Thanks for responding!
Wouldn’t you have to create the function to stop the original function until it’s finished? Similar to for-loop or multiple functions of fs?

Could you explain to me again what these functions are for? If I go through this with sample numbers, it doesn’t make sense. But I’m the one who asks for help in the forum...

  // Access query results

    // Do something with the results of the first query

Thank you for your efforts and your time and I hope to get another answer from you.

Hey guys,

I need your help with a problem I’ve been able to walk around so far.
Namely, I want to make a mysql query in a node.js web socket:

 connection.query("SELECT * FROM DB WHERE id= ?;", [id], function(error, results, fields) {
            if (error) throw error;
         	// Code here...
        })

In the variable results I can now use the data in the form of a JSON object. That’s not a problem.
So far, I have done this so that when I wanted to make several queries, I have nested into each other. Like this:

 connection.query("SELECT * FROM DB WHERE id= ?;", [id], function(error, results, fields) {
            if (error) throw error;
         	 connection.query("SELECT * FROM DB WHERE id= ?;", [id], function(error, results, fields) {
            if (error) throw error;
         	// Code here...
        })
        })

But now I need that some queries are only carried out if certain conditions are met. As a result, the queries can no longer be logically nested.
That’s why I need something like this:

if(a == b) {
	 connection.query("SELECT * FROM DB WHERE id= ?;", [id], function(error, results1, fields) {
            if (error) throw error;
         	// Code here...
        })
}

if(c == b) {
	 connection.query("SELECT * FROM DB WHERE id= ?;", [id], function(error, results2, fields) {
            if (error) throw error;
         	// Code here...
        })
}

And after both if loops I can logically no longer access the values results1 and results2.
How can I do that? Do you need more information.

I hope for some answers.

Yours, Ben
