What I want to do is to match the content of table1 with the content of table2. If the content of table2 exists in table1, it is deleted in table1, and if it does not exist, the content of table2 is inserted into table1.
So, is there any content which exists in table2 which is also in table1? I don't think so, right? or I might not have understood the issue... can you share the expected output based on the two tables provided?
