You can export any Oracle view as a Postgres Pro table simply by
setting TYPE configuration option to TABLE to have the
corresponding create table statement. Or use type COPY or INSERT to
export the corresponding data. To allow that you have to specify
your views in the VIEW_AS_TABLE configuration option.
Then, if ora2pgpro finds the view,
it extracts its schema (if TYPE=TABLE)
into a Postgres Pro CREATE TABLE
form, then it will extract the data (if TYPE=COPY
or TYPE=INSERT) following the view schema.
For example, with the following view:
CREATE OR REPLACE VIEW product_prices (category_id, product_count, low_price, high_price) AS
SELECT category_id, COUNT(*) as product_count,
MIN(list_price) as low_price,
MAX(list_price) as high_price
FROM product_information
GROUP BY category_id;
Setting VIEW_AS_TABLE to product_prices and using export type TABLE, will force ora2pgpro to detect columns returned types and to generate a create table statement:
CREATE TABLE product_prices (
category_id bigint,
product_count integer,
low_price numeric,
high_price numeric
);
Data will be loaded following the COPY
or INSERT export type and
the view declaration.
You can use the ALLOW and
EXCLUDE directives in addition
to filter other objects to export.
