In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Per verificare che sia possibile stabilire una connessione con il database, fai clic su
Prova connessione.
Fai clic su Aggiungi connessione.
Dopo aver connesso il database SQL Server e creato una pipeline che legge dalla tabella SQL Server, puoi applicare trasformazioni e scrivere l'output in un sink.
Pipeline Studio
Apri l'istanza Cloud Data Fusion e vai alla pagina Pipeline Studio.
Espandi il menu Origine e fai clic su SQL Server.
Nel nodo SQL Server, fai clic su Properties (Proprietà).
Nel campo Nome di riferimento, inserisci un nome che identifichi l'origine SQL Server.
Nel campo Database, inserisci il nome del database a cui connetterti.
Nel campo Importa query, inserisci la query da eseguire. Ad esempio,
SELECT * FROM table WHERE $CONDITIONS.
Fai clic su Validate (Convalida).
Fai clic su Chiudi close.
Dopo aver connesso il database SQL Server e creato una pipeline che legge dalla tabella SQL Server, aggiungi le trasformazioni che preferisci e scrivi l'output in un sink.

[Create a Cloud Data Fusion instance](/data-fusion/docs/how-to/create-instance).\n3. Your SQL Server database must accept connections from Cloud Data Fusion. For security reasons, use a [private\n Cloud Data Fusion instance](/data-fusion/docs/how-to/create-private-ip).\n\n### Open your Cloud Data Fusion instance\n\n1. In the Google Cloud console, go to the Cloud Data Fusion **Instances**\n page.\n\n [Go to Instances](https://console.cloud.google.com/data-fusion/locations/-/instances)\n2. In the **Actions** column for the instance, click **View instance** to open\n the instance in Cloud Data Fusion.\n\nStore your SQL Server password as a secure key\n----------------------------------------------\n\nAdd your SQL Server password as a secure key in your Cloud Data Fusion\ninstance.\n\n1. From Cloud Data Fusion, click **System Admin**.\n\n2. Click the **Configuration** tab.\n\n3. Click **Make HTTP Calls**.\n\n \u003cbr /\u003e\n\n4. Select **PUT**.\n\n5. In the path field, enter\n `namespaces/`\u003cvar translate=\"no\"\u003eNAMESPACE_ID\u003c/var\u003e`/securekeys/password\n `.\n\n6. In the **Body** field, enter `{\"data\":\"`\u003cvar translate=\"no\"\u003epassword\u003c/var\u003e`\"}`.\n Replace \u003cvar translate=\"no\"\u003epassword\u003c/var\u003e with your SQL Server password.\n\n7. Click **Send**.\n\nThe **Response** must have status code `200` to continue.\n\nGet the JDBC driver for SQL Server\n----------------------------------\n\nYou can get the driver from the Hub or in the Pipeline Studio in Cloud Data Fusion. \n\n### Hub\n\n1. In the Cloud Data Fusion UI, click **Hub**.\n\n2. In the search bar, enter `SQL Server JDBC Driver` and select the driver.\n\n3. Click **Download**. Follow the download steps shown.\n\n4. Click **Deploy**. Upload the JAR file from the previous step.\n\n5. Click **Finish**.\n\n### Pipeline Studio\n\n1. Go to [Microsoft.com](https://www.microsoft.com/en-us/download/details.aspx?id=11774).\n\n2. Choose your download and click **Download**.\n\n3. In Cloud Data Fusion, click *menu*\n **Menu** and go to the **Pipeline Studio** page.\n\n4. Click add **Add**.\n\n5. For the driver, click **Upload**.\n\n6. Select the JAR file, located in the `jre7` folder.\n\n7. Click **Next**.\n\n8. To configure the driver, enter a **Name** and **Class name**.\n\n9. Click **Finish**.\n\nDeploy the SQL Server Plugin\n----------------------------\n\n1. In Cloud Data Fusion, click **Hub**.\n\n2. In the search bar, enter `SQL Server Plugins`.\n\n3. Click **SQL server plugins**.\n\n4. Click **Deploy**.\n\n5. Click **Finish**.\n\n6. Click **Create a pipeline**.\n\nConnect to SQL Server\n---------------------\n\nYou can connect to SQL Server from Cloud Data Fusion in Wrangler or the Pipeline Studio. \n\n### Wrangler\n\n1. In Cloud Data Fusion, click *menu*\n **Menu** and go to the **Wrangler** page.\n\n2. Click **Add connection**.\n\n An **Add connection** window opens.\n3. Click **SQL Server** to verify that the driver is installed.\n\n \u003cbr /\u003e\n\n4. Enter details in the required connection fields. In the **Password** field, select the\n [secure key you stored previously](#store_your_sql_server_password_as_a_secure_key).\n It ensures that your password is retrieved using [Cloud KMS](/kms/docs).\n\n \u003cbr /\u003e\n\n5. To check that a connection can be established with the database, click\n **Test connection**.\n\n6. Click **Add connection**.\n\nAfter your SQL Server database is connected and you've created a pipeline that\nreads from your SQL Server table, you can apply transformations and\nwrite your output to a sink.\n\n### Pipeline Studio\n\n1. Open your Cloud Data Fusion instance and go to the **Pipeline Studio**\n page.\n\n2. Expand the **Source** menu and click **SQL Server**.\n\n \u003cbr /\u003e\n\n3. On the **SQL Server** node, click **Properties**.\n\n4. In the **Reference name** field, enter a name that\n identifies your SQL Server source.\n\n5. In the **Database** field, enter the name of the database to connect to.\n\n6. In the **Import query** field, enter the query to run. For example,\n `SELECT * FROM table WHERE $CONDITIONS`.\n\n7. Click **Validate**.\n\n8. Click close close.\n\nAfter your SQL Server database is connected and you've created a pipeline that\nreads from your SQL Server table, add any desired transformations and\nwrite your output to a sink.\n\nWhat's next\n-----------\n\n- Learn how to [read data from multiple SQL Server tables](/data-fusion/docs/how-to/reading-from-sqlserver-multi).\n- Learn more about [Cloud Data Fusion](/data-fusion/docs/concepts/overview).\n- Follow one of the [tutorials](/data-fusion/docs/tutorials)."]]
