I dont ting riak can be used that way. Its not like MYSQL, where you can issue those kind of relational commands. At the best of my knowledge, at least from the command line interface you cannot do that.
My name is Wagner, and I'm really new at Riak.
I'm trying to do some testes, for my masters degree. But I don't know how to do it.
Its very simple, basically I have to test commands like "Select", "Create", "Insert"
I tried, using the root user\riak user\riak attach. As you can see in the attachments.
