a b
1 2009
2 2007
3 2006
4 2010
5 2011
How I will select all years that greater than 5 years ago from year today?
So it would be like 2013(year today) - 5 = 2008
a b
1 2009
4 2010
5 2011
I tried this:
select * from table1 where b > CURRENT_TIMESTAMP - 5
I use smallint as datatype of column b instead of date because I will only store the year. Is it safe to use small int for storing year?
您接近:
select * from table1 where b > YEAR(CURRENT_TIMESTAMP) - 5
select * from table1 where b > DATEADD(YEAR,-5,GETDATE())
应该也可以
