Hi, [~nobigo] , ^ mean the error position.
In Calcite, [Alias in aggregate is not
allowed.|https://github.com/apache/calcite/blob/d1fe017e528230aaa10affb9111f62b08c50b186/core/src/test/java/org/apache/calcite/test/SqlValidatorTest.java#L5718]
But the old validated way is incorrect, I use a new validated way to avoid
misjudgment.

Hi, [~nobigo] , ^ mean the error position.
In Calcite, Alias in aggregate is not allowed[1]. But the old validated way is
incorrect, I use a new validated way to avoid misjudgment.

> We know that calcite can support HAVING alias by setting
> SqlConformanceEnum.LENIENT
> {code:java}
> sql("select count(empno) as e from emp having e > 10")
> .withConformance(lenient).ok(); {code}
> but when I add one aggregate function in HAVING clause, it will fail.
> {code:java}
> sql("select count(empno) as e from emp having ^e^ > 10 and count(empno) > 10
> ")
> .withConformance(lenient).fails("Column 'E' not found in any table");
> // I think it should be ok{code}
