| Ryan writes "I’m trying to write a select statement that will show me all my current orders and order lines. I want it to show in detail the qty ordered, qty already shipped, and qty on hand. I also want it to calculate the total qty to make based on ((qty ordered – qty shipped) – qty on hand).I’m able to get the total to make for each order but I need to update my qty on hand as I use it up, so other orders for the same item do not calculate qty to make based on inventory already being used. My question is can I write in a select statement a nested update to update my current inventory levels. I have put all my inventories in a temp table so I’m not updating actual inventories levels. This is used as a production reference.INSERT INTO ## ProdToMakeSELECT co.co_num, coitem.co_line, coitem.due_date, coitem.item, coitem.qty_ordered, coitem.qty_shipped,(SELECT 'qty_on_make' = CASE WHEN ((coitem.qty_ordered - coitem.qty_shipped) - ##ItemLoc.qty_on_hand) = 0 THEN 0 WHEN ((coitem.qty_ordered - coitem.qty_shipped) - ##ItemLoc.qty_on_hand) > 0 THEN ((coitem.qty_ordered - coitem.qty_shipped) - ##ItemLoc.qty_on_hand) WHEN ((coitem.qty_ordered - coitem.qty_shipped) - ##ItemLoc.qty_on_hand) < 0 THEN 0 ENDFROM ## ItemLoc WHERE ##ItemLoc.item = coitem.item) AS qty_on_makeFROM co INNER JOIN custaddr ON co.cust_num = custaddr.cust_num INNER JOIN coitem ON co.co_num = coitem.co_num INNER JOIN job ON item.job = job.job AND item.suffix = job.suffixWHERE co.stat = 'O' AND custaddr.cust_seq = 0 AND (coitem.stat = 'O' OR coitem.stat = 'P') " |
