12.15.8 Functions That Test Spatial Relations Between Geometry Objects

12.15.8.1 Spatial Relation Functions That Use Object Shapes
12.15.8.2 Spatial Relation Functions That Use Minimum Bounding Rectangles (MBRs)
12.15.8.3 MySQL-Specific Spatial Relation Functions That Use Minimum Bounding Rectangles (MBRs)

The functions described in this section take two geometries as arguments and return a qualitative or quantitative relation between them.
