ON— the interior and boundary of one object is on the boundary of the other object (and the second object covers the first object). This relationship occurs, for example, when a line is on the boundary of a po
开始我们可以理解它为ArcObjects中的Geometry对象(本来要素的shape字段中的对象就是Geometry),而不要理解他是怎么样组织的。至于该类型中的SDO_POINT_TYPE、SDO_ELEM_INFO_ARRAY、SDO_ORDINATE_ARRAY也是Oracle Spatial自定义的类型和 sdo_geometry 是一样的。 现在对sdo_geometry 类型中的各个参数简单的介绍: 1、SDO...
Spatial operators, such as SDO_FILTER and SDO_RELATE, provide optimumperformance because they use the spatial index. (Spatial operators require that the geometry column in the first parameter have a spatial index defined on it.) Spatialoperators must be used in the WHERE clause of a query. The...
Spatial data isany data with a location component. Databases with geographic references, suchas addresses, phone numbers and postal codes may now analyse this informationusing third party geocoding tools and services. The Oracle Spatial geocodingfeature matches these records with a latitude/longitude poi...
’ll need a table with a column of type SDO_GEOMETRY. This type is specifically designed to store the spatial attributes of an object. In this same table, you may also need to define columns of common types, such as VARCHAR2 and NUMBER, to hold nonspatial attributes of spatial objects....

由此可见,在 Oracle 中,无论是 u1 还是 u2 用户,调用存储过程时都能正确返回表名,说明两者查询user_tab_columns视图的返回结果是一致的,这也是符合预期的。 OB Oracle 环境中验证 代码语言:javascript 代码运行次数:0 运行 AI代码解释 --创建测试用户并赋权SYS[SYS]>create user u1 identified by u1;QueryOK,...
