Return the property name for the specified sequence index.
If the sequence item is unstructured text rather than a
data object property, then a value of NULL is returned.
参数
sequenceIndex
The sequence index for which we wish to determine the associated
data object property name.
返回值
The corresponding property name.
A value of NULL means the element does not belong to a property
and must therefore be unstructured text.
异常
SDO_IndexOutOfBoundsException
Thrown if the sequence index is less than zero or greater than the
size of the sequence.
