如何在哪里获得"不平等"？

Question

我有这样的事情:

    $sql = new Sql($this->tableGateway->getAdapter());
    $select = $sql->select();

    $select
        -> from('mytable')
        -> join('exp', 'field1_id=field1.id', '*', 'LEFT');

    $where = new  Where();
    $where -> equalTo('field2_id', $field2_id);

    $select->where($where);

    $statement = $sql->prepareStatementForSqlObject($select);

但如果我想用"不等于",该怎么办？怎么做？

Answer 1

你需要使用notEqualTo

$where->notEqualTo('field2_id', $field2_id);
