>
> When the user wants to derive one or more columns from the existing columns 
> and the
> existing columns are all needed, the user needs to spell all the columns they 
> need in the SQL.
> This will be very troublesome and time-consuming when we have dozens or 
> hundreds of columns. we can save trouble by using a wildcard in the SQL to 
> represent all the columns.
> that means if we have "id", "name", "age", "ts" these four columns already 
> and we want to add a new column driver from ts, we can use
> "select *, FROM_UNIXTIME(ts / 1000, 'yyyyMMdd') as dt from table_name"
> to represent
> "select id, name, age, ts, FROM_UNIXTIME(ts / 1000, 'yyyyMMdd') as dt from 
> table_name"
