Regular Expression to Match All Comments in a T-SQL Script

In PHP, i'm using this code to uncomment SQL (this is the commented version -> x modifier) :

trim( preg_replace( '@
(([\'"]).*?[^\\\]\2) # $1 : Skip single & double quoted expressions
|(                   # $3 : Match comments
    (?:\#|--).*?$    # - Single line comment
    |                # - Multi line (nested) comments
     /\*             #   . comment open marker
        (?: [^/*]    #   . non comment-marker characters
            |/(?!\*) #   . not a comment open
            |\*(?!/) #   . not a comment close
            |(?R)    #   . recursive case
        )*           #   . repeat eventually
    \*\/             #   . comment close marker
)\s*                 # Trim after comments
|(?<=;)\s+           # Trim after semi-colon
@msx', '$1', $sql ) );

Short version:

trim( preg_replace( '@(([\'"]).*?[^\\\]\2)|((?:\#|--).*?$|/\*(?:[^/*]|/(?!\*)|\*(?!/)|(?R))*\*\/)\s*|(?<=;)\s+@ms', '$1', $sql ) );

This should work:

(--.*)|(((/\*)+?[\w\W]+?(\*/)+))
