Answer / krishna tammana
Cognos SQL and Native SQL are two different types of SQL
generated by cognos tool. Native SQL is sub set or same as
Cognos SQL.
Native SQL contains only the functionality that got
executed at database end, apart from this Cognos SQL will
have the Locally processed logic as well.

(1)The FWM uses cognos SQL as a default SQL to create and
edit query subjects.
(2)cognos sql supports SQL 99 standards, which are used in
modifying the query subjects.
Where as
(1) The native SQL is the SQL the database uses such as
oracle,sql secver etc.
(2) A cognos query definition engine (QDE) convert the
cognos SQL into a native SOL which will be submitted to the
data source to query the data.

Answer / sridhar
It depends upon the requirement of Report as well database .
If report wants to show from the different database cognos
sql is most prefarable because it can fetch
from multiple databases.
also for calculation as well other complicated business
rules Cognos sql its preferred.
also we can hide the underline tables as well database
source.
Advantage of native SQL will be no need of metadata .
We are passing the Query to native to handle it.
In my experince column name was case senstive if it changes
it was throwing error - isnt wiered :-(.
