Breaking down array of objects into separate variables for database storage (React,express,sql server)

$
0
0

I have a stored array of objects within my reactjs application which when console logged looks like this.

0: {answer: "yes↵", question: "Is the keyboard separate from the screen?", state: "Declined with soloution defined"}
1: {answer: "yes", question: "Does the keyboard tilt?", state: "Accepted"}
2: {answer: "Question declined But not a problem", question: "Is it possible to find a comfortable typing postion?", state: "Accepted"}
3: {answer: "yes", question: "Do you have a good keyboard technique?", state: "Accepted"}
4: {answer: "Question declined But not a problem", question: "Are the characters on the keyboard clear and readable?", state: "Accepted"}
5: {answer: "sgdfgdfgdf", question: "Is your mouse or other pointing device suitable to the task you're using it for?", state: "problem specified"}
6: {answer: "yes", question: "Is the mouse (or other pointing device) located sufficently close to you?  ", state: "Accepted"}
7: {answer: "sdfsdfsdfsd", question: "Is there support for your wrist and forearm when using the mouse(or other pointing device)", state: "Declined with soloution defined"}
8: {answer: "yes", question: "Does the mouse (or other pointing device) work smoothly at a speed that suits you?", state: "Accepted"}
9: {answer: "asdasdas", question: "Can you easily adjust the software settings for speed and accuracy of the pointer?", state: "Declined with soloution defined"}
10: {answer: "asdasdads", question: "Are the characters on your screen clear and readable?", state: "problem specified"}
11: {answer: "yes", question: "Is the text size on your screen confortable to read?", state: "Accepted"}
12: {answer: "asdasdasd", question: "Is the image on your screen free from flicker and jitter?", state: "Declined with soloution defined"}
13: {answer: "asdasdasd", question: "Is your screen's specification suitable for its intended use?", state: "problem specified"}
14: {answer: "yes", question: "Is the brightness and/or contrast on your screen adjustable?", state: "Accepted"}

this consists of answer, question and state (state of the answered question not state as in react components)

What I would like to do is pass these through to express so that I can upload them into my SQL database using the npm package mssql. However as these are all stored into the array I'm not sure how to split these up.

Ideally I would love to pass the whole object through to SQL and just store the whole thing in the database e.g (pseudo code)

insert into table where answer = answer and question = question and state = state

Essentially to use this with SQL how would I break these down to be used with my back end or can I pass the whole object with a specific SQL stored procedure.

create procedure StoreAnswers

@{answer_values}
as

INSERT INTO QuestionResponses                                         
(RUId, QuestionId, Date, QuestionWhenAnswered, QuestionResponse, Accepted, AssignedWorkStation )
VALUES
${answer_values}

EDIT

Stored procedure

create procedure StoreAnswers(@Results varchar(max))
as begin
  insert into QuestionResponses(QuestionResponse, QuestionWhenAnswered, State)
         select substring(value, charindex('{answer: "', value) + 10,  charindex('", ', value, charindex('{answer: "', value) + 10) -  charindex('{answer: "', value) - 10) as answer, 
                substring(value, charindex('question: "', value) + 11, charindex('", ', value, charindex('question: "', value) + 11) - charindex('question: "', value) - 11) as question,
                substring(value, charindex('state: "', value) + 8,      charindex('"}', value,  charindex('state: "', value) + 8) -     charindex('state: "', value) - 8) as state
         from string_split(@Results, char(10))    
end;

How it is passed through to the sql query from express npm

app.post("/post-question-answers", async (req, res) => {
  console.log("!called");

  let results = req.body.results;

  console.info(results);

  await sql.connect(config, function(err) {
    if (err) console.log(err);

    // create Request object
    var request = new sql.Request();
    request.input("Results", sql.VarChar, results);
    // query to the database and get the records
    request.execute("dbo.StoreAnswers", function(err, recordset) {
      if (err) console.log(err);
      // send records as a response
      res.json(recordset);
    });
  });

  res.statusCode = 400;
  res.statusMessage = "bad request";
  // res.json({ message: "Email Missing" });
});


This is the console.info(results)
