Oracle Spatial 创建空间表、添加空间原表信息、添加删除空间索引

一、创建空间表

创建一个空间表tbsvrc_buffer_t ，SQL如下：

create table tbsvrc_buffer_t
(
  ID      VARCHAR2(50) not null,
  SHAPE   MDSYS.SDO_GEOMETRY
) 其中SHAPE为SDO_GEOMETRY类型

二、添加空间元表信息

　　//插入空间原表信息
 insert into mdsys.sdo_geom_metadata_table(sdo_owner,sdo_table_name,
                                     sdo_column_name,
                                     sdo_diminfo,sdo_srid) values('GEOCATALOG','TBSVRC_BUFFER_T', 'SHAPE',mdsys.sdo_dim_array(mdsys.sdo_dim_element('x',
                                             -180,
                                             180,
                                             0.000005),
                       mdsys.sdo_dim_element('y',
                                             -90,
                                             90,
                                             0.000005),
                       mdsys.sdo_dim_element('z', 0, 0, 0.000005)),8307)

三、添加空间索引

//创建空间索引                    
  create index spatial_buffer_index on tbsvrc_buffer_t(shape) indextype is mdsys.SPATIAL_INDEX

四、删除空间索引

//删除空间索引
  DROP INDEX    spatial_buffer_index
