Hi,

I have a star schema with say, 10 tables. I have to create a denormalized table( by stretching the arms and legs of the star schema and creating horribly long rows)from this star schema. I also have to load the data from the star schema into the demormalized table.

Can anyone tell me the simplest way of doing this?
Thanks!
Meena

Once you have the query you have settled on, simply do the following:
create table my_denorm_tab as (select...);

Be sure to name the any columns where you have used functions to manipulate the column. e.g. select to_char(date_col) Date_Col, ...

meena i think its easy task select all the columns from the entire schema and give where condition where you are equalizing foreign keys of fact table with primary keys of dimention tables and run the query.
