Oracle Error Message
PLS-00215: String length constraints must be in range (1 .. 32767)
Reason for the Error
When a character variable was declared, a length outside the legal range was specified. For example, the following declarations are illegal: flag CHAR(0); — illegal; zero length name VARCHAR2(-10); — illegal; negative length
Solution
Change the length constraint, making sure that it lies in the range 1 .. 32767.
