title: How to read this qtstring in qsqlquery.exec
body: <p>I am learning qtsql but come across this qtstring in qtsql::query.exec()</p>
  
  <p>I never see this string before in C++. </p>
  
  <p>Can someone explain why there are some many quotation? And how to read this? Is this one string or five strings? If there are five strings, why there aren't any separators like a comma in between? Also query.exec is expecting a const &amp; QTstring. So if this is one string, is it same as "create table person (id integer primary key, firstname varchar(20), lastname varchar(30), age integer)"?</p>
  
  <pre><code>ret = query.exec("create table person "
                "(id integer primary key, "
                "firstname varchar(20), "
                "lastname varchar(30), "
                "age integer)");
  </code></pre>
  
  <p>Thanks in advance.</p>
  
  <hr>
  
  <p>It doesn't compile, as I get this error</p>

  <p>But it also doesn't look like an error, since both these two sites are referring to this syntax:</p>
