> When casts are added in {{{}SqlValidator{}}}, they are not part of the select
> if the configuration option {{identifierExpansion}} is false. This will cause
> the following issue
> {code:java}
> SELECT distinct sum(deptno + '1') FROM dept ORDER BY 1
> {code}
> will lead to:
> {code:java}
> From line 1, column 21 to line 1, column 54: Expression 'SUM(`DEPT`.`DEPTNO`
> + CAST('1' AS INTEGER))' is not in the select clause
> org.apache.calcite.runtime.CalciteContextException: From line 1, column 21 to
> line 1, column 54: Expression 'SUM(`DEPT`.`DEPTNO` + CAST('1' AS INTEGER))'
> is not in the select clause

> {code}
> The issue is that the code in{{ AggChecker}} will search for the expanded
> node (with the CAST) in the select list, but the select list contains only
> the unexpanded node.
> This can be solved through setting{{ identifierExpansion }}to true, but I
> don't think it should be related, as it's not an identifier expansion here.
