Thanks! My mistake, my 1st post wasn't clear. There is no WHERE clause at
UPDATE statement level, the line is echo by SQL*Plus to show what cause the
error...
However, we agree on the part of the statement that cause the error! But I
don't undestand why I can't use inline-view the same way I would use table
in a correlated-subquery ??
Thanks Alex.
