Inserting tables with foreign key How can I improve this method that adds data to three tables in the database?

The tables are:


UserTable
UserInfoTable
ContactTable


UserInfoTable and ContactTable have a one-to-many relationship, with ContactTable having UserInfoID as a foreign key.

public static boolean addUser(User user) {
Connection connection = getConnection();
try {
PreparedStatement insertUser = connection.prepareStatement(Insert_User);
insertUser.setString(1, user.getUsername()); 
insertUser.setString(2, user.getPassword());
insertUser.setString(3, user.getUserType());  
insertUser.executeUpdate(); 
PreparedStatement insertUserInfo = connection.prepareStatement(Insert_UserInfo);
insertUserInfo.setString(1, user.getFirstName()); 
insertUserInfo.setString(2, user.getMiddleName());
insertUserInfo.setString(3, user.getLastName());
insertUserInfo.setString(4, user.getGender());
insertUserInfo.setString(5, user.getBirthdate());
insertUserInfo.executeUpdate();
//I need to get the UserInfoID to insert to ContactTable. I really hate to do this but I can't think of any way to insert the foreign key.
PreparedStatement getUserInfoID = connection.prepareStatement(GET_USER_INFO_ID);
getUserInfoID.setString(1, user.getFirstName()); 
getUserInfoID.setString(2, user.getMiddleName());
getUserInfoID.setString(3, user.getLastName());
getUserInfoID.setString(4, user.getGender());
getUserInfoID.setString(5, user.getBirthdate());
ResultSet rs = getUserInfoID.executeQuery();
PreparedStatement insertContact = connection.prepareStatement(Insert_Contact);
while (rs.next()) {
insertContact.setInt(1, rs.getInt(1));
insertContact.setString(2, user.getEmailAddress()); 
insertContact.setString(3, user.getAddress());
insertContact.setString(4, user.getContactNumber());
insertContact.executeUpdate(); 
}
} catch (SQLException sqle) {
sqle.printStackTrace();
return false; 
}
return true;
}


I originally want to set the connections's autocommit to false so the connection will rollback if an insert statement fails, but since I need to get the UserInfo ResultSet to get the UserInfoID, I can't do it anymore. How can I do this better?
I think you want to use transactions. Within a transaction, you can certainly do INSERT + INSERT + SELECT the UserInfoID + the final INSERT. Commit the transaction at the end, after all successful, rollback on any exception.

Rather than using the low level database APIs like managing Connection, PreparedStatement, ResultSet, yourself, I strongly recommend to use a framework for this, such as Spring's JDBC template or Apache's DbUtils. Once you step on that road life will get easier and you won't look back.
