We are trying to migrate our Informix Spatial datablade specific queries
onto Oracle Spatial.
The queries are using informix blade's inbuilt functions like
SE_NEAREST, SE_POLYFROMSHAPE.
Where can we find the equivalent Oracle functions for these.

Hi,

SE_NEAREST - Use the SDO_NN (Return Nearest Neighbors) or SDO_WITHIN_DISTANCE operators.

SE_POLYFROMSHAPE - not sure, try SDO_MBR (minimum bounding rectangle around a geometry object) or SDO_CONVEXHULL (convex polygon around the input geometry).

For more info, see the Oracle Spatial User's Guide and Reference.

Best regards.

Frank
