Answer / guest

Cause: In a declaration, the name of a variable or cursor is
misspelled or the declaration makes a forward reference.
Forward references are not allowed in PL/SQL. A variable or
cursor must be declared before it is referenced it in other
statements, including other declarative statements. For
example, the following declaration of dept_rec raises this
exception because it refers to a cursor not yet declared:
DECLARE dept_rec dept_cur%ROWTYPE; CURSOR dept_cur IS SELECT
... ...

Action: Check the spelling of all identifiers in the
declaration. If necessary, move the declaration so that it
makes no forward references.
