Node.js SQL 准备查询的服务器单引号问题

Question

I'm trying to pull data from a SQL Server database using node.js, and passing the data to Google Chatbot.

This is what my SQL Server query looks like

INSERT INTO @Return
    SELECT 'You' + '\' + 've assigned ' + CONVERT(varchar(4), COUNT(1)) + ' to yourself'

This is the function that sends the data to the Google Chatbot.

function GbWebhookFunction(){

    this.sendMessage = async function(strMessage){
        console.log(strMessage);
        fetch(webhookURL, {
            method: 'POST',
            headers: {
            'Content-Type': 'application/json; charset=UTF-8',
            },
            body: "{'text': '" + strMessage + "'}",
        }).then((response) => {
            console.log(response);
        });
    };
};

This outputs:

You\ve assigned X to yourself

I tried to add to my function the code below but that did not work.

strMessage = strMessage.replace("\", "'");

I removed one \ from my SQL query but that outputted:

Youe assigned X to yourself

Output when I remove \ from the SQL query

Any ideas on how I can replace the \ with a single quote?

Answer 1

In your query you forgot to add the single quote. The query should most likely be

INSERT INTO @Return
    SELECT 'You\'ve assigned ' + CONVERT(varchar(4), COUNT(1)) + ' to yourself'

Edit

Based on some provided errors I would instead suggest using the double single quotes. Which means the SQL query should be as followed:

INSERT INTO @Return
    SELECT 'You''ve assigned ' + CONVERT(varchar(4), COUNT(1)) + ' to yourself'
