Oracle Database Errors or Warnings from Error ORA-30934 to ORA-30943
ORA-30934: ‘string’ (string node) cannot be inserted in parent ‘string’ (string node)
Cause: The schema does not allow a child node of this type to be inserted into a parent node of this type. For example, only element nodes may only be inserted into a document
Action: Insert only child nodes that make sense for this node type
ORA-30935: XML maxoccurs value (string) exceeded
Cause: An attempt was made to insert more than maxoccurs values into a schema-based XML document.
Action: Do not insert more than maxoccurs values into the document.
ORA-30936: Maximum number (string) of ‘string’ XML node elements exceeded
Cause: An attempt was made to insert more than the allowed number of elements (specified by the maxoccurs facet) into an XML document.
Action: Do not attempt to add more than the maximum number of elements to XML documents.
ORA-30937: No schema definition for ‘string’ (namespace ‘string’) in parent ‘string’
Cause: The schema definition for the parent node being processed does not allow for the specified child node in its content model. Note that any typecasting via xsi:type must occur before the schema definitions for the new type can be used.
Action: Only insert elements and attributes declared in the schema. Check to make sure that xsi:type (if used) is specified first.
ORA-30938: No prefix defined for namespace ‘string’ (particle string)
Cause: An XML namespace mapping (xmlns:<prefix>=<namespace URL>) 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.
ORA-30939: Order violation: Element ‘string’ may not follow element ‘string’
Cause: The XML schema specifies a content model that is sequential, where the order of nodes in the instance must follow the order specified by the schema, and this instance relies on the schema validity to avoid maintaining instance order information
Action: Insert elements only in the order specified in the schema
ORA-30940: Cannot resolve prefix ‘string’ for QName node ‘string’
Cause: An attempt was made to store a QName value without having a valid namespace in scope for that prefix.
Action: Declare the namespace for the prefix used
ORA-30941: Cannot specify empty URI for non-default namespace ‘string’
Cause: An attempt was made to insert a namespace declaration for a non-default namespace using an empty URI string.
Action: Specify a non-empty URI for namespace declarations other than the default namespace. ////// Errors 30942 to 30950 reserved for XML Schema Evolution
ORA-30942: XML Schema Evolution error for schema ‘string’ table string column ‘string’
Cause: The given XMLType table/column which conforms to the given schema had errors during evolution. For more information, see the more specific error below this one
Action: Based on the schema, table and column information in this error and the more specific error below, take corrective action
ORA-30943: XML Schema ‘string’ is dependent on XML schema ‘string’
Cause: Not all dependent schemas were specified and/or the schemas were not specified in dependency order, i.e., if schema S1 is dependent on schema S, S must appear before S1.
Action: Include the previously unspecified schema in the list of schemas and/or correct the order in which the schemas are specified. Then retry the operation.
