ST_PointZ

Introduction: Construct a Point from X, Y and Z and an optional srid. If srid is not set, it defaults to 0 (unknown). Must use ST_AsEWKT function to print the Z coordinate.

Format:

ST_PointZ (X: Double, Y: Double, Z: Double)

ST_PointZ (X: Double, Y: Double, Z: Double, srid: Integer)

Since: v1.5.0

Example:

SELECT ST_AsEWKT(ST_PointZ(1.2345, 2.3456, 3.4567))

Output:

POINT Z(1.2345 2.3456 3.4567)
