选择月份的第一天到当前日期之间的所有日期

Question

只需选择月份日和月份的第一天之间的所有日期。我想用填写所有日期的临时表

declare @temp table 
(
    ddate datetime 
) 

我试图与with cte，我不想监守我想避免，而在存储过程，而循环使用。

例如今天是11-oct-2012

所以临时表中应该有11行从开始到1-oct-201211-oct-2012

Answer 1

试试这个

DECLARE @startDate DATE=CAST(MONTH(GETDATE()) AS VARCHAR) + '/' + '01/' + + CAST(YEAR(GETDATE()) AS VARCHAR) -- mm/dd/yyyy 
DECLARE @endDate DATE=GETDATE() -- mm/dd/yyyy 

SELECT [Date] = DATEADD(Day,Number,@startDate) 
FROM master..spt_values 
WHERE Type='P' 
AND DATEADD(day,Number,@startDate) <= @endDate 

OR

DECLARE @startDate DATETIME=CAST(MONTH(GETDATE()) AS VARCHAR) + '/' + '01/' + + CAST(YEAR(GETDATE()) AS VARCHAR) -- mm/dd/yyyy 
DECLARE @endDate DATETIME= GETDATE() -- mm/dd/yyyy 

;WITH Calender AS 
(
    SELECT @startDate AS CalanderDate 
    UNION ALL 
    SELECT CalanderDate + 1 FROM Calender 
    WHERE CalanderDate + 1 <= @endDate 
) 
SELECT [Date] = CONVERT(VARCHAR(10),CalanderDate,25) 
FROM Calender 
OPTION (MAXRECURSION 0) 

Answer 2

declare @temp table (ddate datetime); 

insert @temp 
select DATEDIFF(d,0,GetDate()-Number) 
from master..spt_values 
where type='p' and number < DatePart(d,Getdate()) 
order by 1;
