ST_CurvePolygon(LONG VARCHAR[, INT]) constructor

Syntax

NEW ST_CurvePolygon(LONG VARCHAR text_representation[, INT srid])

text_representation – A string containing the text representation of a curve polygon. The input can be in any supported text input format, including Well Known Text (WKT) or Extended Well Known Text (EWKT).
srid – The SRID of the result. If not specified, the default is 0.

ST_CurvePolygon Returns an ST_CurvePolygon value constructed from the source string.

Example 1 – 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
```
