I'm working on converting a stored procedure from SQL server to Oracle. This stored procedure provides a direct resultset. I mean that if you call the stored procedure in eg Management Studio you directly obtain the resultset.
By converting to Oracle I walk against the problem that I in Oracle will not display the resultset
I searched on the Internet and have seen that the stored procedure should yield a REF CURSOR, but I still walk with the problem to write a little piece of code to obtain the resultset en process that.
Pseudo Code:
Call stored procedure and obtain cursor Do something with that cursor so that my resultset appears
Someone an idea?

To return a cursor from an Oracle stored procedure, the output parameter of the procedure must be declared as a cursor type. You must also declare that parameter as a cursor in the LWJDBC adapter. Below is a complete working example utilizing existing pools and a Sterling Integrator table.
A stored procedure does not have a return value but can optionally take input, output, or input-output parameters. A stored procedure can return output through any output or input-output parameter.
To make the migration of other databases to the Oracle Database easier, Oracle Database 12c Release 1 added a new feature called implicit statement result that allows you to return one or more result sets from a stored procedure by using the dbms_sql package.
Stored procedures and functions (subprograms) can be compiled and stored in an Oracle Database XE, ready to be executed. Once compiled, it is a schema object known as a stored procedure or stored function, which can be referenced or called any number of times by multiple applications connected to Oracle Database XE.
