<DL> <DT><SPAN class=term>ST_NumInteriorRings(geometry)</SPAN> <DD> <DIV>
Return the number of interior rings of the first polygon in the geometry.
Return NULL if there is no polygon in the geometry.</DIV> <DT><SPAN
class=term>ST_NumInteriorRing(geometry)</SPAN> <DD> <DIV>Synonym to
NumInteriorRings(geometry). The OpenGIS specs are ambiguous about the exact
function naming, so we provide both spellings.</DIV> <DT><SPAN class=term>
ST_InteriorRingN(geometry,integer)</SPAN> <DD> <DIV>Return the N'th interior
ring of the polygon geometry. Return NULL if the geometry is not a polygon
or the given N is out of range.</DIV> <DT><BR></DT></DL>Fred.<BR><BR><BR>
