I am trying to dynamically create a SQL select statement to retrieve only one piece of data (a sum). Is there an easy way for me to do this? My reason for doing this dynamically (or at least attempting to do so) is because I have 6 fields-- Q1, Q2, Q3, etc... and I'd like to be able to call a function and just pass in the number so I can do the SQL statement against the column based on the value coming in. ie.
SELECT SUM(X)
FROM TABLE
WHERE 'COL' = INPUT VARIABLE

with col being determined in the beginning of the function.

Any ideas??

In Oracle 8i, the EXECUTE IMMEDIATE statement prepares (parses)
and immediately executes a dynamic SQL statement
or an anonymous PL/SQL block.

The syntax is

EXECUTE IMMEDIATE dynamic_string
[[INTO {define_variable[[, define_variable]]... | record}]]
[[USING [[IN | OUT | IN OUT]] bind_argument
[[, [[IN | OUT | IN OUT]] bind_argument]]...]];
