simplify multiple sql queries different variable - sql

Question

I am trying to better automate my queries so I don't have to change the table name and where clause each time. Right now this is what I do:
Years 2014, 2013, etc. I might out these variables into a table. Also doing this on Oracle.
Colors: Red, Green, etc
select count(*) from Apples_2014
where Type = 'Red'
;
select count(*) from Apples_2014
where Type = 'Green'
;
select count(*) from Apples_2013
where Type = 'Red'
;
select count(*) from Apples_2013
where Type = 'Green'
;
Is there a simpler way to do this so I have only one query and then it gets run multiple times but with the different parameters?
Also through some research I saw I can use && which then creates a popup each time in Toad. This isn't really efficient though but its kinda works.

ADDITION (original answer below. Editing after seeing your comment on your post.)
Sounds like you actually want do to grouping.
Running something like the below will give counts for all tables and all values at once in a single result set.
select count(*) as total, 'TABLENAME' as tablename, value
from Tablename
group by value;
UNION ALL
select count(*) as total, 'TABLENAME2' as tablename, value
from Tablename2
group by value

Original answer:
you can use bind variables in Oracle - it will then prompt for each value.
select count(*) from TABLE
where Type = :value
assuming your table structures are very similar, you can union and add a paramater to handle the table name changes without switching to use dynamic sql (dynamic sql is just writing it as a concatenated string - not very efficient.).
So like this....
select total
from (
select count(*) as total, 'TABLENAME' as tablename
from Tablename
where type = :value;
UNION ALL
select count(*) as total, 'TABLENAME2' as tablename
from Tablename2
where type = :value
) a
where a.tablename = :tablename
