SQL Server 2008 R2 中不能删除复制(replication) 的解决方法

错误描述：

Msg 15517, Level 16, State 1, Procedure sp_replcmds, Line 1

Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.

将 publisher 的数据库sp_changedbowner 'sa' 然后再执行删除，就能解决问题了
