Hi all,
I just changed connectby() to order siblings and return an additional
serial column.
Everything is working fine so far, but I think there could be a problem
due to the static definition of the serial variable.
I need the variable to be static, because the function itself is
recursive.
What will happen if 2 processes concurrently use the function ? will
they conflict ?
I guess, that if I set the variable to 1 at each beginning of the
function, it will conflict.
If I do _not_ reset the serial at each function call, that would lead to
an overflow sooner or later.
Any idea ?
