Oracle Error Message

PLS-00224: object ‘string’ must be of type function or array to be used this way

Reason for the Error

An identifier being referenced as a function or an array actually represents an object (a number or date, for example) that cannot be referenced in this way.

Solution

Check the spelling and declaration of the identifier. Also confirm that the declaration is placed correctly in the block structure.
