While debugging SQL statements, if I accidentally execute a query in using the mysql command line that outputs at lot of results (even if the query itself executes in reasonable time), the only way I know of to stop the endless stream of output is CTRL-C.
Unfortunately this puts me back in the shell, forcing me to login and select the database again.
To avoid this I've started running mysql with the --sigint-ignore option so that CTRL-C is ignored.
Now I'd like a way to interrupt the output of those long queries.
Is there a keyboard shortcut that will do this?
You can use
--pager to have your output passed to a pager such as
less which will give you control over the output. Not just killing it, but also paging, searching and even storing the output better than your terminal window gives you.
There's also the
-U switch aka
--i-am-a-dummy which protects you from clauseless
deletes and also auto limits selects to 1000 (modifyable with select_limit).
All of this can be set by default in
[mysql] pager safe-updates
