The console log statement not working when select query is executed

[thaihoc]

I have installed the node-oracle module and have connected to an oracle database successfully. But, I have a problem when I execute a select query. My code is below (the file name is tests-connection.js):

    
    connection.execute("SELECT * FROM DM_LINH_VUC", [], function(err, results){
        if (err) { console.log("Error executing query:", err); return; }
                
                        
        console.log(results); //This statement's not working
        connection.close(); 
    });
    

The output in Node.js command prompt (nothing):

    C:\xampp\htdocs\motcua.dev\public\socket.io\node_modules\oracle>node tests-connection
    C:\xampp\htdocs\motcua.dev\public\socket.io\node_modules\oracle>

I have tried to update a record and it works, but when I execute a select query I do not see any output in the console log statement. The terminal is empty until the code that is executing is finished.

How can one fix this problem?

Thanks
