| # ST_Force2D |
| |
| Introduction: Forces the geometries into a "2-dimensional mode" so that all output representations will only have the X and Y coordinates. This function is an alias of [ST_Force_2D](ST_Force_2D.md). |
| |
|  |
| |
| Format: `ST_Force2D (A: Geometry)` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.8.0` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_Force2D(ST_GeomFromText('POLYGON((0 0 2,0 5 2,5 0 2,0 0 2),(1 1 2,3 1 2,1 3 2,1 1 2))')) |
| ``` |
| |
| Output: |
| |
| ``` |
| POLYGON((0 0,0 5,5 0,0 0),(1 1,3 1,1 3,1 1)) |
| ``` |
