在分配数据库登录用户的数据库访问权限的时候出现这种错误,如果选中某一个数据库的任何一个角色就会出现这个错误

错误21002:[sql-dmo]用户***已经存在错误
此错误的原因多是因为将MSSQL备份移植到另一服务器还原时出现。
主要原因是原来的备份还原时保留了原用户的信息，导致产生孤立用户
解决方法：
1.打开mssql企业管理器→数据库→展开出问题的数据库如"mydb"→"用户"→在右侧窗口中选择出问题的用户名如:"***"→右击鼠标→删除
2.企业管理器→安全性→登录→在右侧窗口中选择出问题的用户名如:"***"→属性→数据库访问→点选"mydb"→勾选下方的"public"和"db-owner"→确定
