Hi - Im hoping there is a howto someone can point me to for what is probably a common issue.I have a list of customers in a parent table.I have a list of orders in a child table, along with particulars relating to each order such as colour etc.I would like to be able to restart the numbering of orders for each customer, so I can quickly view how many orders have been ordered by each customer? At the moment, the order list has a primary key that increments for each order, no matter which customer.I hope this makes sense and Im really grateful for any help.ThanksFrank |

you can put a logic using ROW_NUMBER for filling OrderSeqNoget maxorderno for customer anduse logic likeMaxOrderSeqNo + ROW_NUMBER() OVER (PARTITION BY CustomerID ORDER BY OrderID)------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |
