It is like a personal choice, if someone wants to create a weak ref cursor then they can. When using an Oracle native connection, it is possible to report off the Oracle stored procedure that created within a package and also an Oracle stored procedure that references a weakly bound REF CURSOR. The stored procedure must have a parameter that is a REF CURSOR type. Crystal Reports uses this parameter to access and define the result This is an excerpt from the book Advanced PL/SQL: The Definitive Reference by Boobal Ganesan.

There is a strongly typed ref cursor type which returns Table1%rowtype, named cur_Table1. I have a stored procedure named SP1 which has an out parameter of type cur_Table1. I'm calling this SP1 stored procedure from another database that only sees this stored procedure, but not the table or the type itself. The remaining usage like opening the cursor, selecting into the cursor and closing the cursor is the same across both the cursor types.

Create a record structure to store rows of the reference cursor in an ordinary fetch, or a record structure and associative array collection data type to store a set of rows of the reference cursor.

We are free to use this Ref-Cursor type as parameters for our sub-routines and return type for the functions without needing to create them in a package specification, as it is already done by Oracle for us.
