merge two query
- 5 years ago
Ideally it would be to have Query2 (historical data) for each date. Query1 (portfolio) may not be on each date, but for each date where it occurs, the same combination (stock, date) should be available in history table. This way all data will be matched.
And in this case you might use Inner Join to return only matched data. If you need all data (even without join) you can use Outer join, but then there might be lots of nulls.
hello

But i can't manage to have my which i only have couple point of data to match the day of the second query where i have all date of a year.
