Hi,

Can anyone help me understanding where to store the static SQL code (Database or Application).

Consider a scenario, that I am executing a simple SQL from Java which is returning some value, and it will not be changed in future.

Can anyone suggest me, should I store this sql in java application code or in database in form of procedure/function and returning the result to Java. Is there any security/performance impact?

Thanks,
Manu

The maximum way to secure and restrict the access is to store it in a PL/SQL package and returns a ref cursor but the application must not forgot to close it when it no more needs it.

Got it.

One more question on top of that, once I was facing an interview.
Interviewer asked that we can return REF cursor and Collection both, give me a scenario when REF Cursor should be returned and when Collection should be returned.

I was clueless, and still don't know the answer.

Manu

The answer is simple, always use REF CURSOR, never use collection.
