.

Thanks,
Jim Moseley
