SQL-Server-2005

Dear All,

I have the following stored proc:

SQL

ALTER proc [dbo].[BINDDAYS] --3
(
@Month BIGINT
)
as
begin
set nocount on

declare @temp table
(
RowId BIGINT IDENTITY,
NewDate nvarchar(50)
)

declare @NewDate datetime,@MAX bigint,@MIN bigint

select @NewDate=CAST(CAST(@Month AS VARCHAR(10))+'/01/2011' 
AS DATETIME)
select @MAX=DAY(DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@NewDate)+1,0))),@MIN=1


WHILE(@MIN<=@MAX)
BEGIN
SET @NewDate=CAST(CAST(@Month AS VARCHAR(10))+'/'+CAST(@MIN 
AS VARCHAR(10))+'/2011' AS DATETIME)
INSERT INTO @temp(NewDate) SELECT CONVERT(NVARCHAR(50),@NewDate,103)
SET @MIN=@MIN+1
END

select RowId,NewDate FROM @temp

end

Here, I am able to display all the days for a specific month(you can see the month no. i.e.,3 as a parameter) as 1/3/2011,2/3/2011......31/3/2011.

But now I want to pass the "day" as a parameter and get the date format.
Ex: If I pass 24, then it should display 24/1/2011,24/02/2011......24/12/2011.

Any help or suggestion greatly appreciable...

I'd say get rid of what you've got already. You've got hardcoded strings in there!!

SQL

CREATE PROCEDURE  GetAllDaysForMonth

	(
		@Date			DATETIME
	)

AS

SET NOCOUNT ON

DECLARE @CurrentDate DATETIME
DECLARE @FirstDate DATETIME 
DECLARE @LastDate DATETIME 

DECLARE @Days TABLE (DateField DATETIME)

--Find first day of the month
SET @FirstDate =  CAST (FLOOR( CAST(DateAdd(Day, 1, @Date - Day(@Date) + 1) -1 AS FLOAT)) AS DATETIME)

--Find last day of the month
SET @LastDate =  CAST (FLOOR( CAST(DateAdd(Month, 1, @Date - Day(@Date) + 1) -1 AS FLOAT)) AS DATETIME)

--Set start of the loop
SET @CurrentDate = @FirstDate

--Loop until the 'last day of the month' and insert into table variable
While @CurrentDate <= @LastDate
  Begin
     Insert Into @Days Values(@CurrentDate)
     Set @CurrentDate = DateAdd(d,1,@CurrentDate)
  End 

--Return all days in the month
Select * From @Days


-- Return any error codes \ Reset the NOCOUNT property.
RETURN @@ERROR
SET NOCOUNT OFF
GO

Usage as follows...

SQL

DECLARE @TheDate DATETIME
SET @TheDate = GETDATE()
EXEC [GetAllDaysForMonth] @TheDate

Not able to understand... Can u plz tell me according to my procedure..?

Dylan Morley 4-Mar-11 7:41am

What bit don't you understand. It's simpler than your procedure, and every line is commented!!

Raj.rcr 4-Mar-11 7:43am

I tried but its displaying the different format for a specific day. I want the date to be displayed as say, if I pass the day 24 as a parameter, then it should display

24/01/2011
24/02/2011
.
.
.
.
24/12/2011.I hope u undrstd now.

It's a date format, what difference does it make how it looks? It's not SQL Servers job to present data in a particular format.

*That's the job of your user interface*

Get the data back from SQL Server, then your interface should determine how the data is presented to the user.

e.g in c# string.Format or ToShortDateString() or whatever.

OK see my other solution with procedure 'GetAllMonthsForDay'

Solution 2

This is modified version of Dylan's solution (hope you don't mind) using "common table expression (CTE)"

SQL

CREATE PROCEDURE  GetAllDaysForMonth
    (
        @Date           DATETIME
    )
AS
SET NOCOUNT ON

DECLARE @FirstDate DATETIME 
DECLARE @LastDate DATETIME 

--Find first day of the month
SET @FirstDate =  CAST (FLOOR( CAST(DateAdd(Day, 1, @Date - Day(@Date) + 1) -1 AS FLOAT)) AS DATETIME)

--Find last day of the month
SET @LastDate =  CAST (FLOOR( CAST(DateAdd(Month, 1, @Date - Day(@Date) + 1) -1 AS FLOAT)) AS DATETIME)

--Return all days in the month
;WITH DT AS
(
SELECT DateField    = @FirstDate
UNION ALL
SELECT  DateField+1
FROM    DT
WHERE   DateField   < @LastDate
)
SELECT  *
FROM    DT

nice

Solution 3

Ah I think I see what the OP wants now...

instead of 'All Days for a Month' he wants 'All Months for a Day'

Same sort of thing, just slight logic change. Usage same as before

SQL

CREATE PROCEDURE  GetAllMonthsForDay
	(
		@Date			DATETIME
	)
AS

SET NOCOUNT ON

DECLARE @CurrentDate DATETIME
DECLARE @FirstDate DATETIME 
DECLARE @LastDate DATETIME 

DECLARE @Months TABLE (DateField DATETIME)
DECLARE @Day INT
DECLARE @Year INT

--The day in the date
SET @Day = DATEPART (d , @Date )
SET @Year = DATEPART(yyyy, @Date )

SET @FirstDate = CAST(CAST(1 AS varchar) + '-' + CAST(@Day AS varchar) + '-' + CAST(@Year AS varchar) AS DATETIME)

SET @LastDate = CAST(CAST(12 AS varchar) + '-' + CAST(@Day AS varchar) + '-' + CAST(@Year AS varchar) AS DATETIME)

--Set start of the loop
SET @CurrentDate = @FirstDate

--Loop until the 'last day of the month' and insert into table variable
While @CurrentDate <= @LastDate
  Begin
     Insert Into @Months Values(@CurrentDate)
     Set @CurrentDate = DateAdd(m,1,@CurrentDate)
  End 

--Return all days in the month
Select * From @Months


-- Return any error codes \ Reset the NOCOUNT property.
RETURN @@ERROR
SET NOCOUNT OFF
GO

But from the op question he just want to pass day as the parameter instead of complete date.

OK, final one...!

You only pass day to this + it will handle all possible date permutations. e.g if you pass 31 to this as date, it will just get the 'last date available' in months that don't have 31 days

SQL

CREATE PROCEDURE  [dbo].[GetAllMonthsForDay]
	(
		@Day	INT
	)
AS

SET NOCOUNT ON

DECLARE @CurrentDate DATETIME
DECLARE @FirstDate DATETIME 
DECLARE @LastDate DATETIME 

DECLARE @Today DATETIMe
DECLARE @Months TABLE (DateField DATETIME)
DECLARE @Year INT

IF (@Day < 1 OR @Day > 31)
BEGIN
	RAISERROR('Invalid day specified for date function', 16, 1)
	RETURN
END

SET @Today = GETDATE()

--The day in the date
SET @Year = DATEPART(yyyy, @Today )
SET @FirstDate = CAST(CAST(1 AS varchar) + '-' + CAST(@Day AS varchar) + '-' + CAST(@Year AS varchar) AS DATETIME)
SET @LastDate = CAST(CAST(12 AS varchar) + '-' + CAST(@Day AS varchar) + '-' + CAST(@Year AS varchar) AS DATETIME)

--Set start of the loop
SET @CurrentDate = @FirstDate

--Loop until the 'last day of the month' and insert into table variable
While @CurrentDate <= @LastDate
  Begin
     Insert Into @Months Values(@CurrentDate)

     --If date has changed, it could be because we've tried to increment a value that is not valid
     --e.g 31st won't exist in February	
     IF (DATEPART(dd, @CurrentDate) != @Day)
     BEGIN
         Set @CurrentDate = DateAdd(m,1,@CurrentDate)
         SET @CurrentDate = CAST(CAST(DATEPART(mm, @CurrentDate) AS varchar) + '-' + CAST(@Day AS varchar) + '-' + CAST(@Year AS varchar) AS DATETIME)
     END
	 ELSE
	 BEGIN
         Set @CurrentDate = DateAdd(m,1,@CurrentDate)
     END     
  End 

--Return all days in the month
Select * From @Months


-- Return any error codes \ Reset the NOCOUNT property.
RETURN @@ERROR
SET NOCOUNT OFF
