> Invalid code is generated for negative of byte and short values. The reason is that, in Java, if b is a value of type {{byte}}, then {{-b}} has type {{int}}; similarly if {{b}} has type {{short}}. The code generator needs to accommodate for this.
> The query {code}select -deptno from dept{code} demonstrates the problem, since {{deptno}} has SQL type {{TINYINT}}.
