1）如果已經有一個登錄「用戶1」，那麼我通過調用CreateDatabaseUser函數問題在使用SMO
2創建爲數據庫「DB1」用戶「USER1」）否則在SqlServer的創建用戶，創建一個方法（2）使用CreateServerLogin創建用戶'user1'作爲'db1'使用CreateDatabaseUser
方法（2）拋出一個異常在 newUser.Create(); in CreateDatabaseUser
說，Microsoft.SqlServer.Management.Smo.FailedOperationException: Create failed for User 'user1'. ---> Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. --- > System.Data.SqlClient.SqlException: '[user1]' is not a valid login or you do not have permission.
可能是什麼問題？
private static Login CreateServerLogin(Server server, string database, string login, string password)
{
var newLogin = new Login(server, login)
{
LoginType = LoginType.SqlLogin,
DefaultDatabase = database,
PasswordPolicyEnforced = false
};
newLogin.Create(password);
return newLogin;
}
private static User CreateDatabaseUser(Database database, string user, string login)
{
var newUser = new User(database, user) { UserType = UserType.SqlLogin, Login = login };
newUser.Create();
newUser.AddToRole("db_owner");
return newUser;
}
