I'm trying to export a database from a CloudSQL SQL Server Express Database, that is currently attached on a user other than sqlserver, and import it on a new CloudSQL SQL Server Standard Database. While I can export/import normally with BAK files, I'm unable to create a new user on the destination database and grant it the db_owner on the imported schema, everything always goes only to the sqlserver user. Can someone help me out?
Best regards.
You haven't mentioned what have you tried, for creating users and what output you received when you tried that.
But have you tried creating the user using gcloud cli? gcloud sql users create
https://cloud.google.com/sdk/gcloud/reference/sql/users/create
You can assign the above user to access a specific database once it has been created using the command above.
If the new Standard Database is on a new Cloud SQL instance, you might be using the new default MASTER database. By design, the "db_owner" role cannot be attributed there, so you may create a new database and grant the role on that new one instead.

I have created 2 azure security groups (Read-SQL and the second is Write-SQL) in order for them to login into multiple Azure SQL servers via SSMS using their Azure AD identity based on their group membership in order to access multiple databases on those services.
First of all I have configured an admin group on the SQL Server in our Azure tenant.
I have connected to the SQL via SSMS using my credentials and so far so good.
After that I opened a query and typed in master database
CREATE USER [SQL-READ] FROM external provider
ALTER ROLE db_datareader ADD MEMBER [SQL-READ];
(Did the same thing for Write-SQL)
only the user is created and no permission given with an error saying the user does not exist or I don't have permission.
I have Azure global administrator permission in Azure and I don't know why I get this error.
In the bottom line I would like that Read-SQL and Write-SQL will be able to login in to the SQL Server and have access to all databases within it as well as giving Read-SQL reading permissions and to Write-SQL writing permission.
I read a few Microsoft articles but I got even more confused since I don't know if I need to create a login or create a user or a contained user.
Please help
Thank you

Read the following articles but only partial success.

Whether you should create a login, user or contained user will depend on your access and security requirements. However, in Azure SQL Database, users are created per database. So, you can create the login in the master database and then you need to create the associated user in each database on that SQL Server.
This documentation gives more information on creating logins, users and contained users for Azure SQL Database.
I'm trying to determine who created a database in my SQL Server instance. The .trc logs seem to have been purged and I can't locate a backup of them. I know when the database was created and have found the .bak file that was used to create the database, but I can't determine WHO created it.
Any other ideas how I can figure this out? (SSMS schema history report also doesn't go back far enough)
Based on the following article:
There is no dbo concept for server scope securables. They are always owned by the login that created them, no matter of any server roles that the login might be a member of.
So by default, the database owner is the one who created the database, but you have to make sure that no one changed this property:
To check the database owner, in SQL Server management studio, Right click on the database and in the Properties window >> General Tab >> check the owner property:
I created a new SQL server with a database in Azure and after logging in with the admin account I added a new user that I wanted to only have access to one database.
In SSMS I right clicked on mynewdatabase database and selected New Query.
I executed
CREATE USER mynewuser WITH PASSWORD ='good password here';
ALTER ROLE db_owner ADD MEMBER mynewuser ;
Now after logging in as mynewuser I can still see the master database.
The question is how do I restrict mynewuser to only access mynewdatabase?
I'm sure this is something basic.
In SQL Server, including Azure SQL DB, all users can can see all system databases in sys.databases. This is not the same as being able to connect to them or run queries in them. This does not disclose any sensitive information as these are system databases and whether you saw them listed or not you would know they were there. See https://msdn.microsoft.com/en-us/library/ms178534.aspx#Anchor_0.
Based on the steps you describe, you have created a contained user that should not be able to connect to the master database or run queries in Azure SQL DB.
I tried to migrate a SQL Server database by Export Data-tier Application (.bacpac file) from an Amazon RDS instance to other, but import didn't succeed. So now I want to delete the database (which is empty), when I try to:
DROP DATABASE mydatabase;
I get the error:
Cannot drop the database 'mydatabase', because it does not exist or
you do not have permission
Some context:
I've tried using SQL Server Management Studio, and choosing close connections: same error.
I'm logged as master user.
I can create and drop other databases, but not this one.
I just have these effective permissions on this database: CONNECT, SHOWPLAN, VIEW DATABASE STATE, VIEW DEFINITION (don't know why or how is this possible).
Any help is greatly appreciated!
I ran into this same issue. After trying to restore a database via SSMS using a .bacpac, it fails and leaves you with a database that you appear to not have permissions to drop.
A workaround, is to use the rdsadmin rename function to rename it to something else, which then seems to fix the permission issue and allows you to drop it.
EXEC rdsadmin.dbo.rds_modify_db_name N'<OldName>', N'<NewName>'
Then just drop the DB. Hope that helps someone else in the same predicament.
This is the answer for an old thread but who knows, it might help someone having the same issue.
I ran into the same problem, but in my case, my database was in an offline mode. If the database is in offline mode, it won't allow you to drop it with the drop command. first, you should bring the database back online by running this sp and then execute the drop table command.
EXEC rdsadmin.dbo.rds_set_database_online databasename
If your database is in a Multi-AZ deployment, then you need to run this command to drop those databases:
EXECUTE msdb.dbo.rds_drop_database N'DBName'
Sounds like your not a member of the correct role.

Permissions
A DAC can only be deleted by members of the sysadmin or serveradmin fixed server roles, or by the database owner. The built-in SQL Server system administrator account named sa can also launch the wizard.
https://msdn.microsoft.com/en-us/library/ms178613.aspx
Permissions
SQL Server - Requires the CONTROL permission on the database, or ALTER ANY DATABASE permission, or membership in the db_owner fixed database role.
Azure SQL Database - Only the server-level principal login (created by the provisioning process) or members of the dbmanager database role can drop a database.
Parallel Data Warehouse - Requires the CONTROL permission on the database, or ALTER ANY DATABASE permission, or membership in the db_owner fixed database role.
Is it possible to set up a default set of role mappings for Microsoft SQL Server (2008 R2 for instance) that apply to subsequent databases?
Example: Whenever I create a new database on the server, I want it to map db_owner to a login group called Group_A and db_datareader to a group called Group_B.
The databases are created by a 3rd party application, so doing it in the CREATE statement is not enough. What I hope for is to set a default behaviour for the server itself.
Every new database is created as a copy of the model database on the SQL server. So when you do the mapping the the MODEL db every new DB should replicate that. I haven't tried that with roles and groups but you can try it and let me know whether it works...
