XML Data Type Mapping(3.0)

XML Data Type Mapping(3.0)

Apr 20, 2023

XML data types are automatically mapped to data types in Ultra as follows:


XML Type
Ultra Type
<integer types>int, except for long and unsignedLong. These data types are mapped to bigint.
float float
double double
dateTime date
anyType The AnyType UDR. See AnyType UDR Type(3.0).
<all other types>string


The mapping of the data types also depends on the element attribute maxOccurs. When the value of this attribute is greater than 1 (one) or unbounded, the mapped field is of list type.

When the element attribute minOccurs is 0 (zero), the field is considered optional and can be omitted in the internal format.

Declared attributes are considered mandatory or optional, depending on the use attribute:

  • required - The field is mandatory.
  • optional (default) - The field is optional.
  • prohibited - The use attribute is ignored and the field is optional.
     

Example - Mapping of element- and attribute types

element name="REQUEST"> 
 <complexType>
 <!-- Mapped to string, mandatory -->
 <attribute name="REQUEST_ID" type="string" use="required"/>
 <sequence> 
 <!-- Mapped to string, mandatory -->
 <element name="ITEM" type="string" minOccurs="1" maxOccurs="1"/>  
 
  <!-- Mapped to list<string>, mandatory -->
 <element name="A_ITEMS" type="string" minOccurs="1" maxOccurs="2"/>  
 
  <!-- Mapped to list<string>, mandatory -->
 <element name="B_ITEMS" type="string" minOccurs="1" maxOccurs="unbounded"/>  
 
  <!--Mapped to string, optional->
 <element name="C_ITEMS" type="string" minOccurs="0" maxOccurs="1"/> 
 </sequence>
 </complexType>
</element>
