Greetings! I messed up! Nothing new in my life. :-) So, I inserted the wrong data in two columns. I know how to fix the problem with a small program, but I was wondering if there was a quick SQL call that I could do to fix the problem. The real problem is that I have a table called t and I have inserted the data that should have gone to column c3 on c4. And I also inserted the data that should have gone to c4 on c3. The desire is to exchange the data found on c3->c4 and the data found on c4->c3. There are two constraints: ProjID and InsertDate. The table definition is thus, ``` CREATE TABLE t ( ProjID, c1, c2, c3, c4, c5, InsertDate, PRIMARY KEY (ProjID,InsertDate) ); ``` Thoughts? thanks. josé
