How does Python's super() work with multiple inheritance?
...t have the attribute, then it will look at Second.
This situation becomes more complex when inheritance starts crossing paths (for example if First inherited from Second). Read the link above for more details, but, in a nutshell, Python will try to maintain the order in which each class appears on ...

Why use the INCLUDE clause when creating an index?

@gbn, would you mind explaining this sentence in more detail, and explain why it means that the include clause is not useful for sorting, etc: "The INCLUDE clause adds the data at the lowest/leaf level, rather than in the index tree. This makes the index smaller because it'...
