将日期格式从mmddyy转换为yyyy-mm-dd hh：mm：sec

Question

I have a date format which I extracted from filename. this date is in format 'mmddyy' .

I want to convert it into 'yyyy-mm-dd hh:mm:sec' format.

For example Date = 083115 -- mm = 08,dd=31,yy=15

Result date = 2015-08-31:00:00:00 time will always be 00:00:00

I am using SQL server 2012

thanks

Answer 1

Here is a solution

DECLARE @Date nvarchar(10)
SET @Date = '083115'
SELECT  CONVERT(datetime,RIGHT(@Date,2)+LEFT(@Date,2)+SUBSTRING(@Date,3,2))

this will give you 2015-08-31 00:00:00.000
