For better performance, consider creating a function-based index on this function. For more information, see Function-Based Indexes for FILTER Constructs Involving Typed Literals.

Examples

The following example returns TIMESTAMP WITH TIME ZONE values for all xsd:dateTime literals in the RDF_VALUE$ table:

SELECT SEM_APIS.GETV$DATETIMETZVAL(value_type, vname_prefix, vname_suffix,
  literal_type, language_type)
  FROM RDF_VALUE$;
