Combining North Pole with South Pole: JavaScript with SQL Server 2000

Every DBA/database developer would certainly be shocked to think about a relationship between client-side JavaScript and SQL Server 2000. It's real. Not every programmer knows that we can connect and break into SQL Server 2000 simply by using client-side JavaScript. This article covers the positive aspects of connecting to a SQL Server 2000 database lying on the client computer (or the browser computer).

The above code will automatically list all view names available in the SQL Server 2000 instance belonging to the client. To retrieve this information, I used a built-in class, "MSSQL_view," available in the "rootMicrosoftSQLServer" namespace. The "for" loop I used in the above code iterates for every view present in the SQL Server instance and finally retrieves only the properties of that view.
