目录
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
MeetingInfoDao:
// 待开会议
public List<Map<String, Object>> queryMeetingInfoByState(MeetingInfo info, PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException {
String sql="SELECT CONCAT(canyuze,',',liexize,',',zhuchiren),a.id,a.title,a.content,a.canyuze,a.liexize,a.zhuchiren,\r\n" +
" b.name zhuchirenname ,\r\n" +
" a.location,\r\n" +
" DATE_FORMAT(a.startTime,'%Y-%m-%d %H-%m-%s') startTime,\r\n" +

" and state = 4 and FIND_IN_SET("+info.getZhuchiren()+",CONCAT(canyuze,',',liexize,',',zhuchiren))";
return super.executeQuery(sql, pageBean);
}
// 所有会议

OA会议项目内容就到此结束啦~再见
