I accidentally deleted some huge number of rows from a table…
How can I roll it back?
I executed the query using PuTTY.
I’ll be grateful if any of you can guide me safely out of this…

If you didn’t commit the transaction yet, try
rollback. If you have already committed the transaction (by manually execitingcommitor by exiting the command line client or when the optionautocommitis1which is the default), you must restore the data from your last backup.To prevent things like that in the future, use
SET autocommit=0before any dangerous work. Any changes will be kept inside of your current transaction until you commit them. See https://dev.mysql.com/doc/refman/8.0/en/innodb-autocommit-commit-rollback.html for details
