[jira] [Comment Edited] (CALCITE-5039) View:Timestamp cannot query Data:Long in GMT+8 TimeZone Env

---------------------------------------------------------------
I may understand the complexities of timezones.
In a nutshell ,in "GMT+8" TimeZone env,i still can not query the data which it's physical datatype is long(mysql),while it's logical datatype is Timestamp(calcite) using a sql like "select * from table where ts='{*}2022-03-14 00:00:00{*}' limit 10" gracefully

> Key: CALCITE-5039
> URL: https://issues.apache.org/jira/browse/CALCITE-5039
> Project: Calcite
> Issue Type: Improvement
> Components: core, jdbc-driver
> Affects Versions: 1.29.0, 1.30.0
> Reporter: itxiangkui
> Priority: Major
> Labels: TimeZone, Timestamp
>
> When I have a row like :
> |ts:TimeStamp|channel:String|pv:Long|
> |1647187200000|ios|10|
>
> while 1647187200000 is a timestamp in TimeZone of "GMT+8",the datetime is "2022-03-14 00:00:00"
> but you can not query the data using a sql like :
> ```sql
> select * from table where ts='2022-03-14 00:00:00';
> select * from table where ts<'2022-03-14 00:00:01' and ts>'2022-03-13 23:59:59' and channel='ios';
> ```
> it is like the jdbc-fether will filter the data when match the timestampString,while the timestamp String looks like '2022-03-13 16:00:00' or '2022-03-14 08:00:00'
