Re: Display Parent Accounts with Child Accounts

Question

I am creating an Accounts Application and whenever the User query for particular Account Transactions, that Account's Parent Accounts must also return.
Here is the DML.
CREATE TABLE MYACC
(ACC_NO NUMBER(3), PARENTID NUMBER(3),
ACC_NAME VARCHAR2(20));
INSERT INTO MYACC VALUES(111,NULL,'ASSETS');
INSERT INTO MYACC VALUES(112,111,'CURRENT ASSETS');
INSERT INTO MYACC VALUES(113,112,'RECEIVABLES');
INSERT INTO MYACC VALUES(114,111,'FIXED ASSETS');
INSERT INTO MYACC VALUES(115,113,'MACHINERY');
CREATE TABLE MYTRANS
(TRANS_DATE DATE, ACC_NO NUMBER(3),
BRANCH NUMBER(1),TRANS_AMT NUMBER(10));
INSERT INTO MYTRANS VALUES('01-JUL-2006',113,1,10000);
INSERT INTO MYTRANS VALUES('01-AUG-2006',113,1,11000);
INSERT INTO MYTRANS VALUES('01-SEP-2006',113,2,12000);
INSERT INTO MYTRANS VALUES('01-OCT-2006',113,3,13000);
INSERT INTO MYTRANS VALUES('01-NOV-2006',115,3,12100);
INSERT INTO MYTRANS VALUES('01-DEC-2006',115,3,13200);
INSERT INTO MYTRANS VALUES('01-JAN-2007',115,3,15400);
INSERT INTO MYTRANS VALUES('01-FEB-2007',115,3,13000);
If I query for Branch No. 3,
and Trans_Date between 1st July 2006 to 31st Dec 2006
following should be displayed.
Branch     Account          Trans_Date     Trans_Amt
3     Assets     
3     Current Assets     
3     Receivables     01-OCT-2006     13100     
3     Fixed Assets
3     Machinery     01-NOV-2006     12100     
3     Machinery     01-DEC-2006     13200
If I query for Branch No. 3 and Account No. 115
following should be displayed.
Branch     Account          Trans_Date Trans_Amt
3     Assets     
3     Fixed Assets
3     Machinery     01-NOV-2006     12100     
3     Machinery     01-DEC-2006     13200
Any idea please ?
