oracle - 无法删除空间数据库中的元数据条目

Question

I am trying to  a spatial data table in my db using :

CREATE TABLE building (buildid VARCHAR(15) PRIMARY KEY, buildname VARCHAR(50),numpoint NUMBER,points SDO_GEOMETRY);

CREATE INDEX building_spatial_idx ON building(points) INDEXTYPE IS MDSYS.SPATIAL_INDEX;

INSERT INTO USER_SDO_GEOM_METADATA(TABLE_NAME,COLUMN_NAME,DIMINFO,SRID) VALUES ('building', 'points', SDO_DIM_ARRAY(--820*580 grid SDO_DIM_ELEMENT('X', 0, 820, 1), SDO_DIM_ELEMENT('Y', 0 , 580, 1) ), 空 --SRID );

当我第一次执行它时，它没有给出任何错误，但后来它给出了错误

insert into user_sdo_geom_metadata values
*
ERROR at line 1:
ORA-00001: unique constraint (MDSYS.UNIQUE_LAYERS) violated
ORA-06512: at "MDSYS.SDO_GEOM_TRIG_INS1", line 27
ORA-04088: error during execution of trigger 'MDSYS.SDO_GEOM_TRIG_INS1'

Is it happening because am trying to give meta-data for same table again.

或者还有什么其他原因。如何一次删除所有索引、元数据、表并删除此错误。
