Is there a better/more concise way to write this query?

Question

I am writing a query for a stock database and I am looking for the top 5 stocks in terms of price increase for each year (2010 - 2016). Right now I am writing it like this:

(
   SELECT Ticker, Year, MAX(High - Low)
   FROM Stocks
   WHERE Year = 2010
   GROUP BY Ticker
   ORDER BY MAX(High - Low) DESC
   LIMIT 5
)
UNION ALL
(
   SELECT Ticker, Year, MAX(High - Low)
   FROM Stocks
   WHERE Year = 2011
   GROUP BY Ticker
   ORDER BY MAX(High - Low) DESC
   LIMIT 5
)
UNION ALL

and repeating that for each year until 2016.

The create table statement is:

CREATE TABLE Stocks (
    Year   DATE
    Ticker VARCHAR(8),
    High   FLOAT,
    Low    FLOAT,
    Volume FLOAT,
    PRIMARY KEY(Ticker, Year)
);

And the resulting data set would be something like this:

Year    Ticker    MAX(High - Low)
---------------------------------
2010    GOOG      100
2010    FB        99
2010    AAPL      98
2010    NFLX      97
2010    ABCD      96
2011    FB        120
2011    ABCD      112
etc... (Top 5 in terms of high-low per year)

Is there a better and more concise way to write this?

Answer 1

You can try IN statement.

SELECT Ticker, Year, MAX(High - Low)
FROM Stocks
WHERE Year IN ('2010', '2011', '2012', '2013', '2014', '2015', '2016')
GROUP BY Ticker
ORDER BY MAX(High - Low) DESC

Hope this helps.
