Can DISTINCT be used on only one field in a query?
How do you do a DISTINCT on one field in the select clause and just include other fields in the select clause, not making them distinct?
For example:
SELECT DISTINCT IndivOrders.DATE_INVC, IndivOrders.ID_ORD, IndivOrders.ID_SHIP, IndivOrders.ID_CUST_SOLDTO, IndivOrders.ID_PO_CUST, IndivOrders.TYPE_ORD_CP, IndivOrders.SEQ_SHIPTO, IndivOrders.ID_CUST_BILLTO, IndivOrders.NAME_ORD_BY INTO DistinctIndivOrders FROM IndivOrdersI just want Date_Invc to be distinct. I do not want the others to be distinct. If I use a group by, I get an error because the other information in the select clause is not in the aggregatte.
Not possible. You have to query out all of the distinct values in one query and then take these results and reuse them to pick up the additional data.
