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

PLS-00224: object 'string' must be of type function or array to be used this way
Cause: 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.
Action: Check the spelling and declaration of the identifier. Also confirm that the declaration is placed correctly in the block structure.
