NOT NULL WITH DEFAULT indicates that the column cannot
contain a NULL, if a user doesnt enter a value, DB2
generates the default.

Answer / kumar
Using 'NOT NULL WITH DEFAULT' you can also specify you own
values. INTEGER, SMALLINT will assigned with zero, CHAR,
VARCHAR will be assigned with spaces. DATE, TIME, TIMESTAMP
will be assigned with system DATE, TIME & TIMESTAMPE values
respectively.
As the table is declared with 'NOT NULL WITH DEFAULT',
there is no chance of getting the null values during data
fetch.
