anchor.diff:  
   Nested transactions are supported if your database supports them:
   
  -[source,java]
  --------------------------------------------------------------------------------------------------------
  -db.withTransaction(Propagation.NESTED, new TransactionCallback<Result>() {
  -    ...
  -});
  --------------------------------------------------------------------------------------------------------
  +[source,java,indent=0]
  +----
  +        db.withTransaction(Propagation.NESTED, new TransactionCallback<Result>() {
  +            ...
  +        });
  +----
   
   Miscellaneous features
   ----------------------
  
positive.code: or {jdkJavadocBase}java/io/Reader.html[Reader] to query. Similarly you can read them by asking back for {jdkJavadocBase}java/io/InputStream.html[InputStream]
  or {jdkJavadocBase}java/io/Reader.html[Reader].
  
  [source,java]
  -------------------------------------------------------------------------------------------------------
  try (InputStream in = new FileInputStream(name)) {
      db.update("insert into my_file (name, contents) values (?,?)", name, in);
  }
  
  try (InputStream in = db.findUnique(InputStream.class,
                          "select contents from my_file where name=?", name)) {
      ...
  }
  -------------------------------------------------------------------------------------------------------
  
  WARNING: Note that the returned {jdkJavadocBase}java/io/InputStream.html[InputStream] or
  {jdkJavadocBase}java/io/Reader.html[Reader] is only valid for the duration of the active transaction.
  
negative.code: 
  Normal updates are straightforward, since we don't need to do much work to map the results:
  
  [source,java,indent=0]
  ----
          int modifiedRows = db.update("delete from user where id=?", 42);
  ----
  
  If you plan to return stuff from updates, they are queries as far as Dalesbred is concerned:
  
  [source,java,indent=0]
  ----
          int id = db.findUniqueInt("insert into department (name) values ('foo') returning id");
  ----
