Order By Month Name in Sql-Server - sql

Question

I have Below Table named session
SessionID SessionName
100 August
101 September
102 October
103 November
104 December
105 January
106 May
107 June
108 July
I executed the following query I got the output as below.
Select SessionID, SessionName
From dbo.Session
SessionID SessionName
100 August
101 September
102 October
103 November
104 December
105 January
106 May
107 June
108 July
the results get ordered by Session ID. But I need the output as below,
SessionID SessionName
106 May
107 June
108 July
100 August
101 September
102 October
103 November
104 December
105 January
How to achieve this in sql-server? thanks for the help

Answer 1

I'd use a case expression, like:
order by case SessionName when 'August' then 1
when 'September' then 2
...
when 'Juty' then 12
end
August has 1 because "in the application logic a session started with august", easy to renumber if you want to start with January and end with December.

Answer 2

To avoid any hassel with culture dependencies, you might get the month's index out of sys languages with a query like this:
(I'd eventually create a TVF from this and pass in the langid as parameter)
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) MyMonthIndex
,Mnth.value('.','varchar(100)') AS MyMonthName
FROM
(
SELECT CAST('<x>' + REPLACE(months,',','</x><x>') + '</x>' AS XML) AS XmlData
FROM sys.syslanguages
WHERE langid=0
) AS DataSource
CROSS APPLY DataSource.XmlData.nodes('/x') AS The(Mnth)
The result
1 January
2 February
3 March
4 April
5 May
6 June
7 July
8 August
9 September
10 October
11 November
12 December
EDIT: An UDF for direct usage (e.g. in an order by)
CREATE FUNCTION dbo.GetMonthIndexFromMonthName(#MonthName VARCHAR(100),#langId INT)
RETURNS INT
AS
BEGIN
RETURN
(
SELECT MyMonthIndex
FROM
(
SELECT CAST(ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS INT) MyMonthIndex
,Mnth.value('.','varchar(100)') AS MyMonthName
FROM
(
SELECT CAST('<x>' + REPLACE(months,',','</x><x>') + '</x>' AS XML) AS XmlData
FROM sys.syslanguages
WHERE langid=#langId
) AS DataSource
CROSS APPLY DataSource.XmlData.nodes('/x') AS The(Mnth)
) AS tbl
WHERE MyMonthName=#MonthName
);
END
GO
SELECT dbo.GetMonthIndexFromMonthName('February',0)

Answer 3

I think you can do something like this:
SELECT * FROM session
ORDER BY MONTH(session.SessionName + ' 1 2014')
The part:
MONTH(session.SessionName + ' 1 2014')
Will return 3 of the month is march and you do not really need to care about the year in this case

Answer 4

Try CAST your Month Name (SessionName) into DATETIME format, just like this
SELECT * FROM table
ORDER BY DATEPART(mm, CAST(SessionName + '1900' AS DATETIME)) asc

Answer 5

You can convert the string month into number and sort by numer form month
SELECT SessionID, SessionName, DATEPART(MM, SessionName)
FROM dbo.Session
ORDER BY DATEPART(MM, SessionName)
otherwise, if you have something like "DateCreation" column, you can do something like this
SELECT SessionID, SessionName, MONTH(DateCreation)
FROM dbo.Session
ORDER BY MONTH(DateCreation)

Answer 6

Try with this .. I am assuming that you want next month of current Date is starting point so I am using "Month(GetDate()" in script otherwise you can hard-code to 4 to get desired result
Declare #Session Table (SessionID INT, SessionName Varchar(20))
Insert Into #Session Values (100,'August'),(101,'September'),(102,'October'),(103,'November'),(104,'December')
,(105,'January'),(106,'May'),(107,'June'),(108,'July')
Select * From #Session
ORDER BY CASE WHEN Month(CAST('01-' + SessionName + ' 2016' AS DateTime)) - Month(GetDate()) <= 0
THEN 12 + Month(CAST('01-' + SessionName + ' 2016' AS DateTime)) - Month(GetDate())
ELSE Month(CAST('01-' + SessionName + ' 2016' AS DateTime)) - Month(GetDate()) END
For GERMAN Language ..use below script .. In this i used soundex for month comparision
SET LANGUAGE GERMAN;
Declare #Session Table (SessionID INT, SessionName Varchar(20))
Insert Into #Session Values (100,'August'),(101,'September'),(102,'October'),(103,'November'),(104,'December')
,(105,'January'),(106,'May'),(107,'June'),(108,'July')
Select * From #Session S
INNER JOIN
(SELECT Number + 1 as [MonthNumber],
DateName(mm,DATEADD(mm,Number,0)) as [MonthName]
FROM master..spt_values
WHERE Type = 'P' and Number < 12
)M ON SoundEx(M.MonthName)=SoundEx(S.SessionName)
ORDER BY CASE WHEN [MonthNumber] - Month(GetDate()) <= 0
THEN 12 + [MonthNumber] - Month(GetDate())
ELSE [MonthNumber] - Month(GetDate()) END
