CREATE INDEX
To determine if a CREATE INDEX statement for a spatial index has failed, check to see
if the DOMIDX_OPSTATUS column in the USER_INDEXES view is set to FAILED.
This is different from the case of regular indexes, where you check to see if the STATUS
column in the USER_INDEXES view is set to FAILED.
If the CREATE INDEX statement fails because of an invalid geometry, the ROWID of
the failed geometry is returned in an error message along with the reason for the
failure.
If the CREATE INDEX statement fails for any reason, then the DROP INDEX statement
must be used to clean up the partially built index and associated metadata. If DROP
INDEX does not work, add the FORCE parameter and try again.
The following example creates a spatial R-tree index named COLA_SPATIAL_IDX.
CREATE INDEX cola_spatial_idx ON cola_markets(shape)
INDEXTYPE IS MDSYS.SPATIAL_INDEX;
