Oracle Error Message
PLS-00330: invalid use of type name or subtype name
Reason for the Error
A datatype or subtype specifier was mistakenly used in place of a constant, variable, or expression. For example, the code might look like IF emp_count > number THEN … — illegal; NUMBER is a datatype specifier
Solution
Replace the datatype or subtype specifier with a valid constant, variable, or expression.
