The order of the columns does not matter as you define the column order when
writing queries in your SELECT statement.
If you really want to accomplish this, you can create table with temporary
name with the desired column sequence, then insert the data from the
original table into the new table, drop the old table, and rename the new
table to the original table name (using sp_rename). Since you have IDENTITY
column you may have to use SET IDENTITY_INSERT to ON to preserve the column
values.
