cursor_variable_name:

This identifies a cursor variable or the parameter formerly declared within the present scope.

host_cursor_variable_name:

This identifies the cursor variable formerly declared in a PL/SQL host atmosphere and passed to the PL/SQL as a bind variable. The host cursor variable datatype is well-suited with the return type of any PL/SQL cursor variable. The Host variables should be prefixed with a colon.

select_statement:

This is a query related with the cursor variable that returns a set of values. The query can reference the bind variables and PL/SQL parameters, variables, and functions but cannot be FOR UPDATE. The syntax of the select_statement is similar to the syntax for the select_into_statement.
