These functions are available for creating geometries from WKT values: ST_GeomCollFromText(wkt[, srid [, options]]), ST_GeometryCollectionFromText(wkt[, srid [, options]]), ST_GeomCollFromTxt(wkt[, srid [, options]]) Constructs a GeometryCollection ... These functions take as arguments a Well-Known Text (WKT) representation and, optionally, a spatial reference system identifier ...

MySQL provides several MySQL-specific functions that test the relationship between minimum bounding rectangles (MBRs) of two geometries g1 and g2. If any argument is geometrically invalid, either the result is true or false (it is undefined which), ...The return values 1 and 0 indicate true and false, ...
