What do you mean by this? Do you mean instead of having the opDispatch
in the Connection class, we'd have it in a separate struct / template /
other magic? This would allow us to utilize this method for other
sources of data, such as XML.
Something like that. Take advantage of opDispatch in a more ORM like
interface. Which also hides the connection and executing of raw SQL.
On the other hand though, this doesn't add a whole lot. Let's say we had
this code:
auto rows = db.execute("SELECT score, a.user FROM users a JOIN scores b
on a.user = b.user");
foreach (row; rows) {
writeln(to!int(row["score"]));
}
I think that the above code would sit in a middle layer between the
lower level of the database driver and a higher level of an ORM like
interface. See my reply to one of Andrei's posts.
