| |
| Introduction: Construct a Point from X, Y, Z, M and an optional srid. If srid is not set, it defaults to 0 (unknown). |
| Must use ST_AsEWKT function to print the Z and M coordinates. |
| |
| Format: |
| |
| `ST_PointZM (X: Double, Y: Double, Z: Double, M: Double)` |
| |
| `ST_PointZM (X: Double, Y: Double, Z: Double, M: Double, srid: Integer)` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.6.1` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_AsEWKT(ST_PointZM(1.2345, 2.3456, 3.4567, 100)) |
| ``` |
| |
| Output: |
| |
| ``` |
| POINT ZM(1.2345 2.3456 3.4567, 100) |
