31.6 INSERT_GEOM_METADATA_LONLAT Procedure

This procedure inserts a spatial metadata record that is suitable for longitude/latitude and optionally creates a spatial index.

Syntax

APEX_SPATIAL.INSERT_GEOM_METADATA_LONLAT (
    p_table_name        IN VARCHAR2,
    p_column_name       IN VARCHAR2,
    p_tolerance         IN NUMBER DEFAULT 1,
    p_create_index_name IN VARCHAR2 DEFAULT NULL );

Parameters

Table 31-6 INSERT_GEOM_METADATA_LONLAT Parameters

Parameter	Description
`p_table_name`	Name of the feature table.
`p_column_name`	Name of the column of type `mdsys.sdo_geometry`.
`p_tolerance`	Tolerance value in each dimension, in meters (default 1).
`p_create_index_name`	if not null, a spatial index on the column is created with this name. Only simple column names are supported, function based indexes or indexes on object attributes cause an error. For more complex requirements, leave this parameter null (the default) and manually create the index.

Example

The code below creates table CITIES and spatial metadata for the column CITIES.SHAPE. By passing CITIES_IDX_SHAPE to p_create_index_name, the API call automatically creates an index on the spatial column.

create table cities (
    city_id   number primary key,
    city_name varchar2(30),
    shape     mdsys.sdo_geometry )
/
begin
    apex_spatial.insert_geom_metadata_lonlat (
        p_table_name        => 'CITIES',
        p_column_name       => 'SHAPE',
        p_create_index_name => 'CITIES_IDX_SHAPE' );
end;
/
