ST_MeshGeomFromWKB - - Alibaba Cloud Documentation Center

This topic describes the ST_MeshGeomFromWKB function. This function constructs a meshgeom object from the well-known binary (WKB) representation of the meshgeom object.

Syntax

meshgeom ST_MeshGeomFromWKB(bytea wkb);
meshgeom ST_MeshGeomFromWKB(bytea wkb, int4 srid);

Parameters


Parameter	Description
wkb	The meshgeom object in WKB representation.
srid	The spatial reference identifier.

Description

This function constructs a meshgeom object from the WKB representation of the meshgeom object.

Examples

select ST_AsEWKT(ST_MeshGeomFromWKB(ST_AsWKB('MESHGEOM(PATCH(INDEXSURFACE(VERTEX(0 0 2,0 10 3,10 10 1,10 0 1), INDEX((0,1,2),(1,2,3)))))'::meshgeom)));
                                   st_asewkt
