  查询一个数据库中的所有表

  以下是改变所有表架构:

  在数据库testDB中存在架构A及用户A,现将testDB数据库所属的用户由A改为B,同时删除用户A;架构也由A改为B,删除架构A,操作如下:

  1、创建用户B,再创建架构B;

  2、将架构A的权限赋给用户B,取消用户A拥有架构A的权限,删除用户A;

  3、将数据库的所有属于架构A的对象改为架构B,代码如下:

  ALTER SCHEMA [新架构名] TRANSFER 旧架构名。[数据库中的对象表或视图或存储过程]

  ALTER SCHEMA [B] TRANSFER A.[对象1]

  ALTER SCHEMA [B] TRANSFER A.[对象2]

  ALTER SCHEMA [B] TRANSFER A.[对象n]

  4、删除架构A.

  如:

  ALTER SCHEMA dbo TRANSFER danxiao1.ds_city1
