7.44 SDO_GEOR.getBlockingType
Format
SDO_GEOR.getBlockingType( georaster IN SDO_GEORASTER ) RETURN VARCHAR2;
Description
Returns the blocking type for a GeoRaster object.
Usage Notes
This function returns one of the following values: NONE
or REGULAR
:
-
NONE
means that the GeoRaster object is not blocked, but is a single BLOB object. -
REGULAR
means that the GeoRaster object uses regular blocking, that is, each block has the same dimension sizes.
If georaster
or its metadata is null, this function returns a null value.
Examples
The following example returns the cell depth, interleaving type, and blocking type of the GeoRaster object (GEORASTER column) in the row with the GEORID column value of 21 in the GEORASTER_TABLE table, whose definition is presented after Example 1-1 in Storage Parameters.
SELECT sdo_geor.getCellDepth(georaster) CellDepth, substr(sdo_geor.getInterleavingType(georaster),1,8) interleavingType, substr(sdo_geor.getBlockingType(georaster),1,8) blocking FROM georaster_table WHERE georid=21; CELLDEPTH INTERLEA BLOCKING ---------- -------- -------- 8 BSQ REGULAR
