Primary & Foriegn Key Relation

Question

I have to tables TABLE-A, TABLE-B
CREATE TABLE A(HEADER_ID NUMBER(4) PRIMARY KEY,BROKER_CODE VARCHAR2(10),E_DATE DATE,AGENT VARCHAR2(10))
CREATE TABLE B(LINE_ID NUMBER(4) PRIMARY KEY,HEADER_ID NUMBER REFERENCES XX_JVG_HEADER(HEADER_ID),INVOICE_NO NUMBER(4),LOT_NO NUMBER(4))
1) I will insert the data manually raaa.I'm taking HEADER_ID as a Primary Key in Table-A & Foriegn Key in Table-B.
2) Again i have taken LINE_ID as a Primary Key in Table-B .If i try to insert the data into Table-B the HEADER_ID automatically should enter in Table-B.
3) But the HEADER_ID should be the same for Table-A & Table-B.
Table-A
2,'abc','12-mar-2002','chennai'
Table-B
1,2,1,1
Header_id should be same in 2 tables i.e -- 2
we have to create triggers or any...pls let me know ASAP.

Answer 1

So what is the issue with the tables? The script above looks ok to me, assuming table A is really called XX_JVG_HEADER, although you should really define B.HEADER_ID as NUMBER(4).
If i try to insert the data into Table-B the HEADER_ID automatically should enter
in Table-BThis is not something you can do in the table creation script or with triggers. You're inserting data manually so only the front-end program (or you if you're using something like sql plus) can know which record in table A is the parent of the new records in table B, so that will decide the value to insert into the header_id column. I suspect that this line, as well as the fact that this is Forms forum, prompted answers concerning master-detail forms. For database issues you should use the sql forum.
