mySQL cli is a fast and nice tool to manage your DBs. I suppose we'll never get rid of it because of it's extreme usefulness.
I bet you already know what it means to "slip your hands in the jam" (just an italianism, not to be taken too seriously), and end up searching for that darn query command, re-learn its syntax, copy-paste and repeat until you found that combination that simply works™…
Hopefully, some clever devs came to our help and invented GUIs (well, sort-of), like phpMyAdmin, (and plenty others too!).
These tools allow poor sysadmins, pwrusrs and the like, for an easier DB administration and a frustration-free INSERT query.
Basically, it's just a 200k, single-file phpMyAdmin alternative. You simply upload it to your "DB-powered-website", toggle some switches and you're good to mess-up your DB!
The author of this tool is this European czech guy called Jakub Vrána, who does seem to be knowing what he's up to.
