That's what it does.

What makes you think it can't?

Perrin,
I can't specify all of the columns in a Set statement in the
OnDuplicate clause because I don't know what the column names are and there
could be 100 columns. I'd like to use something like:
insert into Table2 select * from table1 on duplicate key update;
but this gives me a syntax error.
Error Code : 1064
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near '' at line 1
So it is looking for an Update expression. I'd like it to update all the
columns in the Select statement to the row with the matching key. After
all, this is what the statement was trying to do in the first place. I
don't see why I have to explicitly specify all of the value assignments in
the On Duplicate phrase over again.
