Dear Hermit,
I didn't ask the question just for the sake of asking...
The design in my module is such that for any requests from the client side,
I have to do some DB operation. The operation could be either SELECT,
UPDATE, INSERT or DELETE in the database depending on the request id and the
data in the database. So, I am having a meta-data table in the database,
which will tell me what kind of operation to do on a particular request id,
what are the tables involved, what are the columns involved, what are the
keys for these tables, and what are the relations(join conditions) between
the tables involved. So, here in column names, I am storing columns in the
tablename.columnname format, becuase columns can be from many tables.
Here comes the problem specified in my query earliar...
If you have an idea, ORACLE supports tablename.columnname format in all
INSERT, SELECT, UPDATE and DELETE queries.
Anyway, thanks for your reply...
Thanks and regards,
Vijay

stupid question, but why would you use that format instead of doing:
INSERT INTO a ( a, b ) VALUES ( 'xyz', 'abc' );
Why the tablename. in front?
