MySQL 5.6 Reference Manual  /  ...  /  Functions That Create Geometry Values from WKT Values

12.15.3 Functions That Create Geometry Values from WKT Values

These functions take as arguments a Well-Known Text (WKT) representation and, optionally, a spatial reference system identifier (SRID). They return the corresponding geometry.

GeomFromText() and ST_GeomFromText() accept a WKT value of any geometry type as their first argument. Other functions provide type-specific construction functions for construction of geometry values of each geometry type.

For a description of WKT format, see Section 11.5.3.1.1, “Well-Known Text (WKT) Format”.
