Alright the second worked. Thanks a lot.
using namespace std;
using namespace boost;
namespace fields
{
struct _id_;
struct _name_;
struct _birthday_;
struct _address_id_;
}
typedef fusion::map< fusion::pair< fields::_id_ , string >
, fusion::pair< fields::_name_ , string >
, fusion::pair< fields::_birthday_ , string >
, fusion::pair< fields::_address_id_, string >
> table_type;
int main()
{
table_type table;
vector< table_type > vec;
find_if( vec.begin()
, vec.end()
, bind( equal_to< string >()
, bind( &fusion::at_key< fields::_id_, table_type const >, _1 )
, string( "Hallo" )));
return 0;
}

test.cpp(43) : error C2783: 'result_of::at_key
::type boost::fusion::at_key(const Sequence &)' : could not deduce template argument for 'Sequence' Have you tried supplying the Sequence template parameter? Something like:
bind( &fusion::at_key< fields::_id_, table_type >, _1 )
or, if this doesn't work:
bind( &fusion::at_key< fields::_id_, table_type const >, _1 )
If this doesn't help, I'm afraid that your get_id wrapper is the best workaround. It's possible to cast &fusion::at_key<_id_> to the correct type, but I consider the get_id approach superior in general.
