SQL

create table example(MONTH VARCHAR(MAX),ORDERS VARCHAR(MAX))

INSERT INTO example VALUES('Jan','1');
INSERT INTO example VALUES('Feb','2');
INSERT INTO example VALUES('Mar','3');

SELECT* FROM example
SELECT  'Assign' Assign ,*,'Total' [Total] into #final  from (SELECT * FROM example) AS A pivot(MAX(ORDERS) FOR[MONTH] IN(a,b,c)) AS pvt
select * from #final
DROP table #final

it need to show the month name instead of a,b,c it is a dynamic table so month name will change everytime

What I have tried:

First your in clause of query is wrong. Correct way of doing it is

DECLARE @TBL TABLE
(
MONTH VARCHAR(MAX),
ORDERS VARCHAR(MAX)
)

INSERT INTO @TBL VALUES('Jan','1');
INSERT INTO @TBL VALUES('Feb','2');
INSERT INTO @TBL VALUES('Mar','3');

SELECT  'Assign' Assign ,*,'Total' [Total] 
from 
(
	SELECT * FROM @TBL
) AS A pivot(MAX(ORDERS) FOR[MONTH] IN(Jan,Feb,Mar)) AS pvt

Secondly since columns are dynamic in nature hence a dynamic pivot query is required which is quite simple. Try these links for an idea.

Try below query as columns are coming dynamically

create table #temp
(
MONTH VARCHAR(MAX),
ORDERS VARCHAR(MAX)
)

INSERT INTO #temp VALUES('Jan','1');
INSERT INTO #temp VALUES('Feb','2');
INSERT INTO #temp VALUES('Mar','3');
INSERT INTO #temp VALUES('Feb','7');

DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX),
@cols1 AS NVARCHAR(MAX)

select @cols1=(SELECT ',' + QUOTENAME(MONTH)
from #temp order by orders
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)')

select @cols=STUFF(@cols1
,1,1,'' )

set @query = 'SELECT ' + @cols + '
from
(
select MONTH, ORDERS
from #temp
) x
pivot
(
max(ORDERS)
for MONTH in (' + @cols + ')
) p '
print @query

execute(@query)
