Oracle 复杂sql 语句,在线等.....
表结构如下:
CREATE TABLE [dbo].[recordInfo](
[id] [int] IDENTITY(1,1) NOT NULL primary key ,
[name] [varchar](20) NOT NULL, --姓名
[recorddate] [varchar](20) NULL, --工作时间
[workhours] [numeric](10, 2) NULL) --工作小时

数据如下:
id name recorddate workhours  
1 sa 2012-06-10 8.00
2 sa 2012-06-11 8.00
3 root 2012-06-11 9.00
4 root 2012-06-14 7.00
5 admin 2012-06-15 6.00
6 sa 2012-06-10 3.00

现在需要查询2012-06-10至2012-06-15用户的数据

查询每个人每天的总共工作小时数据,没有默认workhours为0

需要的结果

admin 2012-06-10 0.00
admin 2012-06-11 0.00
admin 2012-06-12 0.00
admin 2012-06-13 0.00
admin 2012-06-14 0.00
admin 2012-06-15 6.00
root 2012-06-10 0.00
root 2012-06-11 9.00
root 2012-06-12 0.00
root 2012-06-13 0.00
root 2012-06-14 7.00
root 2012-06-15 0.00
sa 2012-06-10 11.00
sa 2012-06-11 8.00
sa 2012-06-12 0.00
sa 2012-06-13 0.00
sa 2012-06-14 0.00
sa 2012-06-15 0.00

貌似是写复杂了点 还没怎么想 应该还有简单的吧 大概就这思路了

SQL code
select t3.name,t3.r_date,to_char(nvl(sum(t4.workhours),0),'FM99990.00') workhoursfrom(select distinct name,r_datefrom (select n_date+level-1 r_date from (select max(recorddate) m_date,min(recorddate) n_date from recordInfo) connect by level <= m_date-n_date+1) t2,recordInfo t1) t3 left join recordInfo t4 on t3.name = t4.name and t3.r_date = t4.recorddategroup by t3.name,t3.r_dateorder by t3.name,t3.r_date      name     r_date     workhours-----------------------------------------1    admin    2012/6/10    0.002    admin    2012/6/11    0.003    admin    2012/6/12    0.004    admin    2012/6/13    0.005    admin    2012/6/14    0.006    admin    2012/6/15    6.007    root    2012/6/10    0.008    root    2012/6/11    9.009    root    2012/6/12    0.0010    root    2012/6/13    0.0011    root    2012/6/14    7.0012    root    2012/6/15    0.0013    sa    2012/6/10    11.0014    sa    2012/6/11    8.0015    sa    2012/6/12    0.0016    sa    2012/6/13    0.0017    sa    2012/6/14    0.0018    sa    2012/6/15    0.00
