Get a list of dates between two dates using a function

Question

My question is similar to this MySQL question, but intended for SQL Server:

Is there a function or a query that will return a list of days between two dates? For exa

Answer 1

Declare @date1 date = '2016-01-01'
              ,@date2 date = '2016-03-31'
              ,@date_index date
Declare @calender table (D date)
SET @date_index = @date1
WHILE @date_index<=@date2
BEGIN
INSERT INTO @calender
SELECT @date_index

SET @date_index = dateadd(day,1,@date_index)

IF @date_index>@date2
Break
ELSE
Continue
END

Answer 2

Answer is avialbe here How to list all dates between two dates

Create Procedure SelectDates(@fromDate Date, @toDate Date)
AS
BEGIN
    SELECT DATEADD(DAY,number,@fromDate) [Date]
    FROM master..spt_values
    WHERE type = 'P'
    AND DATEADD(DAY,number,@fromDate) < @toDate

END

Answer 3

Perhaps if you wish to go an easier way, this should do it.

WITH date_range (calc_date) AS (
    SELECT DATEADD(DAY, DATEDIFF(DAY, 0, CURRENT_TIMESTAMP) - 6, 0)
        UNION ALL SELECT DATEADD(DAY, 1, calc_date)
            FROM date_range
            WHERE DATEADD(DAY, 1, calc_date) < CURRENT_TIMESTAMP)
SELECT calc_date
FROM date_range;

But the temporary table is a very good approach also. Perhaps shall you also consider a populated calendar table.

Answer 4

In case you want to print years starting from a particular year till current date. Just altered the accepted answer.

WITH mycte AS
    (
      SELECT YEAR(CONVERT(DATE, '2006-01-01',102)) DateValue
      UNION ALL
      SELECT  DateValue + 1
      FROM    mycte   
      WHERE   DateValue + 1 < = YEAR(GETDATE())
    )
    SELECT  DateValue
    FROM    mycte

OPTION (MAXRECURSION 0)

Answer 5

I'm an oracle guy, but I believe MS SQL Server has support for the connect by clause:

select  sysdate + level
from    dual
connect by level <= 10 ;

The output is:

SYSDATE+LEVEL
05-SEP-09
06-SEP-09
07-SEP-09
08-SEP-09
09-SEP-09
10-SEP-09
11-SEP-09
12-SEP-09
13-SEP-09
14-SEP-09

Dual is just a 'dummy' table that comes with oracle (it contains 1 row and the word 'dummy' as the value of the single column).

Answer 6

-- ### Six of one half dozen of another. Another method assuming MsSql

Declare @MonthStart    datetime   = convert(DateTime,'07/01/2016')
Declare @MonthEnd      datetime   = convert(DateTime,'07/31/2016')
Declare @DayCount_int       Int   = 0 
Declare @WhileCount_int     Int   = 0

set @DayCount_int = DATEDIFF(DAY, @MonthStart, @MonthEnd)
select @WhileCount_int
WHILE @WhileCount_int < @DayCount_int + 1
BEGIN
   print convert(Varchar(24),DateAdd(day,@WhileCount_int,@MonthStart),101)
   SET @WhileCount_int = @WhileCount_int + 1;
END;
