> In this JIRA, will create some sub-task for add specific scalar function, such as mathematical-function {{LOG}}, date-functions
>  {{DATEADD}},string-functions {{LPAD}}, etc. 
> I think is good way to let SQL work, and then add TableAPI to supported. So I suggest one scalar function create two sub-task, one is for SQL. another for TableAPI.
> *Note:*
> Every scalar function should add TableAPI doc in  {{./docs/dev/table/tableApi.md#built-in-functions}}. 
> Add SQL doc in {{./docs/dev/table/sql.md#built-in-functions}}.
> Welcome anybody to add the sub-task about standard database scalar function.
