项目场景：

前端是leyui后端sqlserver和maraDB进行分页,两种数据库在后端分页的不同写法

解决方案：

前端:

定义table,表格的格式在接口返回时进行创建,根据id进行绑定

 <div class="layui-tab-item layui-show" style="padding-top: 10px">
        <div class="layui-card-body" style="padding:20px 0px;width: 100%">
          <table class="layui-hide" id="Distribution" lay-filter="Distribution"></table>
        </div>
      </div>

此处用于定于表格的表头处的按钮

<script type="text/html" id="toolbarDemo">
  <div class="layui-btn-container">
    <button type="button" class="layui-btn layui-btn-sm" style="background-color: #1E9FFF" id="button1" lay-event="day">今日配送
    </button>
    <button type="button" class="layui-btn layui-btn-normal layui-btn-sm" id="button2" style="background-color: #FFB800"  lay-event="week">本周配送
    </button>
    <button type="button" class="layui-btn layui-btn-normal layui-btn-sm" id="button3"  style="background-color: #FF5722"  lay-event="month">本月配送
    </button>
    <button type="button" class="layui-btn layui-btn-normal layui-btn-sm" id="button4" lay-event="all">查看全部</button>
  </div>
</script>

 定义url和参数以及table和表头处的id选择集

toolbar: '#toolbarDemo', 接收表头id

elem: '#Distribution', 接收table的id

以下是生成的表格样式和分页效果

下面是后端分页

同样需要将page和limit传入后端并接收

sqlserver和maraDB一样只是业务层和sql不一样

业务层

sqlserver直接传就行

maraDB则需要计算一下

最后是sql的不同

sqlserver

select top ${limit} * from (
            SELECT
                ISNULL( CAST ( a.disposeStatus AS VARCHAR ), '--' ) AS disposeStatus,
                COALESCE(CONVERT(VARCHAR(100), a.alarmTime, 120), '--') AS alarmTime,
                ISNULL( CAST ( b.concNumber AS VARCHAR ), '--' ) AS concNumber,
                ISNULL( CAST ( a.alarmValue AS VARCHAR ), '--' ) AS alarmValue,
                ISNULL( CAST ( a.alarmCause AS VARCHAR ), '--' ) AS alarmCause
            FROM
                DKGasRun.dbo.AlarmDis AS a,
                DKGovtGas.dbo.Concentration AS b
            WHERE
                a.equipID = b.ID
                AND b.companyID = #{comId}
                <if test="alarmCause=''||alarmCause!=null">
                    AND a.alarmCause LIKE'%' + #{alarmCause} + '%'
                </if>
        ) n
        where rownumber > ((${page} - 1)*${limit})

maraDB

  SELECT
            ISNULL( CAST ( a.disposeStatus AS VARCHAR ), '--' ) AS disposeStatus,
            COALESCE(CONVERT(VARCHAR(100), a.alarmTime, 120), '--') AS alarmTime,
            ISNULL( CAST ( b.concNumber AS VARCHAR ), '--' ) AS concNumber,
            ISNULL( CAST ( a.alarmValue AS VARCHAR ), '--' ) AS alarmValue,
            ISNULL( CAST ( a.alarmCause AS VARCHAR ), '--' ) AS alarmCause
            FROM
             dkgasrun.alarmd AS a,
             dkgovtgas.concentration AS b
            WHERE
            a.equipID = b.ID
            AND b.companyID = #{comId}
            <if test="alarmCause=''||alarmCause!=null">
                AND a.alarmCause LIKE CONCAT('%', #{alarmCause}, '%')
            </if>
             limit #{page},#{limit};
