Database connection tool

The Connect In-DB tool creates an in-database connection in a workflow. Use the tool to connect to a new or existing connection.
In-Database enables blending and analysis against large sets of data without moving the data out of a database and can provide significant performance improvements over traditional analysis methods. For more about the In-Database tool category, see In-Database Overview.
Configure the tool
- In the Configuration window, click the Connection Name drop-down arrow and selection an option:
- Manage Connections: Create a new connection or use an existing connection.
- Open File Connection: Browse to a saved database connection file.
- Once the connection is configured, Table or Query displays the name of the selected database table.
- (Optional) Click Query Builder to select tables and construct queries. See Choose Table or Specify Query Window.
- Click the Connection Name drop-down arrow and click Manage Connections.
- Click Data Source and select a source. See In-Database.
- Click Connection Type and select type.
- User: Create a connection that only you can use.
- System: Create a connection that can be shared. Open Alteryx Designer as an administrator on your computer. This option is only for Designer Admin.
- File: Saves a database connection as an .indbc file so it can be packaged with a workflow. If this option is selected, a Connection File path location must be specified in order to save the file.
- Click Connections and select an existing connection from the list, or click New.
- In Connection Name, type a name for the connection.
- Click Password Encryption and select an encryption option:
- Hide: Hide the password using minimal encryption.
If you plan to schedule this workflow to run on any machine other than your computer, select Hide. See Schedule Workflows.
- Encrypt for Machine: Any user on the computer will be able to fully use the workflow.
- Encrypt for User: The logged in user can use the workflow on any computer.
- Allow Decryption of Password: Decrypts the password and passes it in the metadata. This option is only used in conjunction with In-DB predictive tools.
- On the Read tab, click Driver and select an option or leave as default.
- Click the Connection String drop-down arrow and select New database connection.
See ODBC and OLEDB Database Connections for more information on creating ODBC and OLEDB connections. See Supported Data Sources for more information on a specific data platform.
- Click the Write tab.
- Click Driver and select a driver or leave as default.
- In Connection String, type or paste a connection string.
- HDFS Connections
- Click the Connection String drop-down arrow and select New HDFS Connection.

- Knox Gateway: A user name and password are required.
- Use a trusted certificate when configuring Knox authentication. Alteryx does not support self-signed certificates.
