使用一些样本数据…
create table data (begindate datetime, enddate datetime, data int);insert data select '20130101', '20130104', 7 union all select '20130105', '20130106', 9;
查询 ：（注意：如果您已经有一个数字/理货表格，请使用它）
select dateadd(d,v.number,d.begindate) adate, data from data d join master..spt_values v on v.type='P' and v.number between 0 and datediff(d, begindate, enddate)order by adate;
结果 ：
| COLUMN_0 | DATA |-----------------------------------------| January, 01 2013 00:00:00+0000 | 7 || January, 02 2013 00:00:00+0000 | 7 || January, 03 2013 00:00:00+0000 | 7 || January, 04 2013 00:00:00+0000 | 7 || January, 05 2013 00:00:00+0000 | 9 || January, 06 2013 00:00:00+0000 | 9 |
或者，您可以即时生成号码表（0-99），也可以根据需要生成任意数量的号码
;WITH Numbers(number) AS ( select top(100) row_number() over (order by (select 0))-1 from sys.columns a cross join sys.columns b cross join sys.columns c cross join sys.columns d )select dateadd(d,v.number,d.begindate) adate, data from data d join Numbers v on v.number between 0 and datediff(d, begindate, enddate)order by adate;
