Today I was musing about how great \c is, and how it seems that many people are not aware of it, even though it’s in the banner of MySQL, and has been for a while.
So I decided to see what else I could find. I typed \h and found that a simple \W will show all warnings automatically after a query. That is great for the commandline interface! Now I just have to figure out if it’s possible to automatically do a \W (or “warnings”) whenever I log in with the commandline client.
