Are both of these valid in an update query ?
1st
PHP Code:
    UPDATE users SET name='test' WHERE (uid='1'
2nd
PHP Code:
    UPDATE users SET (user_idarmy_idVALUES (1,2), (1,3), (1,4
because I'm getting error on the second. So I'm asking here so I dont need to sit and try find an error when its not possible to use at all

thanks for your time
