TSQL para asignar usuario a la base de datos

Question

Así que no puedo usar el administrador de empresa para hacer esto ... Si fuera así, ni siquiera estaría haciendo esta pregunta. Así que me pregunto si hay una manera a través de TSQL para ejecutar un comando que asigna un usuario a una base de datos en particular y les otorga permisos 'propietario'.

Gracias ...

Answer 1

Cambio de base de datos por defecto de un inicio de sesión:

alter login <loginname> with default_database = <dbname>; 

Crear un usuario en una base de datos para una entrada dada:

use <dbname>; 
create user <username> from login <loginname>; 

Hacer una miembro de usuario del grupo db_owner:

use <dbname> 
exec sp_addrolemember 'db_owner', '<username>'; 

Hacer un inicio de sesión 'dbo' de una base de datos:

alter authorization on database::<dbname> to <loginname>; 

Answer 2

CREATE USER y sp_addrolemember

Answer 3

Oficialmente, que desea crear un usuario de base de datos que está asignado a un inicio de sesión. Para hacer eso, usaría:

Create User <username> For LOGIN <loginname> 

Esto obviamente requiere que el inicio de sesión exista. Después de que usted entonces llamar:

exec sp_addrolemember 'db_owner', <username> 

Esto supone que la cuenta con la que se está conectando a la base de datos tiene privilegios para agregar miembros a la función db_owner.

Answer 4

USE [YourDB] 
GO 
CREATE USER [xyx] FOR LOGIN [xyz] 
GO 
ALTER USER [xyz] WITH DEFAULT_SCHEMA=[dbo] 
GO 
EXEC sp_addrolemember N'db_owner', N'xyz' 
GO 

Answer 5

Por supuesto, normalmente, no desea conceder permisos de propietario a los usuarios. Esto es lo que aquellos de nosotros en el mundo de DBA llamamos "Una cosa mala".

usando: crear en el servidor SQL de sesión con permisos de administrador de sistemas: AdminAPI

 SQLserverAPI.CreateNewDatabaseSqlserver("yourServer.cloudapp.net,1433", "databaseName", "AdminAPI", "password*"); 
     SQLserverAPI.CreateLoginInSqlServer("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "My_Login", "password*");
