Format

SDO_GEOR.setSpatialReferenced(
     georaster     IN OUT SDO_GEORASTER, 
     isReferenced  IN VARCHAR2);

Description

Specifies whether or not a GeoRaster object is spatially referenced, or deletes the existing value if you specify a null isReferenced parameter.

Parameters

georaster

GeoRaster object.

isReferenced

Specify TRUE to specify that the GeoRaster object is spatially referenced, FALSE to specify that the GeoRaster object is not spatially referenced, or null if the GeoRaster metadata does not contain spatial reference information. Must be TRUE or FALSE (case-insensitive) if the GeoRaster metadata contains spatial reference information.

Usage Notes

This procedure sets the GeoRaster object to be spatially referenced or not spatially referenced.

The GeoRaster object is automatically validated after the operation completes.

Examples

The following example sets the GeoRaster object (GEORASTER column) in the row with the GEORID column value of 4 in the GEORASTER_TABLE table as not spatially referenced. (The GEORASTER_TABLE table definition is presented after Example 1-1 in Storage Parameters.)

DECLARE
  grobj sdo_georaster;
BEGIN
  SELECT georaster INTO grobj FROM georaster_table WHERE georid=4 FOR UPDATE;
  sdo_geor.setSpatialReferenced(grobj, 'FALSE');
  UPDATE georaster_table SET georaster = grobj WHERE georid=4;
  COMMIT;
END;
