9.34.8. Using Geometries in Client Applications and SQL Procedures
In SQL procedures, a geometry is a member of the ANY data type. The
isgeometry ()
function
can be used for testing if an object is a geometry. A geometry can only be stored in a column
declared to be of type ANY.
If a geometry would be returned to a client application as part of a result set, it is returned as a string containing its WKT text representation. For a client application to pass geometries to the server, it must pass these either as a WKT string parameter to st_geomfromtext or as numeric coordinate values for st_point or related functions. This applies to all clients, ODBC, JDBC, .net and any RDF frameworks.
