title: How can I count all the NULL values in all columns in a sqllite table?
body: <p>I don't want to write a large query statement like </p>
  
  <pre><code>SELECT SUM(CASE WHEN column1 IS NULL THEN 1 ELSE 0),
         SUM(CASE WHEN column2 IS NULL THEN 1 ELSE 0),
         SUM(CASE WHEN column2 IS NULL THEN 1 ELSE 0),
  ....
  FROM Table
  </code></pre>
  
  <p>Because there are almost 200 columns.
  And the result should show the amount of NULL distinct by column.</p>
