MS SQL: Alter table statements syntax

Zone: Databases Miscellaneous

Tags: alter, table, sql

hello
i am working on an MS SQL db remotely via enterprise manager. (a web site running MS SQL)

But the enterprise manager is very unreliable, alwasy breaking connections.

We would like to alter a few table structures. But havent been able to do so.

I wanted to use the alter statement via query analyzer, but not sure of the syntax.

Basically we want to Change
1. Data type
2. length
3. Null values, (ie set as Null)

Could i get help with this syntax ? (ALTER TABLE [dbo].[Users] )

Thanks
Ehi
