each( $callback )

Iterate over the collection. for each record, $callback is called with the record passed in as its first argument.

insert(fiele_name1 => $value1, fiele_name2 => $value2, ...)

Insert a record to the table that this collection is referring to.

    db("posts")->insert(subject => "OHAI", body => "Nice to see you");

Is essentially doing this SQL:

    INSTER INTO posts (subject, body) VALUES ("OHAI", "Nice to see you");

Since this operation cannot be lazy, this SQL statement is executed right away.

Note that this only works for simple query. Complex selectors
