sql server - Sql return results as xml -


given data:

fname     lname   apartmentnumber ----------------------------------- david    shumer      1 john     deer        1 mark     ratz        2 steven   styer       2

i return xml, did this:

select * table1  xml raw('person'), root('peopleinapartment'), elements

and got result

<peopleinapartment>   <person>     <fname>david</fname>     <lname>shumer</lname>     <apartmentnumber>1</apartmentnumber>   </person>   <person>     <fname>john</fname>     <lname>deer</lname>     <apartmentnumber>1</apartmentnumber>   </person>   <person>     <fname>mark</fname>     <lname>ratz</lname>     <apartmentnumber>2</apartmentnumber>   </person>   <person>     <fname>steven</fname>     <lname>styer</lname>     <apartmentnumber>2</apartmentnumber>   </person> </peopleinapartment>

is possible group people apartment result this?:

<apartments>     <peopleinapartment>       <person>         <fname>david</fname>         <lname>shumer</lname>         <apartmentnumber>1</apartmentnumber>       </person>       <person>         <fname>john</fname>         <lname>deer</lname>         <apartmentnumber>1</apartmentnumber>       </person>     </peopleinapartment>     <peopleinapartment>       <person>         <fname>mark</fname>         <lname>ratz</lname>         <apartmentnumber>2</apartmentnumber>       </person>       <person>         <fname>steven</fname>         <lname>styer</lname>         <apartmentnumber>2</apartmentnumber>       </person>     </peopleinapartment> </apartments>

sql solution. note subquery must depend on outer columns in group by, t1.apartmentnumber specifically.

select t1.apartmentnumber   , (select t2.fname, t2.lname      table1  t2      t2.apartmentnumber = t1.apartmentnumber      xml path('person'), type       )  peopleinapartment table1  t1 group apartmentnumber xml path('apartment'), root('apartments'), elements

returns data apartment - wise

<apartments>     <apartment>         <apartmentnumber>1</apartmentnumber>         <peopleinapartment>             <person>                 <fname>david </fname>                 <lname>shumer</lname>             </person>             <person>                 <fname>john  </fname>                 <lname>deer  </lname>             </person>         </peopleinapartment>     </apartment>     <apartment>         <apartmentnumber>2</apartmentnumber>         <peopleinapartment>             <person>                 <fname>mark  </fname>                 <lname>ratz  </lname>             </person>             <person>                 <fname>steven</fname>                 <lname>styer </lname>             </person>         </peopleinapartment>     </apartment> </apartments>
