I declare and use records, dynamic types and cursors to calculate the seller's performance.
This my code:
DECLARE
TYPE performance_type IS RECORD
(person_code person.person_code%TYPE,
person_name person.last_name%TYPE,
current_sales NUMBER (8, 2),
perform_percent NUMBER (8,1),
status varchar2(30) ) ;
one_perform performance_type;
CURSOR person_cur IS
SELECT * FROM persoon;
CREATE OR REPLACE PROCEDURE current_performance
(a_person persoon%ROWTYPE,
a_perform OUT performance_type)
BEGIN
CURSOR history_cur (pers varchar2) IS
SELECT AVG(tab2.product_price * tab1.quantity) avg_order
FROM puurchase_archive tab1, prooduct tab2
WHERE tab1.product_name = tab2.product_name
GROUP BY tab1.salesperson
HAVING tab1.salesperson = pers;
hist_rec history_cur%ROWTYPE;
current_avg_sales NUMBER(8,2) := 0;
a_perform.person_code := a_person.person_code;
a_perform.person_name := a_person.last_name;
a_perform.status := NULL;
BEGIN
SELECT SUM(tbl2.product_price * tbl1.quantity),
AVG tbl2.product_price * tbl1.quantity)
INTO a_perform.current_sales,
current_avg_sales
FROM puurchase tbl1, prooduct tbl2
WHERE tbl1.product_name = tbl2.product_name
GROUP BY tbl1.salesperson
HAVING tbl1.salesperson = a_person.person_code;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
a_perform.status := 'Current purchases exception';
a_perform.current_sales := 0;
END;
OPEN history_cur (a_person.person_code);
FETCH history_cur INTO hist_rec;
IF (history_cur%NOTFOUND) THEN
a_perform.perform_percent := 0;
IF (a_perform.status IS NULL) THEN
a_perform.status := 'Erroneous or no history';
END IF;
ELSE
a_perform.perform_percent := 100 * (current_avg_sales - hist_rec.avg_order)/
hist_rec.avg_order;
a_perform.status := 'All fine';
END IF;
CLOSE history_cur;
EXCEPTION
WHEN NO_DATA_FOUND THEN
a_perform.status := 'Exceptions found';
END current_performance;
BEGIN
FOR person_rec IN person_cur
LOOP
current_performance(person_rec, one_perform);
dbms_output.put_line(one_perform.person_code || ' ' ||
one_perform.person_name || ' ' ||

END LOOP;
END;
This code don't work with declare. ERROR: Encountered the symbol "CREATE" when expecting one of the following: begin function package pragma procedure subtype type use form current cursor.
And without DECLARE I've got warnings: [1]: Statement processed in 0,62 sec with warnings [1]: (Warning) PLS-00103: Encountered the symbol "BEGIN" when expecting one of the following: ; is with authid as cluster order using external deterministic parallel_enable pipelined The symbol "is was inserted before "BEGIN" to continue.
