Hi, how looks like your table relation about nodes? Is this plain text like ‘1.2.1’ or you have structural relation like PARENT_ID?

Each tree-node is a record in the table and has a primary-key. 1 1.1 1.1.1 1.1.2 1.2 1.2.1 1.2.2 2 2.2 2.2.1 3 3.1 3.1.1 Now I have a dataset which suspends only the green tree-nodes. I need a SQL which suspends the complete tree-path for each green cell 1 1.1 1.1.2 1.2 1.2.2 3 3.1 How can this be done??? TIA, Sepp
