      Sends SQL queries to an SQLite cloud database provided
      as a service at <a href="https://www.sqlitedb.com/" target="_blank">https://www.sqlitedb.com/</a>
  </p>
  <p>
      To use this node first register for an account at <a href="https://www.sqlitedb.com/" target="_blank">https://www.sqlitedb.com/</a>
      and create a database. Get the provided API URL and API KEY and add to this
      node configurations to be able to access the cloud database.
  </p>
  <p>
      An online admin panel is provided with each cloud database.
      It allows to fully manage the database via a web browser and allows
      the following actions to be completed conveniently via a graphical
      user interface:
      <br />
      <b>TABLES</b><br />
      - alter tables<br />
      - create tables<br />
      - drop tables<br />
      - export tables<br />
      - truncate tables<br />
      <br />
      <b>RECORDS</b><br />
      - delete records<br />
      - insert records<br />
      - select/read records<br />
      - update records<br />
      - view/search records<br />
  </p>
  <p>
      The node provides two methods for providing the SQL code for the query:
      <br />
      - <i>fixed</i> - convenient for permanent SQL statements. The SQL is entered directly in the node configurator.
      <br />
      - <i>msg.topic</i> - for dynamic statements. The SQL is composed via a functions node and appended to the message's topic attribute before sent onwards.
  </p>
  <p>
      Using any SQL query, the result is returned in <code>msg.payload</code>.
      After submitting the query a response message in the payload will be
      returned in the following format:
      <br />
      - Success response<br />
      <code>{"status":"success","message":"Message text","data":[]}</code>
      - Success response<br />
      <code>{"status":"error","message":"Message text"}</code>
      <br />
      Checking the "status" attribute allows to find out if the SQL query
      was executed successfully.
      <br />
      Checking the "message" attribute allows to find out more information about the query's result.
      <br />
      The "data" attribute contains the records returned by SELECT type queries.
  </p>
