一、待开会议&所有会议SQL编写

待开会议：

当前登录账号，只要是某会议的参与者、列席者、主持人中的一员，并且会议状态是待开，则查询出来。

（与我的会议的区别在于：待开会议需要匹配3个数据库列段）

SQL：

SELECT CONCAT(canyuze,',',liexize,',',zhuchiren),a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,
b.name zhuchirenname ,
a.location,
DATE_FORMAT(a.startTime,'%Y-%m-%d %H-%m-%s') startTime,
DATE_FORMAT(a.endTime,'%Y-%m-%d %H-%m-%s') endTime,
a.state,
(
	case a.state
	when 0 then'取消会议'
	when 1 then'新建'
	when 2 then'待审核'
	when 3 then'驳回'
	when 4 then'待开'
	when 5 then'进行中'
	when 6 then'开启投票'
	when 7 then'结束会议'
	else '其他' end
) meetingstate,
a.seatPic,a.remark,a.auditor,
c.name auditorname from t_oa_meeting_info a
inner join t_oa_user b on a.zhuchiren =b.id
left join t_oa_user c on a.auditor = c.id where 1=1  
and state = 4 and FIND_IN_SET(6,CONCAT(canyuze,',',liexize,',',zhuchiren))

所有会议：

当前登录账号，只要是某会议的参与者、列席者、主持人、审批人中的一员，那么必须查出来。

 SQL：

SELECT CONCAT(a.canyuze,',',a.liexize,',',a.zhuchiren,',',IFNULL(a.auditor
,-1)),a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,
b.name zhuchirenname ,
a.location,
DATE_FORMAT(a.startTime,'%Y-%m-%d %H-%m-%s') startTime,
DATE_FORMAT(a.endTime,'%Y-%m-%d %H-%m-%s') endTime,
a.state,
(
	case a.state
	when 0 then'取消会议'
	when 1 then'新建'
	when 2 then'待审核'
	when 3 then'驳回'
	when 4 then'待开'
	when 5 then'进行中'
	when 6 then'开启投票'
	when 7 then'结束会议'
	else '其他' end
) meetingstate,
a.seatPic,a.remark,a.auditor,
c.name auditorname from t_oa_meeting_info a
inner join t_oa_user b on a.zhuchiren =b.id
left join t_oa_user c on a.auditor = c.id where 1=1  
 and FIND_IN_SET(6,CONCAT(a.canyuze,',',a.liexize,',',a.zhuchiren,',',IFNULL(a.auditor
,-1)))

二、待开会议及所有会议功能开发

    });
}

//2.查询所有会议
function query(){
    table.reload('tb_meeting', {
        url: 'info.action',     //请求地址
        method: 'POST',                    //请求方式，GET或者POST

        page: true,                        //是否分页
        where: {                           //设定异步数据接口的额外参数，任意设
            'methodName':'allInfos',
            'title':$('#title').val(),
            'zhuchiren':$('#userid').val()
        },
        request: {                         //自定义分页请求参数名
