我会使用三个表：一个用于客户，一个用于问题一个用于答案。

I would use three tables: one for the clients, one for the questions, one for the answers.

我建​​议你将答案保存在详细信息表中，例如：

I suggest you to save the answers in a detail table, something like:

SEQU_ID		INTEGER			// Sequence independed on anything other
CUSTOMER_ID	(Up to you what you have)
FORM_ID		(Up to you what you have) // Check whether this is
                                          // allready in QUEST_ID below
QUEST_ID	(Up to you what you have)
ANSWER_IS	INTEGER			// {BOOL, DEC, VARCHAR}
ANSWER_BOOL	BOOLEAN
ANSWER_DECIMAL	DECIMAL
ANSWER_CHAR	NVARCHAR(20)		// "NVARCHAR" is Unicode compatible
