title: SQL join two tables without keys/relations
body: <p>I have two tables, one of them has weeks of year, and the second table has categories. I need to create a table that contains each week and each category, but there's no fields/keys that intersect in two tables:</p>
  
  <p>Table 1:</p>
  
  <pre><code>week1
  week2
  week3
  week4
  </code></pre>
  
  <p>Table 2:</p>
  
  <pre><code>Cat1
  Cat2
  </code></pre>
  
  <p>Resulting table:</p>
  
  <pre><code>week1 cat1
  week1 cat2
  week2 cat1
  week2 cat2
  ...
  week4 cat1
  week4 cat2
  </code></pre>
  
  <p>I'd like to do this without using many cursors/looping.</p>
