title: Simba Spark JDBC driver - DatabaseMetaData.getColumns() does not work
body: <p>I am trying to get metadata for a column in a table in Spark on Databricks. I am using the Simba JDBC driver for Spark (SimbaSparkJDBC42-2.6.16.1020.jar)</p>
  <pre><code>DatabaseMetaData metadata = conn.getMetaData();
        ResultSet resultSet = metadata.getColumns(&quot;SPARK&quot;, &quot;default&quot;, &quot;testtable&quot;, &quot;id&quot;);
        while (resultSet.next()) {
          String name = resultSet.getString(&quot;COLUMN_NAME&quot;);
          String type = resultSet.getString(&quot;TYPE_NAME&quot;);
          int size = resultSet.getInt(&quot;COLUMN_SIZE&quot;);
  
          System.out.println(&quot;Column name: [&quot; + name + &quot;]; type: [&quot; + type + &quot;]; size: [&quot; + size + &quot;]&quot;);
        }
  </code></pre>
  <p>I have 5 columns with the primary key being the column 'id' (bigint) and the rest of the column of datatype string. The code above gives an output when I replace the column name by 'null' (I can then see the all the columns details) and when I look for the column name pattern 'id' (primary key of my tables) but <strong>is empty for all the other column</strong> I test with... any help would be appreciated!</p>
