Convert date in varchar field

I moved data from one database to another, one of the fields that was moved is a date and put into a varchar field. I won't get into details but it has to be like that.

Right now it displays the date as:  Jan  1 2014 12:00AM

I need to update the whole column for all records so that it reads as:  mm/dd/yyyy  (01/01/2014)

SQL Something like:

Update users
set DOB = NEW value where DOB = 'current value'

Help is appreciated

First try this:

select dob, convert(varchar, dob, 101) as newdob
from users

if that gives the desired result, then:

update users
set dob = convert(varchar, dob, 101)

UPDATE users
set DOB = format(convert(datetime, 'Feb 3 2014 1:00PM'),'MM/dd/yyyy')

I'm assuming that, since your destination field is DOB, and your target field is DOB, then you are converting a varchar to a varchar. If not, use David's solution.

I am using MS SQL 2008, tried the above got this error:

Msg 195, Level 15, State 10, Line 2
'format' is not a recognized built-in function name.

and what is that date in the query ?   I don't know what the date is, it changes on every row and I need to convert the date in all rows.

There is something wrong in the statement

Msg 207, Level 16, State 1, Line 15
Invalid column name 'DOB'.

DOB will be the name of the column you want to convert

select convert(varchar, convert(datetime, fieldnametoconvert), 101)
from table

The query you entered above doesn't specify the table, I think that might be necessary.

This actually shows the date in the correct format, so .. how do we update the column to have that value ?

select convert(varchar, convert(datetime, Dob), 101)
 from BDotSiskindSusser.dbo.Users
 WHERE DOB IS NOT null

the above only selects, we need to UPDATE  :)
