Hi !!!

This is the example given in the oracle 9i documentation.

http://download-west.oracle.com/otndoc/oracle9i/901_doc/appdev.901/a88878/adobjbas.htm#454999

CREATE TYPE satellite_t AS OBJECT (
name VARCHAR2(20),
diameter NUMBER);

CREATE TYPE nt_sat_t AS TABLE OF satellite_t;

CREATE TYPE planet_t AS OBJECT (
name VARCHAR2(20),
mass NUMBER,
satellites nt_sat_t);

CREATE TYPE nt_pl_t AS TABLE OF planet_t;

I am not able to create the table type nt_pl_t. Can anyone help me ?

Thanks
Yogita

This is what documentation says.,
Cause: An attempt was made to do one of the following: define a table type
which contained nested collection types. or define an object table
that has (perhaps nested) another table type or VARRAY type.
Action: Check the table definitions to be sure that they do not contain
nested tables or VARRAYs.

Probably, your code shud have been like this ..

CREATE TYPE planet_t AS OBJECT (
name VARCHAR2(20),
mass NUMBER,
satellites satellite_t );

But this is an example in the oracle 9i documentation. I just borrowed from that. My previous mail has the link to the example in oracle docs.

Is there any other way to represent this nested collection types?

Thanks
