Merging Table Columns?

thanks for reading.

kinda like like a UNION for columns maybe. i think that's what i'm looking for. take a look if you have a minute....

3 queries, each pretty clear (count the occurrences of a value in a column --> where someFlag='Y')...

SELECT Count(flag_A) as 'flag_A_confirmed', Year
FROM cases
WHERE flag_A = 'Y'
GROUP BY Year


SELECT Count(flag_B) as 'flag_B_confirmed', Year
FROM cases
WHERE flag_B = 'Y'
GROUP BY Year


SELECT Count(flag_C) as 'flag_C_confirmed', Year
FROM cases
WHERE flag_C = 'Y'
GROUP BY Year



but my desired output merges the columns together in one table ....

total confirmed flags for that year by type...

Yearflag_Aflag_Bflag_C
1998121533
1999161325
2000191421
2001... etc


i'm pretty sure i can do this using temp tables. any other ideas?

thanks for your input in advance. again.
