[dancer-users] Complex Query ?

[Hugues]

Hello  David
query works well with  $sth->fetchall_arrayref but the result with 
template toolkit doesn'work.

return template 'result' => {
                                   resultC      => $sth->fetchall_arrayref,

}


data are here on we page, I can see with DUMP

[% USE Dumper %]
[% Dumper.dump(resultC) %]

$VAR1 = [ [ '0003908', 'MME xxxx ANGELE', 'TOULON SUR ALLIER', '7248' ], 
[ '00923', 'DR CHLIER VICOA', 'RUEIL MALMAISON', 'AC0605' ],
...
...
...
RRAOLIN', '121420171' ] ];


I use


[%  FOREACH item IN resultC %]
         <tr>
                 <td>[% loop.count %] - <a href="[% request.uri_base 
%]/detailClient/[% item.CodeClient %] "> [% item.CodeClient %]</a> </td>
                 <td>                   <a href="[% request.uri_base 
%]/detailClient/[% item.CodeClient %] "> [% item.NomClient %] </a>  </td>
                 <td>[% item.Ville %]</td>
                 <td>[% item.Adresse %]</td>
         </tr>
                 [%  END %]



loop.count works, there all lines but other fields are empty

my $sql =qq/SELECT Client.CodeClient , Client.NomClient,Client.Ville, 
ClientContrat.NumContrat FROM Client INNER JOIN  ClientContrat
                                   ON (Client.CodeClient = 
ClientContrat.CodeClient)
                                   WHERE Client.CodeClient LIKE ? LIMIT 10/;


do you have a idea ?


I try [% item.table.field %] without success

bye
Hugues.
