Public Class MySqlLayer
    Inherits SpatialDatabaseLayer
C#

Remarks

This class supports the MySql GEOMETRY data type and spatial indexes.

The FieldList property should be specified if attribute data from the database is necessary property should be specified if attribute data from the database is necessary (for labeling, quering, or editing purposes).

The extent of database layers is not calculated automatically for performance reasons. If you use only database layers in your application, you should set the Extent property before adding the layer to the map.

By default, the extent of database layers is set to (-180,90,180,-90) (units are decimal degrees). The coordinate system is set to WGS 1984 (EPSG/SRID code is 4326).
