I found this thread: Failed to generate scripts for Sql Azure database: "Getting the list of objects from : failed"
but I cannot use: http://cloudservices.red-gate.com/
Try using third party tools for SQL Server that are able to work with Azure. I think SQL Compare from Red-Gate had the ability to work with SQL Azure but I’m not 100% sure. You can always use it in trial mode to get the job done…
SQL Azure Migration wizard might be an option for you as well.

some strange SSMS behaviour annoyed me for the last few days.
I'm using EF Core 5 Code First and trying to create a test database with EnsureCreated(). The code runs fine and database appears on my local server. But when I try to expand Tables in SSMS I get following error:
I'm using mssql docker container which is configured for German language (MSSQL_LCID: 1031).
Also, we have production database dumps that I can restore on my local machine and get everything work fine.
Here are default server and database collation which I found in properties:
server: SQL_Latin1_General_CP1_CI_AS
database from dump: Latin1_General_CI_AS
database from EnsureCreated(): Latin1_General_CI_AS
So as you see collations for each databases are the same. But I don't get conflict on restored one!

Seems like it comes from view all_columns. I also can't do any select from this system view nor event see its columns.
I'm new to Postgres and using npgsql as the provider to EF6. Just to provide some context, I've recently migrated our SQL Server to Aurora Postgres using the AWS DMS. That seems to be all good; I can see data and tables, etc...Now, I'm trying to hook up our application (in C# using EF6) to switch over to the Postgres DB. I've gone through all the steps to setup npgsql and npgsql EF provider, and making a new additional db context to connect to the Postgres DB. All seems good at this point.
I decided to do a simple EF query to fetch.
var courses = context.Courses.FirstOrDefault();
I got this exception:

I have tried starting the job from SQLCMD as well. Same results.
I have tried Detach/Attach method as well. That went through fine, however, that is not a desired option as it leaves the DB offline for the transfer's duration.
I have admin rights on the server(Windows) and the instance as well.
Executing the package(.dtsx file using Package Execution Utility) outside SSMS gives the same error.
I have created an empty database with only one table in it. Same error happens.
Please help..

This has been resolved with applying the January 2018 CU, even though this fix is NOT documented there.
I'm running the SQL Server Copy Database Wizard.
Of note is that the Operator is NT AUTHORITY\SYSTEM, which I thought should have the authority to run whatever it wants.
How can we grant sufficient privileges to NT AUTHORITY\SYSTEM? I have already tried:
GRANT EXECUTE ON xp_regread TO public
GRANT EXECUTE ON xp_regread TO [NT AUTHORITY\SYSTEM]
And running the following shows that it worked.
SELECT
grantee_principal.name AS [Grantee]
, prmssn.permission_name
FROM
sys.all_objects AS xproc
INNER JOIN sys.database_permissions AS prmssn ON prmssn.major_id=xproc.object_id AND prmssn.minor_id=0 AND prmssn.class=1
INNER JOIN sys.database_principals AS grantee_principal ON grantee_principal.principal_id = prmssn.grantee_principal_id
WHERE
(xproc.type='X')and(xproc.name=N'xp_regread' and SCHEMA_NAME(xproc.schema_id)=N'sys')
Output:
Grantee permission_name
public EXECUTE
NT AUTHORITY\SYSTEM EXECUTE

This is the tool we need to use, because we don't have access to the remote server, and because the Import-Export Wizard failed.
You might need to add the account to the sysadmin server role, which allows a member to perform every activity.
For 2008r2, execute this command:
EXEC sp_addsrvrolemember 'NT AUTHORITY\SYSTEM', 'sysadmin';
This is a common error encountered when attempting to update the registry from SQL Server, and there are some weird and non-obvious pathing issues in newer versions such as SQL Server 2017.
The error is not due to security within SQL Server, but instead Windows security related to the permissions on the registry keys as relates to the users under which specific SQL Server processes are running.
For instance, to execute MSSQL related registry commands from SQL Server, the system group NETWORKSERVICE needs full control on the relevant registry path. This is because SQL Agent (by default) runs as a user in that system group.
For SQL Server settings, the Registry path is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
As an example, the command in SQL Server to set the log file size limit to be 1024 KB is as follows:
USE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE',
N'SOFTWARE\Microsoft\Microsoft SQL Server\MSSQLServer',
N'ErrorLogSizeInKb', REG_DWORD, 1024
GO
Also note the truncated path above. The actual full registry path (for SQL2017) is as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQLServer
The xp_instance_regwrite SQL Server command automatically injects the version key into the path. For SQL Server 2017 that key is MSSQL14.MSSQLSERVER.
