///     Appends SQL for inserting a row to the commands being built, via an INSERT followed by an optional SELECT to retrieve any
///     database-generated values.

Given that two operations may be inserted, isn't the plural correct?

The way I think the naming here works, we have a single insert operation (corresponding to a single ModificationCommand), implemented via two commands. We could also rename to AppendInsertAndSelectCommands. It's all maybe a bit subtle :)

In any case, AppendInsertAndSelectOperations is inconsistent with AppendUpdateAndSelectOperation and AppendDeleteAndSelectOperation (which don't have s), we should fix that one way or the other (can wait for the executive consistency officer as well).

Let there be consistency!
