Format

SDO_GEOR.setBeginDateTime(
     georaster  IN OUT SDO_GEORASTER, 
     beginTime  TIMESTAMP WITH TIME ZONE);

Description

Sets the beginning date and time for raster data collection in the metadata for a GeoRaster object, or deletes the existing value if you specify a null beginTime parameter.

Parameters

georaster

GeoRaster object.

beginTime

Time specification.

Usage Notes

To see the current beginning date and time (if any) in the metadata for the GeoRaster object, use the SDO_GEOR.getBeginDateTime function.

An exception is raised if beginTime is later than the ending date and time specified in the metadata for the GeoRaster object (see the SDO_GEOR.setEndDateTime procedure).

The GeoRaster object is automatically validated after the operation completes.

Examples

The following example sets the beginning and ending dates and times for raster data collection in the metadata for a GeoRaster object. (It refers to a table named GEORASTER_TABLE, whose 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.setBeginDateTime(grobj, timestamp '2002-11-15 15:00:00');
  sdo_geor.setEndDateTime(grobj, timestamp '2002-11-15 15:00:10');
  UPDATE georaster_table SET georaster = grobj WHERE georid=4;
  COMMIT;
END;
