oracle空间索引创建
–1)、插入空间索引元数据
insert into mdsys.sdo_geom_metadata_table
(sdo_owner, sdo_table_name, sdo_column_name, sdo_diminfo)
values
(‘GWM_TEST’, –索引用户名
‘GS_DYNAMIC_GRID_P’, –表名称
‘GWM_GEOMETRY’, –空间字段
mdsys.sdo_dim_array(mdsys.sdo_dim_element(‘x’,
-5000000,
5000000,
0.000005),
mdsys.sdo_dim_element(‘y’,
-5000000,
5000000,
0.000005),
mdsys.sdo_dim_element(‘z’, 0, 0, 0.000005)));
–2)、查询空间索引元数据,首先要向该视图插入一条记录,确保有一条对应的记录,方可进行第三步
select * from user_sdo_geom_metadata;
–3)、创建空间索引
CREATE INDEX IDX_GS_dynamic_grid_P_SPATIAL ON gs_dynamic_grid_p(gwm_geometry) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
–删除空间索引
drop index IDX_GS_dynamic_grid_P_SPATIAL;
–查询空间索引元数据
select * from mdsys.sdo_geom_metadata_table;
–查询空间索引
select INDEX_NAME,
TABLE_OWNER,
TABLE_NAME,
STATUS,
ITYP_OWNER,
ITYP_NAME,
DOMIDX_STATUS,
DOMIDX_OPSTATUS
from user_indexes
where ITYP_NAME is not null;
