Grouping WHERE clauses with Zend_Db_Table_Abstract

Question

Does anyone know of a way to group where clauses with Zend_Db? Basically I have this query

$sql = $table->select()
             ->where(\'company_id =          


        

Answer 1

In first you can generate subquery, then get "WHERE" part and insert into main query

$subquery = $db->select();
$subquery->orWhere('a>10');
$subquery->orWhere('b<20');
etc..

$subquery = $subquery->getPart(Zend_Db_Select::WHERE);
$select->where(implode(' ',$subquery));
