Hallo,

I want to perform a recursive query in vb.net (MSSQL Server as Database). I found out how to do it in mssql (e.g. here: MSSQL Recursive Hierarchial Query[^]
), but how can I call it in vb.net?
My table looks like this:

ID Parent Name
---- ---- ----
1 Null A
2 1 B
3 1 C
4 3 D
...

So how can I get the IDs of every child element of a certain element?

Thanks

C#

function get_id(int p_id)
{
   execut this line----
     -> "select id from table_name where parent="+p_id+"";

  it will return a result set
   in while loop access all its ids
  while(rs.next())
  {
     get_id(rs(0));// it is call to the parent function
  }
}

in this way we can get all child elements of a certain parent element
