databases/p5-Iterator-DBI 0.02_1 FreeBSD

his module contains a function to return an iterator (see the Iterator module) that returns the rows of a database query, one at a time.

This is marginally more useful than simply calling prepare and execute, and then repeatedly calling fetchrow_hashref; since this one function bundles up the calls to all three of those DBI methods.

But the real usefulness of this interface is that it can be chained together with other Iterator functions. The "idb_rows" iterator has the same interface as any other interface, making it interchangeable with iterators of any other source (for example, files), and usable with the iterator manipulation functions in the Iterator::Util module.
