T-SQL: Come possiamo eliminare tutti gli oggetti di un database?

Un semplice script in T-SQL per eliminare tutti gli oggetti di un Database SQL SERVER (viste, funzioni, stored Procedure):

-- variable to object name
declare @name  varchar(1000)
-- variable to hold object type
declare @xtype varchar(20)
-- variable to hold sql string
declare @sqlstring nvarchar(4000)
declare SPViews_cursor cursor for
SELECT QUOTENAME(ROUTINE_SCHEMA) + '.' + QUOTENAME(ROUTINE_NAME) AS name, ROUTINE_TYPE AS xtype
FROM INFORMATION_SCHEMA.ROUTINES
UNION
SELECT QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) AS name, 'VIEW' AS xtype
FROM INFORMATION_SCHEMA.VIEWS
open SPViews_cursor
fetch next from SPViews_cursor into @name, @xtype
while @@fetch_status = 0
begin
-- test object type if it is a stored procedure
if @xtype = 'PROCEDURE'
begin
set @sqlstring = 'drop procedure ' + @name
exec sp_executesql @sqlstring
set @sqlstring = ' '
end
-- test object type if it is a function
if @xtype = 'FUNCTION'
begin
set @sqlstring = 'drop FUNCTION ' + @name
exec sp_executesql @sqlstring
set @sqlstring = ' '
end
-- test object type if it is a view
if @xtype = 'VIEW'
begin
set @sqlstring = 'drop view ' + @name
exec sp_executesql @sqlstring
set @sqlstring = ' '
end
-- get next record
fetch next from SPViews_cursor into @name, @xtype
end
close SPViews_cursor
deallocate SPViews_cursor
