title: Wrap double quotes across native query parameter in Spring data jpa
body: <p>I have to run the following Oracle query using Spring Data JPA native queries.</p>
  
  <pre><code>create user "kshitij" identified by "qwert123"
  </code></pre>
  
  <p>I am trying this :</p>
  
  <pre><code>@Query(value="create user \"?1\" identified by \"qwert123\"",nativeQuery=true)
      void createUser(String userName);
  </code></pre>
  
  <p>However when I wrap ?1 by "" then it Hibernate stops treating ?1 as variable to be substituted by userName, instead as actual string. 
  How would I accomplish running the above mentioned Oracle query in spring data jpa?</p>
  
  <p>Alongwith create I would also like to check if user exists.</p>
  
  <p>Current not working approach : </p>
  
  <pre><code>@Query(value="select username from all_users where username = \"?1\"", nativeQuery=true)
  </code></pre>
