This can be done using the following SQL function (CONVERT):
SELECT CONVERT([data type], [value to convert], [style])
The values inside the  should be replaced with the values you would use:
[data type] = This is the target data type to be converted. In your case, it would be datetime.
[value to convert] = the field in which you wish to convert to your desired date format.
[style] = the format in which you would like to convert to. In your case, this would be 3, but you can get a list of the options here.
