ST_CurvePolygon(LONG VARCHAR[, INT]) constructor

NEW ST_CurvePolygon(text-representation[, srid])

Name	Type	Description
text-representation	LONG VARCHAR	A string containing the text representation of a curve polygon. The input can be in any supported text input format, including WKT or EWKT.
srid	INT	The SRID of the result. If not specified, the default is 0.

Constructs a curve polygon from a character string representation. The database server determines the input format by inspecting the provided string.

The following returns CurvePolygon (CompoundCurve (CircularString (-5 -5, 0 -5, 5 -5), (5 -5, 0 5, -5 -5)))

SELECT NEW ST_CurvePolygon('CurvePolygon (CompoundCurve (CircularString (-5 -5, 0 -5, 5 -5), (5 -5, 0 5, -5 -5)))')

The following example shows a curvepolygon with a circle as an outer ring and a triangle inner ring.

SELECT NEW ST_CurvePolygon('CurvePolygon ( CircularString (2 0, 5 3, 2 0), (3 1, 4 2, 5 1, 3 1)  )') cpoly
