Java 数据表“全部”选项，“显示100个条目中的1到0”

我有一个选项卡式数据表，我想将“全部”选项添加到我的菜单长度中

我有10个、25个、50个、75个条目，它们都可以正常工作，但是“all”选项返回100个条目中的1到0。。。在firebug中，我可以看到选择“全部”的数据为空。我是否缺少一个特定的参数？谢谢

<select id = "getPage" parameterType="map" resultType="com.ti.ds.psi.domain.Data">
    SELECT * FROM (
    SELECT rownum rn, s.* FROM (
    SELECT item1, item2
    FROM items
    WHERE upper(item1) like '%'||upper(#{sSearch_0})||'%'
    AND upper(item2) like '%'||upper(#{sSearch_1})||'%'
    ORDER BY
    <choose>
        <when test="sidx==0">item1</when>
        <when test="sidx==1">item2</when>
    </choose>
    ${sord}
    ) s
    )
    WHERE rn BETWEEN #{start} AND #{start} + #{rows}
</select>

修正了。。我在查询中添加了一个简单的片段-'或{rows}=-1'

“行”定义为我的表长度

谢谢。

我们需要更多信息来回答您的问题。对不起，在我完成之前按enter键。为什么您要给参数aLengthMenu而不是lengthMenu？当您单击“全部”时，请求不会以iDisplayLength=-1发送？如何在service.getPage中处理此问题？@CarlosCalla使用lengthMenu代替aLengthMenu仅显示默认选择
