AAAA BED 12345
AAAA EDU CESS 1234
AAAA SHECESS 123
AAAA CST 3% 12456
AND SO ON.
Now i want to convert the rows in Column heading TEDCODE to columns. But i want the specific rows like BED, EDU CESS, SHECESS in one column suppose EXCISE, and the other row i.e CST 3% in other column under heading TAX.

Answer 1

SQL> create table t (itemcode varchar(4),tedcode varchar(10),amount number);
Table created.
SQL> insert into t values('AAAA','BED',12345);
1 row created.
SQL> insert into t values('AAAA','EDU CESS',1234);
1 row created.
SQL> insert into t values('AAAA','SHECESS',123);
1 row created.
SQL> insert into t values('AAAA','CST 3%',12456);
1 row created.
SQL> select itemcode, tedcode,decode(tedcode,'CST 3%',null,amount) EXCISE, decod
e(tedcode,'CST 3%',amount,null) TAX from t;
ITEM TEDCODE    EXCISE                                          TAX
AAAA BED        12345
AAAA EDU CESS   1234
AAAA SHECESS    123
AAAA CST 3%                                                   12456
