Detailed Description

The SQL driver plugin is a simple plugin interface that makes it easy to create your own SQL driver plugins that can be loaded dynamically by Qt.

Writing a SQL plugin is achieved by subclassing this base class, reimplementing the pure virtual function create(), and exporting the class with the Q_PLUGIN_METADATA() macro. See the SQL plugins that come with Qt for example implementations (in the plugins/src/sqldrivers subdirectory of the source distribution).

The json file containing the metadata for the plugin contains a list of keys indicating the supported sql drivers

 { "Keys": [ "mysqldriver" ] }
