To declare a cursor variable, you use the REF CURSOR is the data type. PL/SQL has two forms of REF CURSOR typeS: strong typed and weak typed REF CURSOR. The following shows an example of a strong REF CURSOR. REF CURSOR types may be passed as parameters to or from stored procedures and functions. The return type of a function may also be a REF CURSOR type.

If you want to access the values in SQL*Plus / SQL Dev, pass a refcursor variable: PROC b (no commits or OUT parameters) PROC c (REF CURSOR OUT parameter and commits) "A" calls "b" using a DBLINK works fine. "A" calls "b" and "b" calls "c" does not work(ORA-02064) Other than removing the COMMIT statements in proc C do you see any other workaround for this problem.

Example: Returning a REF CURSOR from a procedure (PL/SQL) This example demonstrates how to define and open a REF CURSOR variable, and then pass it as a procedure parameter. The cursor variable is specified as an IN OUT parameter so that the result set is made available to the caller of the procedure:

It is useful when writing general-purpose and flexible programs like ad hoc query systems, when writing programs that must execute DDL statements, or when you do not know at compilation time the full text of a SQL statement or the number or data types of its input and output OPEN-FOR-USING Statement. The OPEN-FOR-USING statement associates a cursor variable with a query, executes the query, identifies the result set, positions the cursor before the first row in the result set, then zeroes the rows-processed count kept by %ROWCOUNT. Example: Returning a REF CURSOR from a procedure (PL/SQL) This example demonstrates how to define and open a REF CURSOR variable, and then pass it as a procedure parameter. The cursor variable is specified as an IN OUT parameter so that the result set is made available to the caller of the procedure: Corresponding formal and actual cursor variable parameters must have compatible return types. Otherwise, PL/SQL raises the predefined exception ROWTYPE_MISMATCH. To pass a cursor variable parameter between subprograms in different PL/SQL units, define the REF CURSOR type of the parameter in a package.

This provides the capability to modularize the operations on a cursor into separate programs by passing a cursor variable between programs. Cursor Variables.
