sql = "insert into news_base(fid,title,date,author) values("+fid+",'"+title+"','"+dateValue+"','Admin')";            statement = connection.createStatement();            statement.executeUpdate(sql);                        sql1 = "insert into news_content (cid,fid,content) values("+cid+","+fid+",'"+content+"')";            statement1 = connection.createStatement();            statement1.executeUpdate(sql1);news_content表的cid，我要用news_base的id來傳進入。。關鍵是怎么獲取到news_base表的主鍵id？
