This package enables you to use Oracle Locator and the Spatial Option within Application Express. In an Application Express context, the logon user of the database session is typically APEX_PUBLIC_USER or ANONYMOUS. Spatial developers can not directly use DML on USER_SDO_GEOM_METADATA within such a session, for example, in SQL Commands within SQL Workshop. The Spatial view's trigger performs DML as the logon user, but it has to run as the application owner or workspace user. With the APEX_SPATIAL API, developers can use the procedures and functions below to insert, update and delete rows of USER_SDO_GEOM_METADATA as the current Application Express user. The package also provides a few utilities that simplify the use of Spatial in Application Express.
