------------------------------------
Summary: Invalid code generated for negative of byte and short
values
Key: CALCITE-2180
URL: https://issues.apache.org/jira/browse/CALCITE-2180
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
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}}.
