> Hi Team.
> We using Drill 1.18.
> There is a phenomenon that the count values of COL4452 are different in the
> execution results of the following queries.
> The only difference is that the positions of COL4452 and COL6408 have been
> changed.
> {code:java}
> 1.
> select COUNT(DISTINCT val2) COL4452, SUM(CAST(val11 as BIGINT)+CAST(val12 as
> BIGINT)) COL6408 from dfs.root.`/drill/data/*/log_15872_R_79_*.parquet` WHERE
> 1 = 1 and ( ( dir0 between '01' and '10' ) ) and ( LOG_DATE >= '2022-04-01
> 00:00:00.000000' and LOG_DATE <= '2022-04-30 23:59:59.000000');

> correct.
> I am having trouble understanding the cause of this phenomenon.
> Can anybody help me?Thanks in advance.
