Question

I have the following query

Select field1 as 'node1/field1',        field2 as 'node1/field2',   (Select field3 as 'child1/field3',           field4 as 'child1/field4'    From table2    FOR XML PATH(''),TYPE,Elements) From Table1 FOR XML PATH('Root'),Elements 

This produces:

<Root>   <node1>     <field1>data1</field1>     <field2>data2</field2>   </node1>    <child1>      <field3>data3</field3>      <field4>data4</field4>    </child1>    <child1>      ...    </Root> 

I would like the child1 nodes to be part of node1, not a separate node below.

<Root>   <node1>     <field1>data1</field1>     <field2>data2</field2>     <child1>        <field3>data3</field3>        <field4>data4</field4>     </child1>     <child1>       ...  </node1>  <node1>    ... </Root> 

I’ve tried putting node1 in the subquery PATH

FOR XML PATH('node1'),TYPE,Elements) 

or prefixing the subquery field names with node1

Select field3 as 'node1/child1/field3', 

but both create a new node1 element for the subquery.

Does anyone know how I can accomplish this?

Thanks

You’ve gotta tell SQL Server how table1 and table2 are related. Based on your answer below, I think something like this might do the trick:

select      table1.field1 as 'Node1/Field1' ,   table2.field1 as 'Node1/Child1/Field1' ,   table1.field2 as 'Node2/Field2' from table1 left join table2 on table1.id = table2.table1id for xml PATH(''), ROOT('Root') 

This should produce XML like:

<Root>     <Node1>         <Field1>Value</Field1>         <Child1>             <Field1>Value</Field1>         </Child1>     </Node1>     <Node2>         <Field2>Value</Field2>     </Node2> </Root>
