Hi All,

I have a component written in c++ and using the OCI api. It is a middle tier component that does the Spatial data manipulation, but it has quite a few problems.

Is it possible to convert this component to use only sql instead of the OCI api? IE: Is there a way to use the spatial functions in a language independant way?

Regards,
Pieter

Yes. You may refer to Oracle Spatial User's Guide and Reference for more information.

e.g. the following SQL statement

SQL> SELECT count(*)
FROM XYplot_all_wgs84 a, ClimateZone_WGS84 B
WHERE B.objectid = 6
AND SDO_RELATE(A.Shape, B.Shape,
'mask=inside querytype=WINDOW') = 'TRUE';

will return the number of matched rows of A (point) inside B (polygon), where a.shape and b.shape must be stored in the type of MDSYS.SDO_GEOMETRY.

Good luck.
