Problem Solved
For example -
Table A | Username(PK)| Address|
Table B | ID | Phone | Username(FK)|
Table C | SN | Brand | Model | Username(FK)
rs = st.executeQuery
("SELECT * FROM (A Inner Join B on A.Username = B.Username) Inner Join C on A.Username = C.Username");
if anyone looking for inner join 3 tables together by Using JAVA and Link to Access use the referenece above.
Make sure you must link the table relationship in Access before run the java program if not it will pop out "ERROR IN ROW"
Thanks everyone who helping me :)
