Hi All,
This REALLY is a novice question
I'm writing a simple query where i need to return [Field A]/[Field B] so i can express [Field A] as a percentage
Both of these fields are BigInts, so i always get 0
What do i need to do to the data types in my query to enable decimal places?
You can cast at least one of them to numeric:

postgres=# SELECT 7::int / 10::int;
?column?
----------
0
(1 row)

postgres=# SELECT 7::numeric / 10::int;
?column?
------------------------
0.70000000000000000000
(1 row)
