Yes Rbase does not support recursion. Wish it did for BOMs as well. Dan Goldberg
From: [email protected] [mailto:[email protected]] On Behalf Of Stuart Hellman Sent: Tuesday, August 9, 2016 1:07 PM To: [email protected] Subject: [RBASE-L] - A recursive query For a DB Tree View, I’m trying to show a portion of the tree. Starting at a selected node, I want to show all of the sub nodes underneath the selected one and all the sub nodes for those nodes. An example would be a bill of materials; starting with a main part what are the subassemblies of that part and the subassemblies of those parts and so on. I would like to look at the complete explosion for 1 subassembly. Right now I build a bunch of views that join from the previous one and then append them all together in a temp table. I’ve done some searching on the internet and found info on a Common Table Expression (CTE), but it doesn’t look like RBase supports that SQL construct. Tried editing a view in RBase using another example, but can’t change the join code. Here is the code I’m trying to implement: SELECT T1.NodeID, T1.NodeText, T1.NodeColumnName, T1.NodeParentID + FROM TreeList T1 INNER JOIN TreeList S ON S.NodeID=T1.NodeParentID + WHERE S.NodeParentID in (SELECT NodeID FROM TreeList + WHERE NodeText = ’XXXXXX’) Tried changing the 1st WHERE to “WHERE EXISTS (SELECT…” and “WHERE IN (SELECT…”; neither worked (got error code 2043). Any and all advice would be appreciated.
