Azure上的SQL Server中的用户'san'登录失败

Question

I keep getting an error

Login failed for user 'san'

while using Azure database from Web API with Entity Framework.

Here is the screen shot of SSMS. I am able to access the database from SSMS, but not from the Web API database call.

I tried to create a new login and user but getting an error

User already exists

Here is the connection string

"DefaultConnection": "Server=tcp:fetessbird.datatable.windows.net,1433;Initial Catalog=Falcon;Persist Security Info=True;User ID=san;Password=*****;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"

I am able to access the database from SSMS not from the webapi

Answer 1

Connect to the Falcon database using SQL Server Management Studio and run the following statements.

CREATE USER San FROM LOGIN San;
GO
EXEC sp_addrolemember 'db_owner', 'San';

Answer 2

You just create a LogIn named San on the server, what you need now is to create a user related to this LogIn in the Flcon database, you should give it permissions to the db.

Go to Falcon -> Users -> RightClick -> New user

then follow the wizard.

Update:

To create the user:

CREATE USER San FOR LOGIN San WITH DEFAULT_SCHEMA = Falcon;  
GO 

Then you can give it rights as(if you already have the user the just give it rights):

EXEC sp_addrolemember N'db_owner', N'San' 
GO

Answer 3

As from your screenshot the login san is created and valid on the SQL Server but you haven't given any permissions to the database you are connecting to from the API. The login san it's not an user on the database you want to access.
