id is key
insert into test select t1.id,@variable := t1.col from test t1 on duplicate key update col = col + @variable
insert into test t select t1.id,t1.col from test t1 on duplicate key update t.col = t.col + t1.col

Yes, I got that, too.
But here's a sneaky way around it:
Code:CREATE VIEW testview AS SELECT id, col AS viewcol FROM test; INSERT INTO test SELECT id, viewcol FROM testview ON DUPLICATE KEY UPDATE col = col + viewcol;
Be yourself. No one else is as qualified.
