Smart admins have daily updated backups of the last 7 days and can always go back to their status quicklySmart admins will instead
RENAME TABLE old_table_name TO xx_old_table_name;and
ALTER TABLE table_name RENAME COLUMN old_col_name TO xx_old_col_name;and leave them there for a few days to ensure no impact or errors, before then coming back and removing them
Everyone does that as he likes it best, but a "smart admin" doesn't have to mention that separately either ...
And who wants to tell a developer what useful things he can build into his tool just because someone thinks "other users" are not able to use software correctly?
If I enter
rm -rf /*
