Are you writing a book or something?

You seem to ask an awful lot of questions and yet never seem to provide answers.

Hi Karthi,

1) if not null with Default is specified for Date time and timestampt the DATE and Time at the time of LOAD or INSERT or Update will be updated

2) for Select * from T1,T2
if T1 has 3 rows and T2 has 2 rows the query will result in 6 rows
