Hi all

Previously Svein had kindly provided me with a CTE that will self join
my Accounts master table in a tree. In itself it is working fine. Now
the user wants to order the placement of the records a per their wish
and not the natural order the records were originally created in. To
this end I have added an iSrNo field that contains the order defined by
the user. So all records at the same iLevel within a branch of a tree
can have an iSrNo specified and they sort themselves and their children
accordingly.

Below is the adapted CTE that was provided to me before with the new
iSrNo field added. I have tried a few ORDER BY myself but that ruined
the tree compeltely.

If someone would kindly suggest a way for me to getting the tree as per
users iSrNo (for that iLevel) it would be great.

Please advise.

Kind regards
Bhavbhuti
