Remarks

The database table must contain two columns with X and Y coordinates of points (data type is Double). For example, the points may be stored as longitude/latitude coordinates.

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 FullExtent property.
