Node.js SQL Server driver issue - How to troubleshoot - node.js

Question

What is the correct way to troubleshoot this error with Node.js on Windows with the SQL Server driver.
events.js:2549: Uncaught Error: 42000: [Microsoft][SQL Server Native Client 11.0
]Syntax error, permission violation, or other nonspecific error
It is not the SQL statement - it works in other tools - like .NET
Doesn't seem to be the SQL connection info - it works in other tools - like .NET
Any thoughts? What is the correct way for completely uninstalling node.js and starting over. I don't think my last install removed all my global modules.
var sql = require('node-sqlserver');
var _ = require('underscore')._;
var connstr = "Driver={SQL Server Native Client 11.0};Server=localhost;" +
"Initial Catalog=CDDB;Trusted_Connection={Yes}";
sql.open(connstr, function (err, conn) {
if (err) {
console.log("Error opening the connection");
return;
} else {
var stmt = "select top 10 * from Client";
conn.query(connstr, stmt, function (err, results) {
if (err) {
console.log("Error running query!");
return;
}
_.each(results, function (row) {
console.log(row[0]);
});
});
}
});

First idea : Are users which runs your node.exe process and the one defined on your application pool - or maybe your current user account if you are using VS.NET to check your code are the same ?
To troubleshoot :
I would use node-inspector - it allows to set up breakpoints onto your node.js code
To install it :
npm install -g node-inspector
To run it :
node --debug your-nodeapp-file.js
Launch another command line and run the following program :
node-inspector
Sorry but i do not have SQL Server to try your code, hope this help anyway.
