update from Backup table
I have 2 tables. Table1(Id,ColA,ColB,ColC) and TableBackup(Id,ColA,ColB,C
Table2 has the same columns as Table1.
I would like to update ColA and ColB in Table1 with ColA and ColB from TableBackup. The Id is the same in both tables.
How is best to do this?

oops, use "TableBackup" instead of "Table2" in the join clause
