Answer / guest

Cause: A cursor declaration is improper or an identifier
referenced in the cursor declaration was not properly
declared. A return type that does not refer to an existing
database table or a previously declared cursor or cursor
variable might have been specified. For example, the
following cursor declaration is illegal because c1 is not
yet fully defined: CURSOR c1 RETURN c1%ROWTYPE IS SELECT ...
-- illegal In this case, a return type does not have to be
specified because it is implicit.

Action: Check the spelling and declaration of the cursor
name and any identifiers referenced in the cursor
declaration. Also confirm that the declaration is placed
correctly in the block structure. If a return type was
specified, make sure that it refers to an existing database
table or a previously declared cursor or cursor variable.
