How do I remove redundant namespace in nested query when using FOR XML PATH

When using FOR XML PATH

Answer 1

An alternative solution I've seen is to add the XMLNAMESPACES declaration after building the xml into a temporary variable:

declare @xml as xml;
select @xml = (
select 
    a.c2 as "@species"
    , (select l.c3 as "text()" 
       from t2 l where l.c2 = a.c1 
       for xml path('leg'), type) as "legs"
from t1 a
for xml path('animal'))

;with XmlNamespaces( 'uri:animal' as an)
select @xml for xml path('') , root('zoo');
