Select data from date range between two dates
As you can see, there are two ways to get things done:
- enlist all acceptable options
- exclude all wrong options
Obviously, second way is much more simple (only two cases against four).
Your SQL will look like:
SELECT * FROM Product_sales WHERE NOT (From_date > @RangeTill OR To_date < @RangeFrom)
SELECT * from Product_sales where(From_date BETWEEN '2013-01-03'AND '2013-01-09') OR (To_date BETWEEN '2013-01-03' AND '2013-01-09') OR (From_date <= '2013-01-03' AND To_date >= '2013-01-09')You have to cover all possibilities. From_Date or To_Date could be between your date range or the record dates could cover the whole range.
If one of From_date or To_date is between the dates, or From_date is less than start date and To_date is greater than the end date; then this row should be returned.
