diff between tables
- by www.yegorov-p.ru
I have two tables, with the same structure, for example: table "first' with columns 'a','b','c' and table 'second' with the same columns. How to find difference betweet those two tables?
Of course, I can make some script on python, that will make set(a)-set(b), but I think there is some way to do it in mysql.
