sqlalchemy中使用query查询，而flask-sqlalchemy中使用basequery查询，他们是子类与父类的关系

1.用offset()设置索引偏移量,limit()限制取出量

db.session.query(User.name).filter(User.email.like(+email+)).limit(page_size).offset((page_index-1)*

2.用slice(偏移量，取出量)函数

db.session.query(User.name).filter(User.email.like(+email+)).slice((page_index – 1) * page_size,page_index *

注释：此方法和第一种相同的效果。

因为：由一下内部方法可知，slice()函数第一个属性就是offset()函数值，第二个属性就是limit()函数值

    <span style="color: #0000ff;"&gt;if</span> start <span style="color: #0000ff;"&gt;is</span> <span style="color: #0000ff;"&gt;not</span> None <span style="color: #0000ff;"&gt;and</span> stop <span style="color: #0000ff;"&gt;is</span> <span style="color: #0000ff;"&gt;not</span><span style="color: #000000;"&gt; None:
        self._offset </span>= (self._offset <span style="color: #0000ff;"&gt;or</span> 0) +<span style="color: #000000;"&gt; start
        self._limit </span>= stop -<span style="color: #000000;"&gt; start
    </span><span style="color: #0000ff;"&gt;elif</span> start <span style="color: #0000ff;"&gt;is</span> None <span style="color: #0000ff;"&gt;and</span> stop <span style="color: #0000ff;"&gt;is</span> <span style="color: #0000ff;"&gt;not</span><span style="color: #000000;"&gt; None:
        self._limit </span>=<span style="color: #000000;"&gt; stop
    </span><span style="color: #0000ff;"&gt;elif</span> start <span style="color: #0000ff;"&gt;is</span> <span style="color: #0000ff;"&gt;not</span> None <span style="color: #0000ff;"&gt;and</span> stop <span style="color: #0000ff;"&gt;is</span><span style="color: #000000;"&gt; None:
        self._offset </span>= (self._offset <span style="color: #0000ff;"&gt;or</span> 0) +<span style="color: #000000;"&gt; start

    </span><span style="color: #0000ff;"&gt;if</span> self._offset ==<span style="color: #000000;"&gt; 0:
        self._offset </span>=<span style="color: #000000;"&gt; None

@_generative(_no_statement_condition)
</span><span style="color: #0000ff;"&gt;def</span><span style="color: #000000;"&gt; limit(self,limit):
    </span><span style="color: #800000;"&gt;"""</span><span style="color: #800000;"&gt;Apply a ``LIMIT`` to the query and return the newly resulting

    ``Query``.

    </span><span style="color: #800000;"&gt;"""</span><span style="color: #000000;"&gt;
    self._limit </span>=<span style="color: #000000;"&gt; limit

@_generative(_no_statement_condition)
</span><span style="color: #0000ff;"&gt;def</span><span style="color: #000000;"&gt; offset(self,offset):
    </span><span style="color: #800000;"&gt;"""</span><span style="color: #800000;"&gt;Apply an ``OFFSET`` to the query and return the newly resulting
    ``Query``.

    </span><span style="color: #800000;"&gt;"""</span><span style="color: #000000;"&gt;
    self._offset </span>= offset</pre>

3.用paginate(偏移量，取出量)函数,用于BaseQuery

user_obj=User.query.filter(User.email.like(+email+
object_list =user_obj.items

4.filter中使用limit

db.session.query(User.name).filter(User.email.like(+email+) limit (page_index – 1) *
