sp_rename
更改当前数据库中用户创建对象（如表、列或用户定义数据类型）的名称。
示例
A. 重命名表
下例将表 customers 重命名为 custs。
EXEC sp_rename 'customers', 'custs'
B. 重命名列
下例将表 customers 中的列 contact title 重命名为 title。
EXEC sp_rename 'customers.[contact title]', 'title', 'COLUMN'

而修改数据库名则用
sp_renamedb [ @dbname = ] 'old_name' , [ @newname = ] 'new_name'
