Equivalent for drop table table_name cascade constraints in SQL Server

My question is that in Oracle we can use drop table table_nam开发者_JAVA技巧e cascade constraints to drop a referenced table object. How can I achieve the same in SQL Server?

As I know there is not one command in MsSql, but you can use INFORMATION_SCHEMA and dynamic SQL.

Something like this:

DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)

set @database = 'MyDatabase'
set @table = 'MyTable'

DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
    select    @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME 
    from    INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
    where    constraint_catalog = @database and 
            table_name = @table
    exec    sp_executesql @sql
END

There is an option to let Management Studio generate a script that alters/drops all constraints on dependent objects.
