ST_Equals

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

This predicate checks if a geometry is "spatially equal" to another geometry (i.e. the ordering of points is irrelevant for this equality). For example:

create.select(field(stEquals(
  stGeomFromText("LINESTRING (-1 -1, 1 1)"),
  stGeomFromText("LINESTRING (1 1, -1 -1)")
))).fetch();

The result being, for example

+-----------+
| ST_Equals |
+-----------+
| true      |
+-----------+
