6. Jinja Templating in dbt In the above DAG, int_users model is the product of stg_users and stg_user_groups. We need to specify this relationship in our project, otherwise dbt run executes all models alphabetically, which means int_users goes first. This will result in an error as its...
Macros (宏编程)是dbt的高级功能,可以更方便的拼接各种SQL组件,并可以组合成一些宏函数,从而组装成无比复杂的程序。 可以参考https://docs.getdbt.com/tutorial/using-jinja来了解dbt中Macros的使用场景。 比如,BI等数据分析中一个常用的场景是 pivot 操作。如果不使用宏,那么,SQL可能会写为: selectorder_id,sum...
这就是 dbt 上场的机会 —— dbt 提供的是一个面向数据转换(ETL 的 T)的开发框架。它的核心基于Jinja模板语言,使得 SQL 也可以像函数一样接受参数,并被多处复用。 {% set payment_methods = ["bank_transfer", "credit_card", "gift_card"] %} select order_id, {% for payment_method in payment_m...
Jinja can be used in any SQL in a dbt project, includingmodels,analyses,tests, and evenhooks. Ready to get started with Jinja and macros? Check out thetutorial on using Jinjafor a step-by-step example of using Jinja in a model, and turning it into a macro!
Jinja & Macros dbt uses theJinjatemplating language, which makes a dbt project an ideal programming environment for SQL. With Jinja, you can do transformations that are not normally possible in SQL, like using environment variables or macros — abstract snippets of SQL, analogous to functions in...

本教程将引导你了解如何在本地创建、运行和测试 dbt 模型。 还可以将 dbt 项目作为 Azure Databricks 作业任务运行。 有关详细信息,请参阅在 Azure Databricks 作业中使用 dbt 转换。 开始之前的准备工作 要遵循本教程,必须先将 Azure Databricks 工作区连接到 dbt Core。 有关详细信息,请参阅连接到 dbt Core。
Fleshed out themodel jinja variable page, which originally lacked conceptual info and didn’t link to the schema page. Added a newQuickstarts landing page. This new format sets up for future iterations that will include filtering! But for now, we are excited you can step through quickstarts ...
O dbt-utils oferece uma ampla variedade de macros pré-criadas para operações SQL comuns usando modelos Jinja, como junções, agregações, filtragem e muito mais. Essas macros são padronizadas para garantir a consistência entre os projetos e reduzir a necessidade de codificaç...
