symfony 1.4 doctrine 1.2 - 创建用户友好的查询/更新

Question

I have table in mysql:

id | num1 | num2| num 3| num3| num5|
1  | 6    | 3   | 4    | 2   | 1   |

in sql I do for example:

$num = num2; 
$val = 2;
$id  = 2;

$sql = "update TABLE set '$num'='$val' where id='$id'";
mysql_query( $sql);

I can do with $val and $id , but I have a problem with $num ...

how to do this in Doctrine 1.2?

Answer 1

Try something like this:

$q = Doctrine_Query::create()
    ->update('TABLE')
    ->set($num, '?', $val)
    ->where('id = ?', $id)
    ->execute();
