BAM部署视图失败 - OLE DB or ODBC error: Cannot open database "BAMStarSchema". login failed 42000.
错误描述
今天在部署BAM视图时遇到如下错误，找了很久终于找到原因，原来是数据库用户角色设置的问题，BAMStarSchema数据库的用户没有”db_datareader”角色导致无法读取该数据库当中的数据。

解决方法
我们可以使用T-SQL语句来修复该数据库中的用户角色设置，为该用户添加对其数据库的“db_datareader”角色。在我的机器上，数据库是运行在DemoDomain/SQL_Service这个账户下的，使用如下脚本启用该用户的'db_datareader'角色，另外你也可以通过SQL Management Studio用鼠标点击配置的方式做同样的操作。
USE BAMStarSchema EXEC sp_addrolemember 'db_datareader', 'DEMODOMAIN/SQL_SERVICE'
