Hi Tobias and Ruben,
Having the row number is not enough if you don't know which rows you
need :-)
Actually, a complete query mechanism is not (yet?) implemented in
OpenMap.
However, you can extend EsriPlugin to perform JDBC/SQL queries on the
DBF tables using an appropriate JDBC driver.
Unfortunately, unless you only work with Windows, for which you can use
the free jdbc/odbc bridge, there is no free jdbc driver available. I
think the most easy to use solution can be found on
http://www.hxtt.net/
You also can extend the esri layer/plugin to use full fledge sql
engines, but this requires the tables to be imported in the database. A
"lighter" solution is to use hsqldb (hsqldb.sf.net) which can create
"memory" databases on the fly... I think that Don has investigated this
particular approach.
Best regards,
Bart
