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.
MBRContains() and
Contains() are synonyms. For
more information, see the description of
MBRContains().
MBRDisjoint() and
Disjoint() are synonyms. For
more information, see the description of
MBRDisjoint().
Returns 1 or 0 to indicate whether
g1 is spatially equal to
g2.
MBRIntersects() and
Intersects() are synonyms.
For more information, see the description of
MBRIntersects().
MBROverlaps() and
Overlaps() are synonyms. For
more information, see the description of
MBROverlaps().
MBRWithin() and
Within() are synonyms. For
