| ## ST_GeometryFromWKB,ST_GeomFromWKB |
| |
| ### 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)')))) | |
| +------------------------------------------------------------------------------------------+ |
| | LINESTRING (1 1, 2 2) | |
| +------------------------------------------------------------------------------------------+ |
| 1 row in set (0.06 sec) |
