ORA-30938: No prefix defined for namespace string (particle string)

ORA-30938: No prefix defined for namespace string (particle string)

Cause: An XML namespace mapping (xmlns:lamp;lt;lamp;nbsp;prefixlamp;gt;=lamp;lt;lamp;nbsp;namespace URLlamp;gt;) must be defined for each particle (element or attribute) stored in an schema-constrained XMLType document.

Action: Add an xmlns attribute definition (attribute name= xmlns:prefix and value= namespace URL ) to the current XMLType document. The safest place to add this attribute is in the root node of the document to ensure that the mapping will be in scope.
