Title

    [D] order -- Reorder variables in dataset


Syntax

        order varlist [, options]

    options           description
    ---------------------------------------------------------------------------------------------------------------------------------------------------
    first             move varlist to beginning of dataset; the default
    last              move varlist to end of dataset
    before(varname)   move varlist before varname
    after(varname)    move varlist after varname
    alphabetic        alphabetize varlist and move it to beginning of dataset
    sequential        alphabetize varlist keeping numbers sequential and move it to beginning of dataset
    ---------------------------------------------------------------------------------------------------------------------------------------------------


Menu

    Data > Data utilities > Change order of variables


Description

    order relocates varlist to a position depending on which option you specify.  If no option is specified, order relocates varlist to the beginning
    of the dataset in the order in which the variables are specified.


Options

    first shifts varlist to the beginning of the dataset.  This is the default.

    last shifts varlist to the end of the dataset.

    before(varname) shifts varlist before varname.

    after(varname) shifts varlist after varname.

    alphabetic alphabetizes varlist and moves it to the beginning of the dataset.  For example, here is a varlist in alphabetic order:  a x7 x70 x8 x80
        z.  If combined with another option, alphabetic just alphabetizes varlist, and the movement of varlist is controlled by the other option.

    sequential alphabetizes varlist, keeping variables with the same ordered letters but with differing appended numbers in sequential order.  varlist
        is moved to the beginning of the dataset.  For example, here is a varlist in sequential order: a x7 x8 x70 x80 z.


Examples

    Setup
        . webuse auto4

    Describe the dataset
        . describe

    Move make and mpg to the beginning of the dataset
        . order make mpg

    Describe the dataset
        . describe

    Make length be the last variable in the dataset
        . order length, last

    Describe the dataset
        . describe

    Make weight be the third variable in the dataset
        . order weight, before(price)

    Describe the dataset
        . describe

    Alphabetize the variables
        . order _all, alphabetic

    Describe the dataset
        . describe

楼上说的是stata11的 order吧，好像10的版本没有option吧，不过10的可以用下面的order或是move 两个命令
Move specified variables to front of dataset
order varlist
Move one variable to specified position
move varname1 varname2

there is an old command for stata 9 and prior:
ssc install placevars

yes ,use the command "move"
sample: move var1 var2
