> Case for SqlAdvisorTest:
> {code:java}  @Ignore("It looks like s.count clashes with COUNT keyword, however the same SQL executes just fine")
>   @Test @WithLex(Lex.JAVA) public void testAdviceExpression() {
>     String sql;
>     sql = "select s.count+s.co^ from (select 1 count from emp) s";
>     assertComplete(sql, "COLUMN(count)\n", "co",
>         ImmutableMap.of("COLUMN(count)", "count"));
>   }
> {code}
> It is not clear why SQL fails to advise, however the same query works just fine via JDBC.
