------------------------------------
[~lemonjing] For adding new functions to SQL, it would be helpful to list other
databases which supports it, e.g.,
Oracle/MSSQL/Mysql/PosgrelSQL/Spark/Hive/Calcite. This would make us easier to
understand the issue, and decide whether we should add them, and how it should
work.
> [Bitwise Functions] Add BIT_AND, BIT_OR functions supported in Table API and
> SQL
