title: mapping SKUs on MySQL
body: <p>I have a set of SKUs(stockkeeping unit) for various items that I need to map to their indexes;
  example:</p>
  
  <pre><code>| __SKU_ID__|   __Item_Name__   |   __Price__  |
  
  |ST1200     |SwissCheese        |   $3.25      |
  </code></pre>
  
  <p>the ID is composed of 3 sets of unique identifiers containing 2 characters each, which would otherwise look like this: [ST],[12],[00]</p>
  
  <p>but considering theres no <strong>arrays</strong> in mysql, I cant find away around it. is there an alternative to array or another way i can do this?</p>
