Restrictions on cursor variables

There are a number of restrictions on cursor variables:

  • You cannot declare a package-level cursor variable. (You can declare such variables in packaged procedures and functions, however.)

  • You cannot assign NULLs to a cursor variable nor use comparison operators to test for equality, inequality, or nullity.

  • Neither database columns nor collections can store cursor variables.

  • You cannot use remote procedure calls (RPCs) to pass cursor variables from one server to another.
