Format

SDO_GEOR.getBeginDateTime(
     georaster  IN SDO_GEORASTER 
     ) RETURN TIMESTAMP WITH TIME ZONE;

Description

Returns the beginning date and time for raster data collection in the metadata for a GeoRaster object.

Parameters

georaster

GeoRaster object.

Usage Notes

To set the beginning date and time for raster data collection in the metadata for a GeoRaster object, use the SDO_GEOR.setBeginDateTime procedure.

If georaster or its metadata is null, this function returns a null value.

Examples

The following example returns the beginning and ending dates and times for raster data collection in the metadata for the GeoRaster object in a table named GEORASTER_TABLE where the GEORID column contains the value 4. (The GEORASTER_TABLE table definition is presented after Example 1-1 in Storage Parameters.)

SELECT sdo_geor.getBeginDateTime(georaster) beginDateTime,
  sdo_geor.getEndDateTime(georaster) endDateTime
  FROM georaster_table WHERE georid=4;
