| # 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)` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.4.0` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_AsEWKT(ST_PointZ(1.2345, 2.3456, 3.4567)) |
| ``` |
| |
| Output: |
| |
| ``` |
| POINT Z(1.2345 2.3456 3.4567) |
| ``` |
