Abstract action for common function needed by database actions. The difference to the other Database*Actions is, that the actions in this package use additional components ("modules") for reading and writing parameters. In addition the descriptor format has changed to accomodate the new features.

This action is heavily based upon the original DatabaseAddActions.

Modes have to be configured in cocoon.xconf. Mode names from descriptor.xml file are looked up in the component service. Default mode names can only be set during action setup.

The number of affected rows is returned to the sitemap with the "row-count" parameter if at least one row was affected.

All known column types can be found in JDBCTypeConversions .

Configuration options (setup):
input	default mode name for reading values (request-param)
autoincrement	default mode name for obtaining values from autoincrement columns (auto)

first-row	row index of first row (0)
