Answer 1

The Table Structure:-
PROB_ID VARCHAR2(50)
PERSON_NAME NOT NULL VARCHAR2(50)
MODULE NOT NULL VARCHAR2(100)
START_DATE DATE
VERSION NOT NULL VARCHAR2(50)
ASSIGNED_BY VARCHAR2(100)
FUNCTIONALITY VARCHAR2(4000)
ERR_TYPE VARCHAR2(150)
ERR_COMPONENT VARCHAR2(100)
ERR_LOCATION VARCHAR2(250)
PROB_DESC VARCHAR2(4000)
PROB_SOLTN VARCHAR2(4000)
STATUS VARCHAR2(100)
END_DATE DATE
and the code is in When-button-pressed
