Cannot show requested dialog sqlmgmt как исправить

При работе с базами данных в Microsoft SQL Server Management Studio можно столкнуться с ситуацией, когда попытка открыть свойства какой-либо базы данных приводит к ошибке:

Cannot show requested dialog. (SqlMgmt)
Property Owner is not available for Database '[XXX]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights.  (Microsoft.SqlServer.Smo)

Причиной этой ошибки является невозможность определения владельца базы данных. Такая ситуация возможна, например, если владельцем базы ранее была назначена какая-либо доменная учетная запись, которая на текущий момент в домене отсутствует.

Наличие проблемы в определением владельца базы может подтвердить хранимая процедура sp_helpdb:

sp_helpdb [Имя базы данных]

Чтобы избавиться от этой проблемы, достаточно с помощью ещё одной хранимой процедуры sp_changedbowner изменить владельца базы на другую существующую учетную запись, например на встроенную учетную запись sa.

USE [Имя базы данных]
EXEC sp_changedbowner 'sa'
GO
sp_helpdb [Имя базы данных]

После этого возможность открытия диалоговой формы свойств базы данных будет восстановлена.

Know about SQL Server Error 916 and How to Fix It!

SQL Server is a relational database management system developed by Microsoft while focusing on large enterprise environment work over a network. The First version of SQL Server is 1.0 and released in the year 1989, the latest version is MS SQL Server 2016 Community Technology Preview 2.4 (CTP 2.1) released on September 30, 2015.

Problem

Accessing the SQL server database by using SQL Server Management Studio having a limited number of permissions (database read or write) may produce the SQL Server Error 916 and the message displayed on the screen is – “The server principal username is unable to access the database databasename under the current security context.”

The main problem is due to bugs present in SQL Server Management Studio that prevents the user to connect to the database and refuses to display the database list. There may be several other reasons behind the getting SQL Server Error 916.

• The user is not permitted to view the data of selected column within the database.
• The database is currently not available.
• There are multiple columns such as Size, Space available, Data Space Used, Default file group, Index Space Used, Mail host, Primary file path and user has added at least one of them to the list of Object Explorer Details.
• If the Auto Close option for the database is enabled, then Collation column cannot be retrieved by SQL Server Management Studio (SSMS).
• For a database, Collation column contains NULL.

Due to the above causes, the error message will be displayed to the user.

SQL Error 916 – Symptoms

The symptoms of the SQL Server error 916 may vary depending upon the different scenarios explained further:

Symptom 1:

In SQL Server 2008, if a user tries to expand the database folders under a node even if he is not a member of a Sysadmin fixed server role or does not have the authority to access the database. If the guest user wants to expand the database nodes, connection permission is required otherwise; the following error message will be displayed:

Failed to retrieve data for this request (Microsoft.SqlServer.Manager.Sdk.Sfc)

Additional information:

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Symptom 2:

In SQL Server 2005, if a guest user who is neither a member of a Sysadmin fixed server role, nor having the permissions is able to expand the database node but cannot view the database properties. In this case, the user will receive the following error message:

Cannot show requested dialog.(SqlMgmt)

Additional Information:

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Note: SQL Server error 916 is displayed even though the user is a database owner of that database.

Symptom 3:

A product of the Microsoft family, Microsoft Office Communications Server 2007 (OCS 2007) is affected by this issue and the services will not start even after the server is started. The following error message will be invisible in the Event Viewer:

Event Type: Error

Resolving the Symptoms

In order to view the granted permissions for the guest-user, the following command is helpful if run by a member of a Sysadmin fixed server. The query is as follows –

 SELECT prins.name AS grantee_name, perms.*
 FROM sys.database_permissions AS perms
 JOIN sys.database_principals AS prins
 ON perms.grantee_principal_id = prins.principal_id
 WHERE prins.name = ‘guest’ AND perms.permission_name = ‘CONNECT’;
