You can use computed columns in a select statement inside an insert statement.
For example, imagine that a table named tmp contains some new rows for the titles table, which contains out-of-date data—the price figures need to be doubled. A statement to increase the prices and insert the tmp rows into titles looks like:
insert titles select title_id, title, type, pub_id, price*2, advance, total_sales, notes, pubdate, contract from tmp
You cannot use the select * syntax when you perform computations on a column; each column must be named individually in the select list.
