Answer 1

This is all fun and games until some table references your table...

Then I must alter the code provided like so :

CREATE PROCEDURE _cascadeConstraints @database nvarchar(30) = NULL, @table nvarchar(60) = NULL
as
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
    select @sql = 'ALTER TABLE ' + tc.TABLE_NAME + ' DROP CONSTRAINT ' + tc.CONSTRAINT_NAME
      from INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc join
                  INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc on
                   (rc.CONSTRAINT_CATALOG = tc.CONSTRAINT_CATALOG and
                    rc.CONSTRAINT_NAME = tc.CONSTRAINT_NAME) join
                  INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc_pk on
                   (tc_pk.CONSTRAINT_CATALOG = rc.CONSTRAINT_CATALOG and
                    tc_pk.CONSTRAINT_NAME = rc.UNIQUE_CONSTRAINT_NAME)
     where tc.constraint_catalog = @database
       and tc_pk.TABLE_NAME = @table
    exec    sp_executesql @sql
END
