MySQL 5.6 Reference Manual  /  ...  /  Spatial Relation Functions That Use Minimum Bounding Rectangles (MBRs)

12.15.9.2 Spatial Relation Functions That Use Minimum Bounding Rectangles (MBRs)

The OpenGIS specification defines the following functions that test the relationship between two geometry values g1 and g2. The MySQL implementation uses minimum bounding rectangles, so these functions return the same result as the corresponding MBR-based functions. The return values 1 and 0 indicate true and false, respectively.
