ST_Geometry
定義
ST_Geometry は、WKT 表現からジオメトリを構築します。
ArcGIS で使用する空間テーブルを作成する場合は、ST_LineString などの ST_Geometry サブタイプを指定するよりも、ST_Geometry として列を作成することをお勧めします。
構文
Oracle
- ライン、ポリゴン、およびポイント
sde.st_geometry (wkt clob, srid integer)
- 最適化ポイント(これは extproc エージェントを起動しないため、より高速にクエリを処理します)
sde.st_geometry (x,y,z,m,srid)
多数のポイント データをバッチで挿入する場合は、最適化ポイントの作図を使用します。
- パラメータ対応の円
sde.st_geometry (x,y,z,m,radius,numPts,srid)
- パラメータ対応の楕円
sde.st_geometry (x,y,z,m,semiMajor,semiMinor,angle,numPts,srid)
- パラメータ対応の扇形
sde.st_geometry (x, y, z, m, startangle, endangle, outerradius, innerradius, numPts, srid)
PostgreSQL
- ライン、ポリゴン、およびポイント
sde.st_geometry (wkt, srid integer) sde.st_geometry (esri_shape bytea, srid integer)
- パラメータ対応の円
sde.st_geometry (x,y,z,m,radius,numPts,srid)
- パラメータ対応の楕円
sde.st_geometry (x,y,z,m,semiMajor,semiMinor,angle,numPts,srid)
- パラメータ対応の扇形
sde.st_geometry (x, y, z, m, startangle, endangle, outerradius, innerradius, numPts, srid)
戻り値のタイプ
ST_Geometry
例
ポイント、ライン ストリング、およびポリゴン フィーチャの作成と検索
geoms テーブルを作成します。
CREATE TABLE geoms (id integer, geometry sde.st_geometry);
ポイント、ライン ストリング、およびポリゴンの値を geoms に挿入します。
Oracle
INSERT INTO GEOMS (id, geometry) VALUES (
1901,
sde.st_geometry ('point (1 2)', 0)
);
--To insert the same point using optimized point construction:
INSERT INTO GEOMS (id, geometry) VALUES (
1901,
sde.st_geometry (1,2,null,null,0)
);
INSERT INTO GEOMS (id, geometry) VALUES (
1902,
sde.st_geometry ('linestring (33 2, 34 3, 35 6)', 0)
);
INSERT INTO GEOMS (id, geometry) VALUES (
1903,
sde.st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 0)
);
PostgreSQL
CREATE TABLE geoms (id integer, geometry sde.st_geometry);
INSERT INTO geoms (id, geometry) VALUES (
1901,
sde.st_geometry ('point (1 2)', 0)
);
INSERT INTO geoms (id, geometry) VALUES (
1902,
sde.st_geometry ('linestring (33 2, 34 3, 35 6)', 0)
);
INSERT INTO geoms (id, geometry) VALUES (
1903,
sde.st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 0)
);
geoms テーブルからジオメトリを選択します。
Oracle
SELECT id, sde.st_astext (geometry) geometry
FROM GEOMS;
ID GEOMETRY
1901 POINT (1.00000000 2.00000000)
1902 LINESTRING (33.00000000 2.00000000, 34.00000000 3.00000000, 35.00000000 6.00000000)
1903 POLYGON ((3.00000000 3.00000001, 5.00000000 3.00000000, 4.00000000 6.00000000, 3.00000000 3.00000000))
PostgreSQL
SELECT id, st_astext (geometry) AS geometry
FROM geoms;
id geometry
1901 POINT (1 2)
1902 LINESTRING (33 2, 34 3, 35 6)
1903 POLYGON ((3 3, 5 3, 4 6, 3 3))
パラメータ対応の円の作成と検索
radii という名前のテーブルを作成し、円を挿入します。
Oracle
CREATE TABLE radii (id integer, geometry sde.st_geometry);
INSERT INTO RADII (id, geometry) VALUES (
1904,
sde.st_geometry (10,10,NULL,NULL,25,50,0)
);
INSERT INTO RADII (id, geometry) VALUES (
1905,
sde.st_geometry (5,15,NULL,NULL,10,20,0)
);
PostgreSQL
CREATE TABLE radii (id integer, geometry sde.st_geometry);
INSERT INTO radii (id, geometry) VALUES (
1904,
sde.st_geometry (10,10,NULL,NULL,25,50,0)
);
INSERT INTO radii (id, geometry) VALUES (
1905,

パラメータ対応の扇形の作成と検索
pwedge という名前のテーブルを作成し、扇形を挿入します。
Oracle
CREATE TABLE pwedge (uid integer, label varchar2(8), shape sde.st_geometry);
INSERT INTO PWEDGE (uid, label, shape) VALUES (
1,
'Wedge1',
sde.st_geometry (10,30,NULL,NULL,45,145,5,2,60,4236)
);
PostgreSQL
CREATE TABLE pwedge (uid integer, label varchar(8), shape sde.st_geometry);
INSERT INTO pwedge (uid, label, shape) VALUES (
1,
'Wedge',
sde.st_geometry(10,30,NULL,NULL,45,145,5,2,60,4236)
);
テーブルを検索して、ジオメトリ値をテキストで返します。
Oracle
SELECT label,
w.shape.minx,w.shape.miny,w.shape.maxx,w.shape.maxy,
w.shape.area,w.shape.len,w.shape.entity entity
FROM pwedge w;
PostgreSQL
SELECT label,
sde.st_minx(w.shape), sde.st_miny(shape),
sde.st_maxx(shape), sde.st_maxy(shape),
sde.st_area(shape), sde.st_length(shape), sde.st_geometrytype(shape)
FROM pwedge w;
