Creating indexes for performance

To achieve performance you must create indexes, depending on your spatial extension.

Universal

Here is a proposal if you have more tiles in the x direction than in the y direction. If the opposite is true, switch Minx / Miny and Maxx/ Maxy:

CREATE INDEX IX_SPATIAL0_1 ON SPATIAL0(MinX,MinY)
CREATE INDEX IX_SPATIAL0_2 ON SPATIAL0(MaxX,MaxY)

DB2 Spatial Extender

Use gseidx utility (ADVISE) to get a proposal for the last 3 parameters (grid sizes):

CREATE INDEX IX_SPATIAL0 ON SPATIAL0(GEOM) EXTEND USING db2gse.spatial_index (10000.0, 100000.0, 1000000.0)

PostGIS

Use:

CREATE INDEX IX_spatial0 ON spatial0 USING gist(geom)

MySQL

Use:

CREATE SPATIAL INDEX IX_SPATIAL0 ON SPATIAL0(GEOM)

Oracle Location Based Services

Use:

CREATE INDEX IX_SPATIAL0 ON SPATIAL0(GEOM) INDEXTYPE IS MDSYS.SPATIAL_INDEX
