Hello everyone!
I have an interesting task related to the desktop, we have a table combined with certain attributes and with full names, full names are divided into columns (firstname, lastname, midname) and they need to be compared with other columns (firstname1, lastname1, midname1) it is necessary to output non-matching full names. I can't compare one table between columns, I need your help. Do you know how to implement this?
I will be very grateful for your help
