Expert: Peter Choi - 6/20/2009

Question
Will you please help me to implement Default constraint for multiple columns using alter statement.

Thank you in advance.

Answer
Hi Saravanan,

Not understanding your business requirements, I can point you to several good references on creating constraints and its management:

http://www.databasedesign-resource.com/oracle-constraints.html

http://www.dba-oracle.com/t_constraints.htm

http://www.adp-gmbh.ch/ora/misc/integrity_constraints.html

Hope this helps.

Peter
