download_cursor   At each remote database, the SalesRep table contains a single row. There is very little overhead for the download of a single row, so a simple snapshot download_cursor script is used:

SELECT rep_id, name FROM SalesRep WHERE ? IS NOT NULL AND ml_username = ?

The first parameter in the script is the last download timestamp, which is not used. The IS NOT NULL expression is a dummy expression supplied to use the parameter. The second parameter is the MobiLink user name.
