Hi
Excuse me. I can’t speak English well.

I have 2 tables in my database.

Master_table has these fields : product_name, receive_date, price.

Detail table (daily information) has these fields : product_name, sell_date.

I wants to get a report of products that have been sold.
Since the price of a product is different in some days, the SQL command must use related record in Master_table which the date in master table be related to date in detail table.

I can do this in ACCESS by use of word “first”, but in SQL Server I can’t.

How is it possible?

Thanks very much

Solution 3

This should give you the price of the products on their sell date.

SQL

SELECT D.product_name,
       D.sell_date,
       (SELECT TOP 1 M.price
        FROM Master_table M
        WHERE M.product_name = D.Product_name AND M.receive_date >= D.sell_date
        ORDER BY M.receive_date DESC)
FROM Detail_table D
