PL/SLQ - How to create query with horizontal running totals

Question

Hi:
I'm trying to create a report in the following format
Year Name Reg1 Reg2 Reg3
2001 Al 3 4 5
2001 Le 4 1 1
2001 7 5 6
2002 Sue 2 4 1
2002 Al 1 3 6
2002 Jim 6 1 3
2002 16 15 16
2003 Jim 4 -3 2
2003 Le -2 4 5
2003 20 16 23
Note that the totals are accumulating horizontally, broken on year. How do I do that, please? Thanks very much!

Whenever you post formatted text (such as query results) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
If you do that, your desired output will be much more readable:Year Name Reg1 Reg2 Reg3
2001 Al 3 4 5
2001 Le 4 1 1
2001 7 5 6
2002 Sue 2 4 1
2002 Al 1 3 6
2002 Jim 6 1 3
2002 16 15 16
2003 Jim 4 -3 2
2003 Le -2 4 5
2003 20 16 23

AlHere's one way to do that:WITH     yearly_summary     AS
     SELECT     year
     ,     SUM (SUM (reg1)) OVER (ORDER BY year)     AS reg1
     ,     SUM (SUM (reg2)) OVER (ORDER BY year)     AS reg2
     ,     SUM (SUM (reg3)) OVER (ORDER BY year)     AS reg3
     FROM     table_x
     GROUP BY year
SELECT     year, name, reg1, reg2, reg3
FROM     table_x
UNION
SELECT     year, NULL, reg1, reg2, reg3
FROM     yearly_summary
ORDER BY year, name

Corrected query.
Whenever you have a problem, please post CREATE TABLE and INSERT statements for your sample data.  For example:CREATE TABLE     table_x
( year     NUMBER
, name     VARCHAR2 (10)
, reg1     NUMBER
, reg2     NUMBER
, reg3     NUMBER
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2001, 'Al', 3, 4, 5);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2001, 'Le', 4, 1, 1);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2002, 'Sue', 2, 4, 1);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2002, 'Al', 1, 3, 6);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2002, 'Jim', 6, 1, 3);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2003, 'Jim', 4,-3, 2);
INSERT INTO table_x (year, name, reg1, reg2, reg3) VALUES (2003, 'Le', -2, 4, 5);
Also, say which version of Oracle you're using.  In this case, it may not matter.  The query above will work in Oracle 9.1 and higher.
