ORA-54560: query element cannot be a collection or multitype geometry

ORA-54560: query element cannot be a collection or multitype geometry
Cause: A query element was a collection geometry or a multitype geometry. Such geometries are not permitted in a query element because they are at the top of the geometry hierarchy. A query element must be part of the source geometry.
Action: Redefine the query element or the source geometry so that a label can be output.

ORA-54560：query元素不能是集合或多元素几何,
.原因：查询元素是集合几何或多元素几何。在查询元素中不允许使用此类几何，因为它们位于几何层次结构的顶部。查询元素必须是源几何的一部分。,
.操作：重新定义查询元素或源几何，以便可以输出标签。,
