For example, you want to write a report showing each customer along with a flag showing whether the customer has had any orders in the past five years. Y 5 Gentech Industries Y 6 Spartan Industries N 7 Wallace Labs N 8 Zantech Inc. N 11 Glaven Technologies N 12 Johnson Labs N 13 Kimball Corp. In this example, two transition types are defined: positive (POS) and negative (NEG).Using conditional logic, you can include a correlated subquery on the TRUNC(SYSDATE) - (5 * 365)), 'N', 'Y') has_recent_orders FROM customer c; CUST_NBR NAME H ---------- ------------------------------ - 1 Cooper Industries Y 2 Emblazon Corp. For example, an order in the Delayed state can make a positive transition to Processing or a negative transition to Cancelled.You create a user-defined function called SELECT supplier_name, part_name, p.part_nbr part_number p.inventory_qty in_stock, p.resupply_date resupply_date, my_pkg.get_resupply_date(p.part_nbr) acme_resupply_date FROM part p INNER JOIN supplier s ON p.supplier_id = s.supplier_id; column if the supplier's name is Acme Industries. Unfortunately, the server is forced to make 10,000 trips across the gateway when only 100 are required.You kick off the report, sit back, and wait for the results. In these types of situations, it is far more efficient to call the function only when necessary, instead of always calling the function and discarding the results when not needed: SELECT supplier_name, part_name, p.part_nbr part_number, p.inventory_qty in_stock, DECODE(s.name, 'Acme Industries', my_pkg.get_resupply_date(p.part_nbr), p.resupply_date) resupply_date FROM part p INNER JOIN supplier s ON p.supplier_id = s.supplier_id; SELECT supplier_name, part_name, p.part_nbr part_number, p.inventory_qty in_stock, CASE WHEN = 'Acme Industries' THEN my_pkg.get_resupply_date(p.part_nbr) ELSE p.resupply_date END resupply_date FROM part p INNER JOIN supplier s ON p.supplier_id = s.supplier_id; Now the user-defined function is only executed if the supplier is Acme, reducing the query's execution time drastically.For example, you have a table that records information such as the total number of orders and the largest order booked during the current month.Here's the table definition:describe mtd_orders; Name Null?For more information on calling user-defined functions from SQL, see Chapter 11.If your database design includes denormalizations, you may run nightly routines to populate the denormalized columns.

There are 10,000 parts in your database, but only 100 require information via the gateway.To populate these columns, you could generate two more update statements, each targeted to a particular region, as in: /* Europe buckets */ UPDATE mtd_orders mtdo SET (mtdo.europe_tot_orders, mtdo.europe_tot_sale_price, mtdo.europe_max_sale_price) = (SELECT mtdo.europe_tot_orders eur_day_tot.tot_orders, mtdo.europe_tot_sale_price nvl(eur_day_tot.tot_sale_price, 0), CASE WHEN eur_day_tot.max_sale_price mtdo.europe_max_sale_price THEN eur_day_tot.max_sale_price ELSE mtdo.europe_max_sale_price END FROM (SELECT COUNT(*) tot_orders, SUM(co.sale_price) tot_sale_price, MAX(co.sale_price) max_sale_price FROM cust_order co INNER JOIN customer c ON co.cust_nbr = c.cust_nbr WHERE co.cancelled_dt IS NULL AND co.order_dt = TRUNC(SYSDATE) AND c.region_id IN (SELECT region_id FROM region START WITH name = 'Europe' CONNECT BY PRIOR region_id = super_region_id)) eur_day_tot); /* North America buckets */ UPDATE mtd_orders mtdo SET (mtdo.northamerica_tot_orders, mtdo.northamerica_tot_sale_price, mtdo.northamerica_max_sale_price) = (SELECT mtdo.northamerica_tot_orders na_day_tot.tot_orders, mtdo.northamerica_tot_sale_price nvl(na_day_tot.tot_sale_price, 0), CASE WHEN na_day_tot.max_sale_price mtdo.northamerica_max_sale_price THEN na_day_tot.max_sale_price ELSE mtdo.northamerica_max_sale_price END FROM (SELECT COUNT(*) tot_orders, SUM(co.sale_price) tot_sale_price, MAX(co.sale_price) max_sale_price FROM cust_order co INNER JOIN customer c ON co.cust_nbr = c.cust_nbr WHERE co.cancelled_dt IS NULL AND co.order_dt table and aggregate the North American and European totals at the same time? N 25 Worcester Technologies N 26 Alpha Technologies Y 27 Phillips Labs N 28 Jaztech Corp. N 30 Wallace Industries N As a general rule, you should write your code so that unexpected data values are handled gracefully.
