We can build an insert statement easily, too.
my ($sql, @sql\_params) = INSERT INTO 'foo', \[ 'bar', \], VALUES \[ 1, \];
`INTO` takes a table, which it feeds to `INSERT`. The `INSERT` function likewise takes a list of table columns (in an array ref), followed by `VALUES`, which itself takes an arrayref of the data you're going to put into the columns. All the scalars in that arrayref are passed back in `@sql_params` and filled in as placeholders.
Inserting with a subselect is supported, which we will cover later.
