Syntax
GEOMETRY ST_GeometryFromWKB(VARCHAR WKB)
Description
Converting a standard WKB (Well-known binary) into a corresponding memory geometry
example
mysql> select ST_AsText(ST_GeometryFromWKB(ST_AsBinary(ST_Point(24.7, 56.7))));
+------------------------------------------------------------------+
| st_astext(st_geometryfromwkb(st_asbinary(st_point(24.7, 56.7)))) |
+------------------------------------------------------------------+
| POINT (24.7 56.7) |
+------------------------------------------------------------------+
1 row in set (0.05 sec)
mysql> select ST_AsText(ST_GeomFromWKB(ST_AsBinary(ST_Point(24.7, 56.7))));
+--------------------------------------------------------------+
| st_astext(st_geomfromwkb(st_asbinary(st_point(24.7, 56.7)))) |
+--------------------------------------------------------------+
| POINT (24.7 56.7) |
+--------------------------------------------------------------+
1 row in set (0.03 sec)
mysql> select ST_AsText(ST_GeometryFromWKB(ST_AsBinary(ST_GeometryFromText("LINESTRING (1 1, 2 2)"))));
+------------------------------------------------------------------------------------------+
| st_astext(st_geometryfromwkb(st_asbinary(st_geometryfromtext('LINESTRING (1 1, 2 2)')))) |
+------------------------------------------------------------------------------------------+
