OR，和使用Zend \\ Db \\ Sql \\ Sql的Where

Question

I'm trying to change this normal SQL statment, where I use "where" with or, to a Zend\\Db\\Sql\\Sql Object.

However I cant figure out how to write the "where" clause.

this is the code before:

 SELECT column 
 FROM Table
 WHERE value = num OR value2 = num

and this is how i'm trying to make it look like:

 $sql = new Sql($adapter);
 $select = $sql->select();
 $select->from(Table);
 $select->where(?);

Answer 1

In simple case, only have AND. You can use

$select ->where(array('cloumn1'=>'A', 'column2'=>'B'));

In complex case:

$where = new \Zend\Db\Sql\Where();

$where
    ->nest()
    ->equalTo('table1.column2', 2)
    ->or
    ->equalTo('table1.column3', 3)
    ->unnest()
    ->and
    ->equalTo('table1.column1', 1);
$select->where($where)
