It is known that the number of rows in the two tables is the same. Except for circular assignment, is there any change Simpler and more direct approach

It should not. If it is listed, it is OK.

If it is added, you can clone the entire table and delete the columns.


Now it is to update and it is a column, the column itself does not hold data. So it can only loop.
