SQL Server 2008 Management Studio修改表后不能保存如何解决？下面看实例。

安装了SQL Server 2008  Express+SQL Server 2008 Management Studio.在修改一个数据库表格的结构后保存时，出现如下错误提示：
“Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created”

提示信息：
"or enabled the option Prevent saving changes that require the table to be re-created."
 
要修改表格，只需要修改Tools-> Options -> Designers 然后将“Prevent saving changes that require table re-creation ”前的勾选去掉便OK了。
