ST_Intersection

Applies to ❌ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

This function intersects two geometries. For example:

create.select(stIntersection(
  stGeomFromText("POLYGON ((-1 -1, 1 -1, 1 1, -1 1, -1 -1))"),
  stGeomFromText("POLYGON ((0 0, 2 0, 2 2, 0 2, 0 0))"),
)).fetch();

The result being, for example

+-------------------------------------+
| ST_Difference                       |
+-------------------------------------+
| POLYGON ((1 1, 1 0, 0 0, 0 1, 1 1)) |
+-------------------------------------+
