Question

我有一个调查问卷的存储过程，可以更新问题，可能的答案和给出的答案。我遇到的问题是问题是真/假或是/否问题，还是有4个可能答案的多项选择题。

对于每个可能的答案我是否需要一个新的变量名称，如@ PossibleANswert1，@ PossibleAnswer2或者我可以只有一个吗？

到目前为止，我有这个：

    BEGIN
    IF @Question_Type = 1 //a 1 means its a two answer question otherwise it will be a 4 answer question
    BEGIN

    Insert into QUESTIONS
    (QuestionType, Question_Text, Questionaire_ID, Filter)--
    Values
    (@Question_Type, @New_Question, @Questionnaire_ID, @Filter)

    select  @NewQuestion_ID = SCOPE_IDENTITY()-- 

    insert into Possible_Answers
    (Question_ID, Explanation_Required, Review_Required, Possible_Answer_Text, Question_Type)
    values 
    (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type), // true/false or yes/no
    (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type)

    insert into GIVEN_ANSWERS
    (Question_ID, Answer_Text, Explanation_Text, Sample_ID)
    values
   (@NewQuestion_ID, @Given_Answer, @Explanation_Text, @Sample_ID) 

   END
   ELSE 
   BEGIN
   Insert into Questions
   (QuestionType, Question_Text, Questionaire_ID, Filter)--
   Values
   (@Question_Type, @New_Question, @Questionnaire_ID, @Filter)

   select  @NewQuestion_ID = SCOPE_IDENTITY()

   insert into Possible_Answers
   (Question_ID, Explanation_Required, Review_Required, Possible_Answer_Text, Question_Type)
   values 
   (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type), // mulitple choice
   (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type),
   (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type),
   (@NewQuestion_ID, @Explanation,@Review,@Possible_Answer,@Question_Type)

   insert into GIVEN_ANSWERS
   (Question_ID, Answer_Text, Explanation_Text, Sample_ID)
   values
   (@NewQuestion_ID, @Given_Answer, @Explanation_Text, @Sample_ID)
   END

   END

我对存储过程比较陌生，所以请随意调出任何其他错误或编码不好

Answer 1

我相信你要找的是用户定义的表类型。这将允许您使用任意数量的列传递任意数量的可能答案。

create type dbo.possible_answer as table(
  answer nvarchar(max),
  explaination nvarchar(max),
  review nvarchar(max)
);

create procedure dbo.create_question
 @QuestionType int,
 ....(Other params here)
 @PossibleAnswers dbo.possible_answer readonly
as
begin
....(some code)
   insert into Possible_Answers
    (Question_ID, Explanation_Required, Review_Required, Possible_Answer_Text, Question_Type)
    select @NewQuestion_ID,
    p.explaination,
    p.review,
    p.answer,
    @Question_Type
     from dbo.possible_answer p;
...(other code)
end

存储过程中的变量不同或相同
