•For functions that take multiple geometry arguments, if those arguments are not in the same SRS, an ER_GIS_DIFFERENT_SRIDS  error occurs. 

•If any argument is geometrically invalid, either the result is true or false (it is undefined which), or an error occurs. 

•For geographic SRS geometry arguments, if any argument has a longitude or latitude that is out of range, an error occurs: 

• If a longitude value is not in the range ( − 180, 180], an ER_GEOMETRY_PARAM_LONGITUDE_OUT_OF_RANGE  error occurs ( ER_LONGITUDE_OUT_OF_RANGE prior to MySQL 8.0.12). 

• If a latitude value is not in the range [ − 90, 90], an ER_GEOMETRY_PARAM_LATITUDE_OUT_OF_RANGE error occurs ( ER_LATITUDE_OUT_OF_RANGE  prior to MySQL 8.0.12). 

Ranges shown are in degrees. If an SRS uses another unit, the range uses the corresponding values in its unit. The exact range limits deviate slightly due to floating-point arithmetic. 

•Otherwise, the return value is non- NULL . 

These MBR functions are available for testing geometry relationships: 

• MBRContains( g1 , g2 ) 

Returns 1 or 0 to indicate whether the minimum bounding rectangle of g1  contains the minimum bounding rectangle of g2 . This tests the opposite relationship as MBRWithin() . 

MBRContains()  handles its arguments as described in the introduction to this section. 

mysql> SET @g1 = ST_GeomFromText(’Polygon((0 0,0 3,3 3,3 0,0 0))’); mysql> SET @g2 = ST_GeomFromText(’Point(1 1)’); mysql> SELECT MBRContains(@g1,@g2), MBRWithin(@g2,@g1);

• MBRCoveredBy( g1 , g2 ) 

Returns 1 or 0 to indicate whether the minimum bounding rectangle of g1  is covered by the minimum bounding rectangle of g2 . This tests the opposite relationship as MBRCovers() . 

MBRCoveredBy()  handles its arguments as described in the introduction to this section. 

mysql> SET @g1 = ST_GeomFromText(’Polygon((0 0,0 3,3 3,3 0,0 0))’); mysql> SET @g2 = ST_GeomFromText(’Point(1 1)’); mysql> SELECT MBRCovers(@g1,@g2), MBRCoveredby(@g1,@g2);
