Re: Index Not being used.
All fields are from the pos_ord_lines table. The ORD_Date where clause uses the pos_ord_headers table. When you think of the tables there is a header table that is order header containing ord_id, ord_date, ord_merch, ord_discount, ord_tax and then the pos_ord_lines can have multiple items on each order. The system has 4 GB of RAM. I have tried with and without the FORCE INDEX. With is returns 5,134,336 rows and without it doesn't use the index and returns 19,000,000 rows from header. Either way it times out after 600 seconds. This table is updated multiple times daily by various clients running end of day and transmitting this information. It isn't so much a data warehouse as I understand the definition.
