Oralce Spatial

1.建立数据库连接

create public database link ytlink
connect to hightop identified by hightop
using '(DESCRIPTION=
(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.137)(PORT=1521))
(CONNECT_DATA=
(SERVER = DEDICATED)(SERVICE_NAME = orcl))
)';

2.跨库查询

select * from police@ytlink

3.创建临时表空间

create temporary tablespace POLICE_TEMP --创建临时表空间
tempfile 'E:\app\Administrator\product\POLICE_TEMP.dbf'
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

4.删除表空间

drop tablespace POLICE_TEMP including contents and datafiles;--删除表空间

5.创建表空间

create tablespace POLICE --创建表空间
logging  
datafile 'E:\app\Administrator\product\POLICE.dbf' 
size 500m  
autoextend on  
next 500m maxsize 20480m  
extent management local;  

6.创建用户

create user hightop identified by "hightop" --创建用户并制定表空间
default tablespace POLICE  
temporary tablespace POLICE_TEMP;

7.删除用户

drop user hightop cascade;--删除用户

8.用户授权

grant all privileges to hightop;--给用户授予权限

9.shp上传oracle

1.shp2sdo shp文件名 表名 -i id -s 4326 -d（在shp2sdo所在路径下执行）
2.SQL> @J:\DY\表名.sql（在plsql的sql命令行执行或sqlplus下执行）
3.sqlldr 用户名/密码@实例名 表名（在安装oracle机器的dos执行）
4.SQL> execute sdo_migrate.to_current('表名','geometry字段名');
5.SQL> CREATE INDEX 索引名 ON 表名(geometry字段名) INDEXTYPE IS MDSYS.SPATIAL_INDEX;

10.空间关系计算

select c.id,s.id from tlmap_village c,cameragps s where sdo_geom.relate(s.geom,'Anyinteract',c.geom,0.000001)='TRUE' --计算点在面内

11.向mdsys.cs_srs中插入crs(以3857为例):

 insert into mdsys.cs_srs (cs_name, srid, auth_srid, wktext, wktext3d)
  values (
    'WGS_1984_Web_Mercator_Auxiliary_Sphere',
    3857,
    3857,
    'PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Mercator_Auxiliary_Sphere"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",0.0],PARAMETER["Standard_Parallel_1",0.0],PARAMETER["Auxiliary_Sphere_Type",0.0],UNIT["Meter",1.0]]',
    ''
);

12.SDO_SRID不为NULL时，SDO_SRID必须在MDSYS.CS_SRS 表中的 SRID 列有对应的值，而且它的值必须插入USER_SDO_GEOM_METADATA视图中。
