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)) | +-------------------------------------+
Or, visually:
