我遇到了SDO_RELATE的问题，它正在返回那些几何形状 不在里面
.geom不在myGeom（）中，但它仍然返回8个结果。
有没有人有任何想法？
查询：
select t.geom from GEOM_TABLE t where SDO_RELATE(t.geom, MDSYS.ST_GEOMETRY( mygeom() ).geom,'mask=INSIDE')= 'TRUE';
表GEOM_TABLE有8个GEOM：
MDSYS.SDO_GEOMETRY(2001,4326,MDSYS.SDO_POINT_TYPE(-0.0869771096384677,51.5024165642481,NULL),NULL,NULL)
