ST_Within
Applies to ❌ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
This predicate checks if one geometry is within another. This is the inverse of ST_Contains. For example:
create.select(
field(stWithin(
stGeomFromText("POINT (-2 0)"),
stGeomFromText("POLYGON ((-3 -1, -1 -1, -1 1, -3 1, -3 -1))")
)),
field(stWithin(
stGeomFromText("POINT (4 0)"),
stGeomFromText("POLYGON ((3 -1, 1 -1, 1 1, 3 1, 3 -1))")
))
).fetch();
The result being, for example
+-----------+-----------+ | ST_Within | ST_Within | +-----------+-----------+ | true | false | +-----------+-----------+
