Ok, I'll give you another idea but it's only an idea and if your solution
works better for you, no harm done.
Since you have different database structures you still might use a view:
In db1:
create view monthyear as select distinct month, year from table_in_db1
In db2:
create view monthyear as select distinct month, year from table_in_db2

That way from both applications you fill your combo with values the same
way, select month, year from monthview;
