Not a 7.0 bug, but a 6.5 bug --- it shouldn't have accepted that.
The correct SQL-approved way to do this sort of thing is
insert into accountloginrec
select 1,'test','test','test',NOW(),NOW()+30,Max(eshopcode)+1,null
from accountloginrec;
A values() expression is a standalone row-value constructor; it can't
legitimately contain any references to the insert destination table.
In fact the way INSERT is supposed to work is that it's processed as
INSERT INTO dest_table <something>
where the <something> is a row-value-yielding expression that would
have the same meaning whether it appeared in INSERT or not. 6.5 was
in error to accept free variables in the <something> as references
to the insert's destination table.
The INSERT...SELECT way works in 6.5 too, btw.
