Your question is not complete so answering based on the information what we have -

You need to use
INSERT INTO ...SELECT statement for insertion in the table 3.

Something like 

INSERT INTO userrole (column1, column2, column3)
SELECT user.column1, user.column2, role.column3
FROM user, role
WHERE user.column1 = role.column1;
