Обсуждение: Select into

Hi All,

Is it possible to insert into a table based on a select from another table?

The docs for SELECT INTO and like seem to imply you can only create a table
based on a select, not append to an existing table.

How do you do this?

I think you can use
INSERT INTO <table>(<cols>) SELECT ...

Sure, do INSERT INTO ... SELECT.

source-table [where ...]
