Re: [MS_AccessPros] Summing from a hierarchy

 

Adam-


It's not clear what you're trying to do.

Yes, you can change the Record Source of a Form on the fly by assigning the appropriate SQL to the RecordSource property.

Repost. I'm looking for help in summing from children, grandchildren, etc., in a hierarchical relationship. See original post below.


I know how to create a recordset with this data, but I don't know how to have a form's recordsource be based on a recordset created at that time. I suppose I could make a table each time, but that seems inefficient. Is that how I should go? Is there another way?

I have clients set up in a hierarchical relationship. I want to be able to move (on a form) up and down the tree levels showing totals at each node for all the children, grandchildren, etc., under that node.


The key tables and fields (not all fields listed, just enough to explain, I hope) I have (so far) are:


tblClients:

  ClientID (auto)

  ClientName (text)

  ParentID (long)


tblAccounts (a client may have multiple accts)

  AcctNo (text, alphanumeric)

  AcctName

  ProductType (text)


tblParents

  ParentID (auto)

  ParentName (text)

  Parent (long, ParentID of this parent, if there is one)

  SalesRep


tblRevenue

  AcctNo (text)

  Revenue (currency)


I know how to sum from one level below, but not sure how to get beyond that.


Thanks
