我的数据表是一张每月值班表,记录每天各个岗位是谁值班.一个岗位只有一人值班
我现在想统计每个月每个人在每个岗位上值班的次数(周六 周天另外统计).
表样式:
年 月 日 星期 岗位1 岗位2 岗位3 岗位4
2007 10 11 5 黄 张 ... ...
2007 10 12 6 张 黄
输出样式大概是这样
姓名 岗位1 岗位2 岗位3 周六(日)
黄 2次 1次 3次 2次
请问各路 大虾 帮我出个主意 该怎么查询 比较好

- SQL code
动态得到，但是没有链接成一个表create table tb(y int,m int ,d int,w int,gw1 varchar(10),gw2 varchar(10), gw3 varchar(10))insert tbselect 2007,2,3,1,'黄','王','李' union allselect 2007,2,4,2,'张','张','张' union allselect 2007,2,8,6,'王','黄','张' union allselect 2007,3,1,4,'张','王','黄' union allselect 2007,3,4,7,'李','张','黄' union allselect 2007,4,2,1,'张','黄','黄' union allselect 2007,4,3,2,'黄','王','王' union allselect 2007,5,1,2,'黄','张','张' union allselect 2007,5,2,3,'王','张','王' union allselect 2007,5,3,4,'李','王','李' union allselect 2007,5,4,5,'王','黄','黄' union allselect 2007,5,5,6,'张','王','黄' union allselect 2007,5,6,7,'黄','张','王' union allselect 2007,5,7,1,'张','张','张' union allselect 2007,6,7,1,'王','黄','李'select distinct gw as [name], identity(int,1,1) as id into #tempTable from (select gw1 as gw from tb union all select gw2 as gw from tb union all select gw3 as gw from tb) as tdeclare @i intset @i=(select count(*) from #tempTable)declare @k intset @k=1declare @sql varchar(500) while @i>[email protected] begin set @sql = 'Select Top 1 * into #tempTable' + convert(varchar(5),@k)+ ' From #tempTable Where id in (Select Top '+ convert(varchar(5),@k)+' id From #tempTable) Order by id desc' set @sql = @sql +' select #tempTable'+ convert(varchar(5),@k)+ '.[name], sum(case when gw1=#tempTable'+ convert(varchar(5),@k)+ '.[name] then 1 else 0 end) as gw1,sum(case when gw2=#tempTable'+ convert(varchar(5),@k)+ '.[name] then 1 else 0 end) as gw2,sum(case when gw3=#tempTable'+ convert(varchar(5),@k)+ '.[name] then 1 else 0 end) as gw3, sum(case when gw2=#tempTable'+ convert(varchar(5),@k)+ '.[name] and (w=6 or w=7) then 1 else 0 end) as '+ char(39)+'周六、日'+ char(39)+' from tb, #tempTable'+ convert(varchar(5),@k)+' group by name drop table #tempTable'+ convert(varchar(5),@k) set @[email protected]+1 exec(@sql) enddrop table tb,#tempTable/*name gw1 gw2 gw3 周六、日---------- ----------- ----------- ----------- -----------黄 4 4 5 1name gw1 gw2 gw3 周六、日---------- ----------- ----------- ----------- -----------李 2 0 3 0name gw1 gw2 gw3 周六、日---------- ----------- ----------- ----------- -----------王 4 5 3 1name gw1 gw2 gw3 周六、日---------- ----------- ----------- ----------- -----------张 5 6 4 2*/
