Deleting duplicate rows from tables is one of the common task oracle developers come across. The data might get duplicated because of missing primary/unique key on the table or batch file getting loaded multiple times. Here I have tried to summarize different ways of deleting this duplicated data. Please note that this is not an extensive list of all available methods but the ones I was able to figure out. This should serve as a handy reference while at work.
