csharp 演示使用select属性仅检索相关项的name属性的Aras最佳实践。

Posted 2021-05-12

Item workflow = this.newItem("Workflow","get");
// use the select attribute to retrieve only the name property of the related item
workflow.setAttribute("select", "related_id(name)");
Item workflowProcess = workflow.createRelatedItem("Workflow Process","get");
Item workflowProcessActivity = workflowProcess.createRelationship("Workflow Process Activity","get");
Item activity = workflowProcessActivity.createRelatedItem("Activity", "get");
activity.setID('activityId');
workflow = workflow.apply();

// generates the following AML query
// same effect as adding select="name" to the Workflow Process item
// <AML>
//   <Item type="Workflow" action="get" select="related_id(name)">
//     <related_id>
//       <Item type="Workflow Process" action="get"> 
//         <Relationships>
//           <Item type="Workflow Process Activity" action="get">
//             <related_id>
//               <Item type="Activity" action="get" id="activityId"/>
//             </related_id>
//           </Item>
//         </Relationships>
//       </Item>
//     </related_id>
//   </Item>
// </AML>
