Let's say I have some the following table schema:
year|val1|val2
I want to get all the val1
and val2
columns that has all values of year
column. I suspect I need grouping here, but I can't imagine how.
Let's say we have set of years from query: SELECT DISTINCT YEAR FROM table
. Let's say it returned 2000,2001. So If I have to rows as 2000|1|2
and 2001|1|2
then the query should return single row 1|2

Not sure about your question. But I think you need all the values of val1 and val2 which are there for all the valid values of years.If that's the case then you have to do inner join with the table something like this
select @yearcnt = count(distinct year) from table
or select val1,count(distint year) as totalyear from table group by val1 having count(distinct year) = @yearcnt

Something like this may work
select
value1
from
table as t1 inner join
(select distinct year from table) as t2
on t1.year=t2.year
group by
val1
having count(distinct t1.year)=(count(distinct t2.year) )
