[sql] how to convert date to a format `mm/dd/yyyy`

I'm having a sql table with date column named CREATED_TS which holds the dates in different format eg. as shown below

Feb 20 2012 12:00AM
11/29/12  8:20:53 PM          
Feb 20 2012 12:00AM
11/29/12  8:20:53 PM          
Feb 20 2012 12:00AM
11/29/12  8:20:53 PM          
Nov 16 2011 12:00AM
Feb 20 2012 12:00AM
11/29/12  8:20:52 PM

Now I want to convert these to format mm\dd\yyyy before as i am comparing the dates in WHERE clause of my SELECT query.

I tried using

CONVERT(VARCHAR(10),CREATED_TS,101)

but got the result as,

Feb 20 201
11/29/12  
Feb 20 201
11/29/12  
Feb 20 201
11/29/12  
Nov 16 201
Feb 20 201
11/29/12  

I need the result as eg. 02/20/2012 in order to compare.

Any help will be appreciated.

Use CONVERT with the Value specifier of 101, whilst casting your data to date:

CONVERT(VARCHAR(10), CAST(Created_TS AS DATE), 101)

Are you looking for something like this?

SELECT CASE WHEN LEFT(created_ts, 1) LIKE '[0-9]' 
            THEN CONVERT(VARCHAR(10), CONVERT(datetime, created_ts,   1), 101)
            ELSE CONVERT(VARCHAR(10), CONVERT(datetime, created_ts, 109), 101)
      END created_ts
  FROM table1

Output:

| CREATED_TS |
|------------|
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 11/16/2011 |
| 02/20/2012 |
| 11/29/2012 |

Here is SQLFiddle demo

Use:

select convert(nvarchar(10), CREATED_TS, 101)

or

select format(cast(CREATED_TS as date), 'MM/dd/yyyy') -- MySQL 3.23 and above
