title: SQL split string (all possible combination)
body: <p>I would like to transform this string:<br>
  A1+A2+A3.B1+B2.C1<br>
  into<br>
  A1.B1.C1<br>
  A1.B2.C1<br>
  A2.B1.C1<br>
  A2.B2.C1<br>
  A3.B1.C1<br>
  A3.B2.C1<br></p>
  <p>How can I do that? (note that each dimension(= a group separate by .), could have x values, I mean it can be A1+A2.B1.C1 or A1+A2.B1+B2+B3+B4+B5.C1+C2)</p>
  <p>Thanks</p>
