SDO_GEOR.getBandDimSize

Format

SDO_GEOR.getBandDimSize(
     georaster  IN SDO_GEORASTER
     ) RETURN NUMBER;

Description

Returns the number of bands in a GeoRaster object.

Parameters

georaster

GeoRaster object.

Usage Notes

For an explanation of bands, see Bands_ Layers_ and Metadata.

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

Examples

The following example returns the spatial dimension sizes and the number of bands (one in this case) for a GeoRaster object. (It refers to a table named GEORASTER_TABLE, whose definition is presented after Example: Using storageParam Keywords in Storage Parameters. The output is reformatted for readability.)

SELECT sdo_geor.getSpatialDimSizes(georaster) spatialDimSizes,
       sdo_geor.getBandDimSize(georaster) bandDimSize
  FROM georaster_table WHERE georid=21;
