The syntax for declaring an SDO-based variable is similar to that for declaring BPEL variables. The following example provides details.

<variable name="deptVar_s" element="hrtypes:dept" />
<variable name="deptVar_v" element="hrtypes:dept" bpelx:sdoCapable="false" />

If you want to override the automatic detection, use the bpelx:sdoCapable="true|false" switch. For example, variable deptVar_v described in the preceding sample is a regular DOM-based variable. The following example shows an XSD sample:

<xsd:element name="dept" type="Dept"/>
   <xsd:complexType name="Dept"
    sdoJava:instanceClass="sdo.sample.service.types.Dept">
      <xsd:annotation>
         <xsd:appinfo source="Key"
          xmlns="http://xmlns.oracle.com/bc4j/service/metadata/">
            <key>
               <attribute>Deptno</attribute>
            </key>
            <fetchMode>minimal</fetchMode>
         </xsd:appinfo>
      </xsd:annotation>
      <xsd:sequence>
         <xsd:element name="Deptno" type="xsd:integer" minOccurs="0"/>
         <xsd:element name="Dname" type="xsd:string" minOccurs="0"
 nillable="true"/>
         <xsd:element name="Loc" type="xsd:string" minOccurs="0" nillable="true"/>
         <xsd:element name="Emp" type="Emp" minOccurs="0" maxOccurs="unbounded"
 nillable="true"/>
      </xsd:sequence>
   </xsd:complexType>
