For data type char:
String query = "ALTER TABLE [dbo].["+tablename+"] ADD [columnname] [char] (60) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL";
For data type int:
String query = "ALTER TABLE [dbo].["+tablename+"] ADD [columnname] [int] NOT NULL";________________________
is what's wrong with the code?

Best solution would be to look up the exact syntax from the SQL Server 2000 documentation. The tutorial you have there teaches the ANSI Standard SQL. It is surprising that SQL Server 2000 (Microsoft right?) doesn't comply with that (especially since they list it in as one of the ones the tutroial was made to demonstrate).
I would double and triple check your sintax, whatch your error logs to make sure something else isn't preventing you from changing, and making sure you are logged in to the DB as a user who has the ability to alter tables.
