zero errors trying to connect user to local mysql database - mysql

Question

using npm any-db and any-db-mysql
var db = anyDB.createConnection('mysql://db_user:921F9DB7pnn0ka777#localhost/db1',function(e,r){if(e){console.log('db.err: '+e);}}); // also tried 127.0.0.1
I should see the console log
db.err: null
But I don't. (I see no error at all).
db.query("SELECT * FROM btns WHERE id='1'").on('row',function(e,r){
console.log('err: '+e);
console.dir(r);
});
The above also prints nothing (not even an error);
In my ssh session mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| db1 |
| test |
+--------------------+
mysql> use db1;
mysql> show tables;
+---------------------------+
| Tables_in_db1 |
+---------------------------+
| btns |
+---------------------------+
The db_user is in database 'mysql', setup like so:
mysql> use mysql;
mysql> update user set password=PASSWORD('921F9DB7pnn0ka777') where user='db_user';
mysql> flush privileges;
mysql> exit;

Answer 1

Why would you expect the first case to ever output anything? You're only logging if the error argument is a truthy value (which null is not).
For the the second case, any-db/any-db-mysql does not emit 'row' events for the streaming (non-callback) version. The streaming version returns a readable stream, so you need to use standard methods for getting data from a readable stream (in object mode):
Listen for 'data' events where the 'data' event handler's argument is a row object.
OR call .read() repeatedly to get row objects
Also for the streaming version, you can listen for an 'error' event to check for errors.
