Angka (-1) hanya u/ mengubah nilai data menjadi negatif
Sementara penjumlahan dilakukan oleh fungsi SUM
Bisa dilihat contoh dibawah:
SQL> CREATE TABLE account (
2 account_no varchar2(1),
3 amount number(5));
Table created.
SQL> INSERT INTO account VALUES ('D',500);
1 row created.
SQL> INSERT INTO account VALUES ('C',400);
1 row created.
SQL> INSERT INTO account VALUES ('D',200);
1 row created.
SQL> INSERT INTO account VALUES ('C',100);
1 row created.
SQL> SELECT * FROM ACCOUNT;
ACCOUNT_NO AMOUNT
-------------------- ----------
D 500
C 400
D 200
C 100
SQL> SELECT SUM( DECODE(account_no,'D', amount, amount * (-1))) SUM FROM
ACCOUNT
2 GROUP BY ACCOUNT_NO;
ACCOUNT_NO SUM
-------------------- ----------
D 700
C -500
