Question

I always only need the most recent 10 years of data from the result set. The years will always have multiple records, so I can not pull only the first 10 records. How can I: SELECT Set 1, SELECT Set 2… through set 10 and only display those 10 years of data without pulling prior years?

Year    Quarter    Quarterly_yield
2012    1         8.41
2012    2        -0.71
2011    3         0.03
2011    4         3.43

Answer 1

You can do this this way:

SELECT * FROM table WHERE year IN 
                     (SELECT year FROM table ORDER BY year DESC LIMIT 10); 

This query can explained like this:

1. Inner query – select last 10 years from table
2. Outer query – select all columns from table where year in inner query result
