Nesta página, descrevemos como ler várias tabelas de um banco de dados do Microsoft SQL Server usando a fonte de várias tabelas.
Use a fonte de várias tabelas quando quiser que o pipeline leia a partir de várias tabelas. Se você quiser que seu pipeline leia a partir de uma única tabela, consulte Como ler uma tabela do SQL Server.
A origem de várias tabelas gera dados com vários esquemas e inclui um campo de nome da tabela que indica a tabela de onde vieram os dados. Ao usar a fonte de várias tabelas, use um dos coletores de várias tabelas, BigQuery Table ou arquivo multiGCS para criar um anexo da VLAN de monitoramento.

Ao usar o Cloud Data Fusion, você usa o console Google Cloud e a IU separada do Cloud Data Fusion. No console Google Cloud , é possível criar um projeto Google Cloud e criar e excluir instâncias do Cloud Data Fusion. Na interface do Cloud Data Fusion, é possível usar as várias páginas, como o Studio ou o Administrador, para acessar os recursos dele.
No console Google Cloud , acesse a página do Cloud Data Fusion.
Para abrir a instância no Cloud Data Fusion Studio, clique em Instâncias e em Ver instância.
Armazenar a senha do SQL Server como uma chave segura
Adicione a senha do SQL Server como uma chave segura para criptografar na instância do Cloud Data Fusion. Posteriormente neste guia, você garantirá que sua senha seja recuperada usando o Cloud KMS.
