You can also use FORMAT(X, D) in your query:

Formats the number X to a format like '#,###,###.##', rounded to D decimal places, and returns the result as a string. If D is 0, the result has no decimal point or fractional part.

mysql> SELECT FORMAT(12332.123456, 4);

    -> '12,332.1235'

mysql> SELECT FORMAT(12332.1,4);

    -> '12,332.1000'

mysql> SELECT FORMAT(12332.2,0);

    -> '12,332'

Edit:

I was about to add that "the downside of using this method is that you cannot that number in your code", but apparently this is not a problem anymore, starting from PHP 5.3, thanks to the parse function of NumberFormatter class:

NumberFormatter::parse numfmt_parse

— Parse a number

Example

parse($num)."\n";
echo $fmt->parse($num, NumberFormatter::TYPE_INT32)."\n";
?>
