selecting max and min year

[Eugene Anthony]

I have a table that has a DateTime column which uses a DataTime
datatype. How do I retrieve the minimum and maximum year using ms sql?

select max(datepart(yy, myColumn)) maxYear,
min(datepart(yy, myColumn)) minYear
from myTable

SELECT DATEPART(yy, MAX (foo_date)) AS max_year,
DATEPART(yy, MIN (foo_date)) AS min_year
FROM Foobar;

It is important not to put the DATEPART() inside the aggregate
functions. It is easy to find the min and max on a column via indexes
or statistics tables. Once you put a funciton inside an aggregate
function, you cannot use these tools and have to do a table scan.
