会议OA项目（待开会议&所有会议）

一、SQL语句

待开会议

待开会议
-- 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
-- 区别就在于state


-- 待开会议
-- 与我的会议的区别在于，代开会议需要匹配3个数据库列段
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-%s')startTime,

	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

所有会议

只是新建状态，还没有对应审核人也应该查询出来
