Question

我的Django应用通常可以在SQLite3上运行，但是这次我不得不将其转换为使用SQL Server。在测试服务器上，一切正常，但是当我的朋友将此数据库复制到客户端的服务器时，出现错误：

(norm)esd@server:~/Desktop/norm/myproject> python manage.py runserver

django.db.utils.ProgrammingError: ('42S02', "[42S02] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Invalid object name 'django_migrations'. (208) (SQLExecDirectW)")

尝试迁移，运行服务器等时出现错误。

我发现当我直接从Linux（sqlcmd）登录数据库时，我也无法执行“正常”选择，例如

SELECT * FROM django_migrations;

今天我发现我可以这样使用它：

SELECT * FROM db_owner.django_migrations;

这将结束我的问题，但是如何告诉Django模型以这种方式使用它或修复数据库？在测试数据库（其他服务器，相同的SQL Serverversion等）上，一切都很好。当我尝试从没有db_owner前缀的表中进行选择时，出现此错误：

django.db.utils.ProgrammingError: ('42S02', "[42S02] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Invalid object name 'django_migrations'. (208) (SQLExecDirectW)")

Answer 1

正如Ivan所说，我更改了所有表以使用dbo模式而不是db_owner，一切开始正常工作！我做到了

ALTER SCHEMA dbo TRANSFER db_owner.tableName;

在数据库中的每个表上。

SQL Server在客户端数据库的选择中使用db_owner前缀
