예: EXPLICIT 모드를 사용하여 형제 구성
적용 대상: SQL Server Azure SQL Database Azure SQL Managed Instance
판매 주문 정보를 제공하는 XML을 생성한다고 가정합니다. 이 예제에서 <SalesPerson>
<OrderDetail>
요소는 형제입니다. 각 Order에는 <OrderHeader>
요소 및 <SalesPerson>
요소가 하나씩 있고 하나 이상의 <OrderDetail>
요소가 있습니다.
<OrderHeader SalesOrderID=... OrderDate=... CustomerID=... >
<SalesPerson SalesPersonID=... />
<OrderDetail SalesOrderID=... LineTotal=... ProductID=... OrderQty=... />
<OrderDetail SalesOrderID=... LineTotal=... ProductID=... OrderQty=.../>
...
</OrderHeader>
<OrderHeader ...</OrderHeader>
다음 EXPLICIT 모드 쿼리는 이 XML을 생성합니다. 쿼리는 <OrderHeader>
요소에 대해 1, Tag
요소의 경우 2, <OrderDetail>
요소에 대해 3의 <SalesPerson>
값을 지정합니다. <SalesPerson>
및 <OrderDetail>
은(는) 형제이기 때문에 이 쿼리는 같은 Parent
태그 값으로 1을 지정하여 <OrderHeader>
요소를 식별합니다.
