With DateRange(dt) As
(
    Select Convert(Datetime, '01/01/2012')
    UNion All
    Select DateAdd(dd, 1, Dat.dt) From DateRange Dat Where Dat.dt < CONVERT(Datetime, '01/31/2012')
)

Select T.pName, Dt.dt from #temp T
Inner Join DateRange Dt on Dt.dt BETWEEN T.DateBegin and T.DateEnd

Drop Table #temp

问题出在以下代码行

With DateRange(dt) As

显示以下错误消息

Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.

添加一些分号:

create table #temp
(
  pName Varchar(20),
  DateBegin DateTime,
  DateEnd DateTime
)

Insert Into #temp(pName, DateBegin, DateEnd)
Values('Player1', '01/04/2012', '01/05/2012')

Insert Into #temp(pName, DateBegin, DateEnd)
Values('Player2', '02/01/2012', '02/05/2012');

With DateRange(dt) As
(
    Select Convert(Datetime, '01/01/2012')
    UNion All
    Select DateAdd(dd, 1, Dat.dt) From DateRange Dat Where Dat.dt < CONVERT(Datetime, '01/31/2012')
)

Select T.pName, Dt.dt from #temp T
Inner Join DateRange Dt on Dt.dt BETWEEN T.DateBegin and T.DateEnd;

Drop Table #temp
