Hi Martin
Your sample/tree2 is an excellent project to manage tree in a db context.
I managed tree with recursive sql but now I will change to nested.
There is one thing that can make it better, I suppose :
There is always the ( + ) at left of the node even if this one is

I read with interest the articles you sent me. Particularly :

I filled the tree.fdb with the data of the example that the author gives. I
used 'flamerobin' as editor of database. I executed the tree.prj but the tree

Maximum 30 records in tree? Then a tmsesqlquery
The database is dynamic but the tree is not auto expanded. It is expanded
step by step, when dataset record changes ( after scroll). Its about maximum
30. What method do you suggest ? find is not possible may be locate , is it
applicable in recursive procedure ?

I think we can do more with recursive query like:
with recursive CTE (nKey,caption ,nkeyp) AS (
select id,name,pid FROM persons WHERE pid=:n
union all
select id,name,pid from persons
join CTE t
on t.nKey= persons.pid)
select * from cte ;
this sql statement is inserted to tsqlresu

There one uses the functions in the server with queries and SQL statements.

You suggest to use tsqlresult but in this case we can not set primary key
even less use find ( nkey, ) ?

In the msuniverse there are examples but with a known numbers of nodes.
{
with tmynode(treeedit[0]) do begin
caption:= 'A';
add(3,tmynode);
items[0].caption:= 'A0';
items[1].caption:= 'A1';
items[2].caption:= 'A2';
