> Some tests rely on the expression
> {{case when true then deptno else null end}}
> to obtain a nullable expression. However, the expression can be simplified to {{{}deptno{}}}, and deptno is a {{{}TINYINT NOT NULL{}}}. Replacing the expression with
> {{case when deptno>0 then deptno else null end}}
> ensures that the expression cannot be simplified.
