To retrieve structured type data from a table, there must be some way to convert that type into a single scalar value whose type, in turn, must be based on one of the built-in DB2 data types.

为了从表中检索结构化类型数据，必须有一些将类型转换成一个标量值，换句话说，这些值的类型必须基于某种内置的 DB2 数据类型。

It is always necessary to use the scalar function XML2CLOB (xml-data-type) : clob-data-type to serialize the XML contents in a clob data type.

总是有必要使用标量函数XML2CLOB (xml - data - type)： clob - data - type来将xml内容串行化为clob数据类型。
