Oracle inserts data into multiple tables at the same time

During Oracle operations, data is often inserted into multiple different tables at the same time. This statement is very suitable. "All" indicates a non-short-circuit operation, that is, if the First condition is met, you must run the following command to check whether other conditions are met. However, if the First condition is found for the short-circuit operation, the operation will not proceed downward. INSERT ALL

WHEN prod_category = 'B' THEN

INTO book_sales (prod_id, cust_id, qty_sold, amt_sold)

VALUES (prodUCt_id, customer_id, sale_qty, sale_price)

WHEN prod_category = 'V' THEN

INTO video_sales (prod_id, cust_id, qty_sold, amt_sold)

VALUES (product_id, customer_id, sale_qty, sale_price)

WHEN prod_category = 'A' THEN

INTO audio_sales (prod_id, cust_id, qty_sold, amt_sold)

VALUES (product_id, customer_id, sale_qty, sale_price)

SELECT prod_category, product_id, customer_id, sale_qty

When matched then update set pi. list_price = np. list_price

When not matched then insert (pi. product_id, pi. category_id

, Pi. list_price, pi. min_price)

VALUES (np. product_id, 33, np. list_price, np. min_price );
