Spatial query w/o spatial data

Question

I trying to execute a next query on Oracle Database 11g Enterprise Edition (11.1.0.6.0):

SELECT "__ItemId"
FROM "Cities"
WHERE "Longitude" IS NOT NULL AND "Latitude" IS NOT NULL
  AND SDO_ANYINTERACT(SDO_GEOMETRY('POINT(' || "Longitude" || ' ' || "Latitude" || ')'),
    SDO_UTIL.FROM_WKTGEOMETRY('POLYGON ((-100 80, 100 80, 100 -80, -100 -80, -100 80))')) = 'TRUE'

Where "Longitude" and "Latitude" - numeric [NUMBER(28,5)] columns in the "Cities" table.

UPD: Next query (with the same error) can be used for tests:

SELECT 'Solved!'
FROM DUAL
WHERE SDO_ANYINTERACT(SDO_GEOMETRY('POINT(' || 100 || ' ' || 100 || ')'),
  SDO_UTIL.FROM_WKTGEOMETRY('POLYGON ((-150.0 82.0, 150.0 82.0, 150.0 -67.0, -150.0 -67.0, -150.0 82.0))')) = 'TRUE';

I get an error:

Error report -
SQL Error: ORA-13226: interface not supported without a spatial index
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 8
ORA-06512: at "MDSYS.SDO_3GL", line 71
ORA-06512: at "MDSYS.SDO_3GL", line 239
13226. 00000 -  "interface not supported without a spatial index"
  *Cause:    The geometry table does not have a spatial index.
  *Action:   Verify that the geometry table referenced in the spatial operator
             has a spatial index on it.

Questions:

1. How can I check, that point with specified "Longitude" and "Latitude" in the specified polygon? Polygon in not always simple, it can be any.
2. How can I create a spatial index on a table without any spatial column?
3. It's really, I can not just call a spatial operator?

Answer 1

As the error messages state, you need a Spatially indexed column to make use of the Spatial operators.

You can get equivalent functionality from the RELATE function in the SDO_GEOM package using the mask "ANYINTERACT":

SELECT sdo_geom.relate(a, 'ANYINTERACT', b, 0.05)
FROM dual
