connection.query('

SET @update_id := 0; 

UPDATE relations set x1 = ?, y1 = ?, id = (SELECT @update_id := id) WHERE element_to =?;

SELECT @update_id;',[data.x2,data.y2,id],function(err,result){

if(err){console.error(err);}

else{console.log(result);console.log(result.@update_id);}

});

I am getting the following result from a query execution:

[ RowDataPacket {

  '@update_id': 'WAbWA1WA5WA2WA8WAdWA4WA9' } ] ]

How do I access the @update_id field to store the value in a variable. I know these are objects and I tried the following to access them such as follows:

results.@update_id; 

But I get undefined when I try to log the value. How to get the value?
