Syntax example of an Inset statement where it is selecting values from another table

All

I am wondering if anyone has an example of an Inset statement where it is 
selecting values from another table. 

So for example in sql or a stored proc it would look like this

        Insert into table a (column1,
                         column2,
                         column3,
                         column4
        select( column1,
                        column2,
                column3
                column4
        from table b 

But am not sure of the syntax when using DBI
I know when I want to insert a row I can do this, but am not sure of the 
syntax when I want to grab a bunch of rows from one table and insert them 
into another.

$sth=$dbh->prepare(qq{INSERT INTO table b(column1, column2, column3, column4) VALUES (?, ?, ?, ?)}); 

I guess one solution is to loop thru the rows that I get returned via a 
select statement but that seems like a waste of processing time

Any help would be appreciated
