Syntax
ST_AsBinary(g) AsBinary(g) ST_AsWKB(g) AsWKB(g)
Description
Converts a value in internal geometry format to its WKB representation and returns the binary result.
ST_AsBinary(), AsBinary(), ST_AsWKB() and AsWKB() are synonyms,
Examples
SET @poly = ST_GeomFromText('POLYGON((0 0,0 1,1 1,1 0,0 0))'); SELECT ST_AsBinary(@poly); SELECT ST_AsText(ST_GeomFromWKB(ST_AsWKB(@poly))); +--------------------------------------------+ | ST_AsText(ST_GeomFromWKB(ST_AsWKB(@poly))) | +--------------------------------------------+ | POLYGON((0 0,0 1,1 1,1 0,0 0)) | +--------------------------------------------+
