待开会议SQL

一、会议OA项目名词介绍

我的会议：当前登录账号，是某会议主持人，则查询出来
我的审批：当前登录账号，是某会议的指定审批人，并且会议状态是待审核，则查询出来
会议通知：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，并且该会议未反馈，则查询出来

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

历史会议：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，并且会议状态是结束，则查询出来

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，那么必须查询出来

二、SQL编写

待开会议SQL

待开会议与我的会议的区别：待开会议需要匹配3个数据库列段某会议的参与者、列席者、主持人


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


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SQL

这条SQL语句提供错误演示，不要运用在项目中👀

所有会议与待开会议的区别：所有会议不需要限制状态，并且需要新增一个审批人列段


select CONCAT(a.canyuze,',',a.liexize,',',a.zhuchiren,',',a.auditor),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

假设：id=6的用户，是会议OA的列席人员，会议OA又处于新建状态，意味着没有审批人，请问这条数据要不要查询出来？


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)))

如果当前会议还没有送审也就是没有审批人的情况下，我们需要用ifnull函数设它编号为-1，否则会发生数据丢失

三、代码阶段

待开会议
