I connect to mysql from my Linux shell. Every now and then I run a SELECT query that is too big. It prints and prints and I already know this is not what I meant. I would like to stop the query.

Hitting Ctrl+C (a couple of times) kills mysql completely and takes me back to shell, so I have to reconnect.  

Is it possible to stop a query without killing mysql itself?


Question: Long rest regains half hit dice - round up or down?
Answer: Fortunately the answer is quite simple. From the Basic Rules (still applies in PHB):


  Round Down There's one more general rule you need to know at the outset. Whenever you divide a number in the game, round down if you
  end up with a fraction, even if the fraction is one-half or greater.
  ~ Basic Rules, p. 4


This should apply in all cases, except where it logically should not. The case you mention here would be a good example. Remember that it is very hard to make RAW consistent and synchronized at all times when it spans hundreds of pages. A bit of interpretation is often necessary.
