14 -- NAME:
15 -- populate_index - tesselate all geometric objects in a geometry table
16 -- DESCRIPTION:
17 -- This procedure creates a maximum number of tiles to cover every geometric
18 -- object in the geometry table (LAYER_sdogeom). If the synch_flag is
19 -- TRUE only the geometric objects which do not already have corresponding
20 -- entries in the spatial index table (LAYER_sdoindex) are processed.
21 -- NOTES:
22 -- The behaviour of the POPULATE_INDEX( layer IN VARCHAR2 ) function is
23 -- determined by the values for the SDO_LEVEL and SDO_NUMTILES columns
24 -- in the <layer>_SDOLAYER table. The behaviour is described in the
25 -- following table:
26 --
27 -- VALUE OF SDO_LEVEL VALUE OF SDO_NUMTILES BEHAVIOUR
28 -- ------------------ --------------------- ------------------------
29 -- NULL NULL Error (use 7.3.3)
30 -- NULL NOT NULL Variable Tessellation
31 -- NOT NULL NULL Fixed Tessellation
32 -- NOT NULL NOT NULL Hybrid Tessellation
33 -- ARGUMENTS:
34 -- layer - geometry table name (LAYER_sdogeom) and spatial
35 -- index table name (LAYER_sdoindex) input argument
36 -- gid - Geometry IDentifier input argument
37 -- maxtiles - MAXimum number of TILES to generate input argument
38 -- synch_flag - tesselate only geometric objects having no corresponding
39 -- entries in the spatial index table if TRUE
40 -- (default value is TRUE)

57 -- DESCRIPTION:
58 -- This procedure creates a maximum number of tiles to cover a geometric
59 -- object in the geometry table (LAYER_sdogeom). If the replace_flag is
60 -- TRUE then any existing tiles for the specified object are first
61 -- removed from the index table (LAYER_sdoindex).

111 -- NOT NULL NOT NULL Call POPULATE_INDEX(). _SDOINDEX
112 -- table must be empty.
113 -- ARGUMENTS:
114 -- layer - name of LAYER to modify
115 -- sdo_level - new value for SDO_LEVEL column

125 --
126 -- This routine is ONLY for creating fixed tiles for point data.

133 -- The <layer>_sdogeom table must contain the SDO_CODE column.
134 -- The <layer>_sdogeom table can optionally contain the SDO_TILE column.
135 --
136 -- Parameters:
137 -- layer - The layer to tile
138 -- sdo_tile_flag - If TRUE, will generate the sdo_tile column.
139 -- Default is FALSE.
140 -- commit_cnt - Routine updates in increments of commit_cnt,
141 -- and commits each increment.
