Convert date period to display a date format

Question

I have a SQL query which displays yyyymm in the following:

select  ([dimdate_fact_transac_TrnServiceDtId].[date_period]) as [date_period]
from [db].[dbo].[table]

Displays:

date_period
201304
201305
201306

How can I modify so the date_period comes out as MMM-YY like this:

date_period
APR-13
MAY-13
JUN-13

I am trying to do that for my SSRS report, but when I change the number format it doesn't show the date, which makes me believe it is sending it as a string rather than a date format.

Please help...

Answer 1

Following should do:

 FORMAT(Fields!Date.Value, "MMM-yy")

Answer 2

Edit:

Added a much cleaner version (1a) in SQL 2012

Method 1a

For SQL 2012 You can use the Format and DateFromParts method

SELECT FORMAT(DATEFROMPARTS(date_period/100, date_period % 100, 1), 'MMM-yy')

Method 1b

Handle it in SQL 2008/2005

SELECT 
LEFT(DATENAME(MONTH, 
                 CAST(date_period AS VARCHAR(6)) + '01'
            ), 
     3) 
+ 
'-' 
+ 
RIGHT(datePART(YY, CAST(date_period AS VARCHAR(6)) + '01'
              ), 
      2) 

as myDatePeriod

Method 2

Handle it in SSRS

=LEFT(MonthName
          (RIGHT(Fields!D.Value,2))
      ,3) 
& "-"
& Mid(Fields!D.Value,3,2)

Note: Added extra CRLF/spaces to make code readable
