创建、插入空间信息表

对经纬度坐标，坐标系统一定要用 8307，否则结果不正确！

CREATE TABLE MyGeom
(
id NUMBER,
name VARCHAR2(35),
geom SDO_GEOMETRY
);

插入圆形

INSERT INTO MyGeom VALUES
(
1,
'圆形',
SDO_GEOMETRY
(
    2003, -- SDO_GTYPE: 二维多边形
    8307, -- 大地坐标
    NULL, -- SDO_POINT_TYPE is null
    SDO_ELEM_INFO_ARRAY -- SDO_ELEM_INFO attribute (see Table 4-2 for values)
    (
      1, -- Offset is 1
      1003, -- 多边形
      4 -- 圆形
    ),
    SDO_ORDINATE_ARRAY -- SDO_ORDINATES attribute
    (
111.788889,28.318333,
112.633783,28.315394,
112.291389,27.621667
    )
)
);

插入多边形

INSERT INTO MyGeom VALUES
(
2,
'多边形',
SDO_GEOMETRY
(
    2003, -- SDO_GTYPE: 二维多边形
    8307, -- 大地坐标系
    NULL, -- SDO_POINT_TYPE is null
    SDO_ELEM_INFO_ARRAY -- SDO_ELEM_INFO attribute (see Table 4-2 for values)
    (
      1, -- Offset is 1
      1003, -- 多边形
      1 -- Interpretation is 1 if line string is connected by straight lines.
    ),
    SDO_ORDINATE_ARRAY -- SDO_ORDINATES attribute
    (
112.291389,27.621667,
112.633333,26.908333,
112.358333,25.561667,
111.340000,25.276667,
109.316667,26.583333,
109.355833,27.882500,
111.788889,28.318333,

    )
