[thelist] SQL partial string replace

UPDATE yourtable
  SET emailcolumn
     = REPLACE(emailcolumn,'asd.k12.ak.us','asdk12.org')
         WHERE emailcolumn like '%asd.k12.ak.us%'

the WHERE condition will choose the rows to update -- without it, you will
update every row in the table (most of them with the same value they were)
