  Ok you DBA Gods this one has got me to that point that I just want to say F-it I cant do it I give up.

  I hope I can explain this well...

  I need to create a recursive query to supply the data to a TELERIK treeview. The problem is that the data I have to play with is not in an easy format to work with.

  I have three tables. WORK_ORDER, PART AND REQUIREMENT (Database is from Infor ERP VISUAL - ERP manufacturing Software)

  The WORK_ORDER table can have parts and the REQUIREMENT table can also have parts. Both connect to the same part table using the Part_id. A work order can have multiple requirements with many parts. Here is the view that gives me all the data I need.

  SELECT WORK_ORDER.BASE_ID, WORK_ORDER.PART_ID AS WO_PART_ID, PART_1.DESCRIPTION AS WO_DESCRIPTION, REQUIREMENT.PART_ID,

  PART.DESCRIPTION

  FROM WORK_ORDER INNER JOIN

  PART AS PART_1 ON WORK_ORDER.PART_ID = PART_1.ID INNER JOIN

  REQUIREMENT INNER JOIN

  PART ON REQUIREMENT.PART_ID = PART.ID ON WORK_ORDER.BASE_ID = REQUIREMENT.WORKORDER_BASE_ID

  WHERE (REQUIREMENT.STATUS = 'R')

  However, I want to Traverse this data so I can create a parent child relationship or change the above query to a recursive query. NOTE almost all parents are duplicated because they also can have multiple parts and requirements.

  BASE_ID WO_PART_ID WO_DESCRIPTION PART_ID DESCRIPTION

  0406030766 Truss Rod Gusset - tall 01034 Flat Bar 1/4 x 5 per inch

  0406130767 Truss Rod Gusset - short 01034 Flat Bar 1/4 x 5 per inch

  0410930420 Impeller 01037 Flat Bar 1/8 X 1 per inch

  0333728604 Gusset 01047 Round, 1/2 HR per inch

  0358228604 Gusset 01047 Round, 1/2 HR per inch
