Remarks

This enumeration provides the available operations that can be used when accessing the database table. They reflect the basic operations when accessing an ISAM file. These enable Symphony.dB to replicate these ISAM operations onto the chosen database.

These methods are designed to be used by the Symphony.dB.SQLDispatcher class and not from user code.
