Answer 1

$statement = $this->sql->getSqlStringForSqlObject( HERE GOES Zend\Db\Sql\SelectSQL object );

echo "SQL statement: $statement";

Example:

$select = $this->sql->select();
...
$select->from(array( 'u' => 'users' ));
$select->join(...
$select->group('u.id');
...
$statement = $this->sql->getSqlStringForSqlObject($select);
echo $statement;
