parameter_name. A variable declared as the formal parameter of a cursor.

The most important benefit of a cursor variable is that it enables passing the result of a query between PL/SQL programs. Without a cursor variable, you have to fetch all data from a cursor, store it in a variable e.g., a collection, and pass this variable as an argument. With a cursor variable, you simply pass the reference to that cursor.

Restriction on datatype. This datatype cannot have constraints (for example, NOT NULL, or precision and scale for a number, or length for a string). expression.

The most important benefit of a cursor variable is that it enables passing the result of a query between PL/SQL programs. Without a cursor variable, you have to fetch all data from a cursor, store it in a variable e.g., a collection, and pass this variable as an argument. With a cursor variable, you simply pass the reference to that cursor. With previous releases of ODP.NET, you could retrieve data from a ref cursor but you could not pass a ref cursor as an input parameter to a PL/SQL stored procedure or function.
