| # ST_Distance |
| |
| Introduction: Returns the minimum geodesic distance between two geography objects in meters. Uses S2 geometry-to-geometry distance (S2ClosestEdgeQuery), which computes the true minimum distance between any two points on the geometries — not centroid-to-centroid. Consistent with sedona-db's implementation. |
| |
|  |
| |
| Format: |
| |
| `ST_Distance (A: Geography, B: Geography)` |
| |
| Return type: `Double` |
| |
| Since: `v1.9.1` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_Distance( |
| ST_GeogFromWKT('POINT (0 0)'), |
| ST_GeogFromWKT('POINT (1 1)') |
| ); |
| ``` |
| |
| Output: |
| |
| ``` |
| 157249.59847404022 |
| ``` |
| |
| The result is approximately 157 km, the great-circle distance between (0,0) and (1,1) on the WGS84 sphere. |
