* Se aplica a los clientes de las ediciones profesional y empresarial de Alteryx One en las versiones 2025.1 o posteriores de Designer.

Utiliza la herramienta Salida de flujo de datos para transmitir datos desde un flujo de trabajo En-BD hacia Alteryx Designer.

Las herramientas de la categoría En base de datos permiten combinar y analizar grandes conjuntos de datos sin tener que mover la información fuera de la base de datos, y pueden proporcionar importantes mejoras de rendimiento en comparación con los métodos de análisis tradicionales. Para obtener más información sobre la categoría de herramientas En base de datos, consulta la descripción general.

Configurar la herramienta

Use the Configuration window to customize the Data Stream Out tool.

  • Advanced Query Options: Use this section to define Pre- and Post-SQL statements to execute. Pre- and post-SQL statements are compatible with the Bulk Loaders, OCI, ODBC, and OLE DB technologies.

    To configure your SQL statements...

    1. Use the 3-dot menu associated with either the Pre or Post Statement fields to launch the Configure Pre/Post SQL Statements window, which includes the SQL Editor and Stored Procedures tabs.

    2. Next, define SQL statements as needed:

      • Pre-SQL Statement: Define a SQL statement to execute before the in-database execution.

      • Post-SQL Statement: Define a SQL statement to execute after the in-database execution.

    3. To configure Pre-SQL and Post-SQL statements...

      • Use the SQL Editor tab to define a SQL statement to execute before/after the In-DB execution. When the workflow runs, the Results window displays messages to show that the tool is executing SQL statements, along with a label (PreSQL/PostSQL).

        • All SQL statements are sent directly to the database. Pre-SQL statements do not return data. While SQL can return data, Designer doesn't do anything with it.

        • If there are multiple streams of In-DB tools, there is no guaranteed order of execution between different streams. The Results window displays the order.

      • Use the Stored Procedures tab to select and configure a stored procedure call for your database. You can select a Parameter and set a Value for your stored procedures if needed. All stored procedures are sent directly to the database.

        • If a stored procedure is executed successfully, it returns any necessary status messages or warnings in the Results window.

        • If a stored procedure returns data, Designer does not return it anywhere. The data is not displayed in the Results window.

        Importante

        Stored procedures are supported for these connections:

        • SQL Server for ODBC and Bulk Writer

        • Oracle for ODBC Only

    4. Select OK when you're finished or Cancel to return to the tool configuration window.

  • Sort records before streaming out: This is an optional setting. When checked, the incoming data is sorted by the field specification below.

    • Nombre : selecciona el campo para ordenar.

    • Ordenar : elige entre Ascendente o Descendente.

    • Utiliza las flechas arriba y abajo para cambiar el orden, y el botón “-” para eliminar un campo.
