OA项目之待开会议＆历史会议＆所有会议
2022-07-30 03:17:00 【小陈爱吃糖①】
目录
一、待开会议&所有会议SQL编写
-- 待开会议
-- 与我的会议区别在于 待开会议需要匹配3个数据库列段而我的会议只要匹配主持人就可以了
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) )
运行：
-- 所有会议
select 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,
