21 Spatial Aggregate Functions
This chapter contains reference and usage information for the spatial aggregate functions.
See the usage information about spatial aggregate functions in Spatial Aggregate Functions.
Most of these aggregate functions accept a parameter of type SDOAGGRTYPE, which is described in SDOAGGRTYPE Object Type.
Note:
Spatial aggregate functions are supported for two-dimensional geometries only, except for SDO_AGGR_MBR, which is supported for both two-dimensional and three-dimensional geometries.
