Estou criandoMicrosoft SQL Server Management Studio Ferramenta de automação usando python. O problema é que não consigo selecionar oChild_treeBanco de dados (Northwind) Está selecionando oParent_tree(Bancos de dados). Preciso fazer muito mais, clicando na opção child_tree (Northwind) com o botão direito do mouse (Ex. Tarefas-> backup). Ajude-me a fazer o melhor código de automação. Desde já, obrigado.
