我想你的數據結構是這樣的:
Table1 :Test
id:
TestName:
Table2: Questions:
id:
test_id:
Question:
Answer: //say a,b,c,d
Table3:Answers
id:
question_id:
Anwser Option: //say a,b,c,d
Answer:
SQL進行數據表: 這些數據將幫助您瞭解的結構。
CREATE TABLE IF NOT EXISTS `Tests` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`Test` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;
--
-- Dumping data for table `test2`
--
INSERT INTO `test2` (`id`, `Test`) VALUES
(1, 'Test1');

從表中選擇基於一個唯一的ID將採取「時間的大量」?我們以皮秒爲單位進行測量嗎? –
