-------------------------------------
*Dev Design*
Add judgment: the type is a string, but it is a time format, then it will be
processed according to the time
> The query result is incorrect after converting the string type data in
> 'yyyy-mm-dd' format to timestamp type and querying with filter of this column

> The query result is incorrect after converting the string type data in
> 'yyyy-mm-dd' format to timestamp type and querying with filter of this column.
>
> Steps to reproduce:
> 1. Create a hive table, the field type is string, and insert data 2022-12-01
> {code:java}
> create table test(dt string);
> insert into test values('2022-12-01'); {code}
> 2. Use kylin loads the table and builds the model
> 3. Query as follows sql, result is empty
> select dt,cast(dt as timestamp) from TEST.TEST where cast(dt as
> timestamp)='2022-12-01 00:00:00.0'
