我正在使用sql server 2008 r2.我试图在FromDate,Todate之间分配24小时的时间段.例如,如果时间行给出如下,(FromDate,Todate之间的范围是4天,所以我想要4行)

ID   FromDate                 Todate     
---- ------------------------ -------------------------
1    2014-04-01 08:00:00.000  2014-04-04 12:00:00.000

结果我想看到这样的结果:

ID   FromDate                 Todate                   DateDiff(HH)
---- ------------------------ -----------------------------------
