I've got a table that holds line items for items that a customer is paying. There is a unique field (EntryNumber) and a field that ties all like items together (ItemNumber). If I query it I may get something like this:
EntryNumber,ItemNumber,Price
1,myitem,1.00
2,myitem,1.00
3,myitem,1.00
4,myitem,0.00
5,myitem,1.00
6,myitem,2.00
The goal would be a query that removes duplicate prices that are sequential. In other words entrynumber 2 and 3 removed, all else remaining so you would get entrynumbers 1,4,5,6 returned. Note that not all the price duplicates were removed, 1 and 5 remain in the result because they are separated by 4 having a price of 0.
