9.38 OPG_APIS.GET_LATLONG_FROM_V_COL
Format
OPG_APIS.GET_LATLONG_FROM_V_COL( v IN NVARCHAR2, srid IN NUMBER DEFAULT 8307 ) RETURN SDO_GEOMETRY;
Description
Returns an SDO_GEOMETRY object constructed using spatial data and optionally an SRID value.
Parameters
Usage Notes
This function assumes that for each vertex in the geometry in the v
parameter, the first number is the latitude value and the second number is the longitude value. (This is the reverse of the order in an SDO_GEOMETRY object definition, where longitude is first and latitude is second).
If there is incorrect syntax or a parsing error, this function returns NULL instead of generating an exception.
Examples
The following example returns a point SDO_GEOMETRY object. Notice that the coordinate values of the input point are “swapped” in the returned SDO_GEOMETRY object.
