title: Mock Stored procedures with Spring Boot and HSQLDB
body: <p>I am working on a Spring Boot project with HSQLDB as in-memory database for my tests. 
  The reason why I decided to use HSQLDB over h2 is that my datasource is quite old and contains a lot of queries with multiple OUT parameters that H2 cannot handle</p>
  
  <p>While I am able to run using JPA queries with multiple OUT parameters on HSQL, I need now to Mock some of the stored procedures. </p>
  
  <p>In H2 is possible as you can see for instance <a href="https://medium.com/@callkalpa/user-defined-functions-and-stored-procedures-with-h2-database-a1cbfa510559" rel="nofollow noreferrer">here</a>. Is it possible to mock stored procedures on HSQLDB? So far I could find only some really old articles (2011) and nothing in the HSQLDB documentation itself. </p>
