use of –i-am-a-dummy and --safe-updates flag in MySql For beginners, a useful startup option is --safe-updates (or --i-am-a-dummy, which has the same effect). It is helpful for cases when you might have issued a DELETE FROM statement but forgotten the WHERE clause.Normally, such a statement deletes all rows from the table.
