Oracle PL/SQL cursor update - sql

Question

I'm using oracle. My SQL skills are very bad, I want to update information from a query that I have obtained through the use of a cursor, I've read about using the WHERE CURRENT OF statement, but I don't see how that can fit into my current code. Does anyone mind lending a helping hand? I want to allow a calling program to update a row in the cursor (I want to update the race location) returned by the query in my current code. Here's my code so far:
DECLARE
l_race_rec race%rowtype;
CURSOR Query1
IS
SELECT *
FROM RACE
WHERE Race_Time='22-SEP-14 12.00.00.000000000';
BEGIN
OPEN Query1;
LOOP
FETCH query1 INTO l_race_rec;
EXIT WHEN query1%notfound;
dbms_output.put_line( l_race_rec.raceid || ', ' || l_race_rec.race_location || ', ' ||
l_race_rec.race_type || ', ' || l_race_rec.race_time || ', ' || l_race_rec.sex || ', ' ||
l_race_rec.minage || ', ' || l_race_rec.maxage );
END LOOP;
CLOSE Query1;
END;

Answer 1

Here's an example to get you going:
DECLARE
l_race_rec race%rowtype;
CURSOR Query1 IS
SELECT *
FROM RACE
WHERE Race_Time = '22-SEP-14 12.00.00.000000000';
nSome_value NUMBER := 42;
BEGIN
OPEN Query1;
LOOP
FETCH query1 INTO l_race_rec;
EXIT WHEN query1%notfound;
dbms_output.put_line(l_race_rec.raceid || ', ' ||
l_race_rec.race_location || ', ' ||
l_race_rec.race_type || ', ' ||
l_race_rec.race_time || ', ' ||
l_race_rec.sex || ', ' ||
l_race_rec.minage || ', ' ||
l_race_rec.maxage );
UPDATE RACE
SET SOME_FIELD = nSome_value
WHERE CURRENT OF QUERY1;
END LOOP;
CLOSE Query1;
END;
Share and enjoy.

Answer 2

Why don't you use a cursor for loop.
...
for row in query1
loop
dbms_output.put_line(row.raceid || ', ' ||
row.race_location || ', ' ||
row.race_type || ', ' ||
row.race_time || ', ' ||
row.sex || ', ' ||
row.minage || ', ' ||
row.maxage );
UPDATE RACE
SET SOME_FIELD = nSome_value
WHERE CURRENT OF QUERY1;
end loop;
...
In this way there no need to open and to close a cursor.
Keep in mind that a cursor for loop works better for a cursor with more than 1 row as result.
Good luck.
