This is fairly simple:
select
*,
MonthNumber = month([month]+' 1 2010')
from
( --test data
select [month] = 'January' union all
select [month] = 'April' union all
select [month] = 'September' union all
select [month] = 'December'
) a




Results:
month     MonthNumber
--------- -----------
January 1
April 4
September 9
December 12

(4 row(s) affected)

There've been a lot of answers to this question and they could all be unnecessary because SQL Server is very forgiving for most date formats. With that thought in mind, what does the original data look like? And I'm not just talking about the month name. For example, if your trying to convert a string to an SQL Datetime and the date looks like '1 June 2010', there you don't need to find the month number to do the conversion....

SELECT CAST('4 June 2010' AS DATETIME)






Your are genious , Jeff Moden

I like your simplicity.

Agreed. Jeff has a way with cutting to the chase and seeing what is really needed.

I've just found that this works in Reporting Services as well where Fields!Season_Month returns the month name only:

=Month("1 " & Fields!Season_Month.Value & " 2012")

Very forgiving indeed.


SELECT MONTH('April' + ' 1900')





My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!

you can simply do this by below code:
declare @table table (
dated varchar(50)
)

 insert into @table values('2017-feb-16')

 select * from @table

  select datepart(mm,dated) from @table

Go
