title: SQL splitting a word in separate characters
body: <p>I need to change an application and the first thing I need is to change a field in a database table. 
  In this table I now have 1 to 6 single characters, i.e. 'abcdef'
  I need to change this to '[a][b][c][d][e][f]'</p>
  
  <p>[edit]  It is meant to stay in the same field. So before field = 'abcdef'   and after field = '[a][b][c][d][e][f]'.</p>
  
  <p>What would be a good way to do this?</p>
  
  <p>rg.
