15.10 - ST_IsValid - Teradata Database

Tests if an ST_Geometry value is well formed.

Returns an INTEGER value:

1, if the geometry is valid

0, if the geometry is not valid

All ST_Geometry types.

Note: This method can be called on 3D geometries (those that include z coordinates). However, the z coordinate is ignored in method calculations.

   WHERE shape.ST_IsValid() = 0

   ORDER BY skey;
