ST_CurveN method

Returns the nth curve in the compound curve.

By default, ST_CurveN uses the original format for a geometry, if it is available. Otherwise, the internal format is used. For more information about internal and original formats, see STORAGE FORMAT clause, CREATE SPATIAL REFERENCE SYSTEM statement.

compoundcurve-expression.ST_CurveN(n)

Name	Type	Description
n	INT	The position of the element to return, from 1 to compoundcurve-expression.ST_NumCurves().

ST_Curve Returns the nth curve in the compound curve.
The spatial reference system identifier of the result is the same as the spatial reference system of the compoundcurve-expression.
