I'm trying to query a database with 'update table set column = column + 1 where...'..

Using zend_db_table I've tried with $table->update(array('column' => 'column+1', $where), but it hadn't worked.

Could somebody help me?

I've found out..

the key is to use Zend_Db_Expr.

$table->update(array('column' => new Zend_Db_Expr('column+ 1')), $where);
