Interesting. If I were still working with Oracle, I'd love to see a sqlplus replacement. It has to be one of the most braindead CLIs ever, yet is too often instrumental to getting some actual work done with the shell et al.
Or just use usql.<p><pre><code> go get -u github.com/xo/usql
</code></pre>
Autocompletion is the only feature it doesn't have compared to these, and it's significantly easier to work with, and works with more databases. Autocompletion will be done early next year.
And the one database whose client needs [CURSOR UP] history and autocompletion, Oracle, isn't listed.<p>Vertica doesn't need an added value client: her client is already pretty good out of the box.
