这样就能在idesktop中看到数据源了。

CREATE TABLE us_restaurants_new
(
id NUMBER,
poi_name VARCHAR2(32),
location MDSYS.SDO_GEOMETRY -- New column to store locations
);

--插入元数据
insert into user_sdo_geom_metadata(TABLE_NAME,COLUMN_NAME
,DIMINFO,SRID) values(
‘us_restaurants_new‘,
‘location‘,

MDSYS.SDO_DIM_ELEMENT(‘y‘,0.000000000,60.000000000,0.000000050)),

);

 

INSERT INTO us_restaurants_new VALUES
