dbt (Data Built Tool) Commands Cheat Sheet
Master DBT with this cheat sheet: Quick commands guide for efficient data build tool usage and streamlined workflows.
What is dbt?
As a data engineer, you need to be able to transform raw data into meaningful insights that can inform business decisions. dbt (Data Build Tool) is an open-source tool that allows you to build and manage data transformation pipelines in your data warehouse. dbt makes it easy to write modular, testable, and reusable SQL code that can be easily maintained and updated over time. In this article, we'll provide a cheat sheet for data engineers who are new to dbt or looking to expand their dbt skills. We'll cover some of the most commonly used dbt commands and provide sample code snippets that can be used as a reference for writing dbt code. By following these examples and referencing the dbt documentation, you can create robust and efficient data transformations in your data warehouse.
Basic and common commands:
These commands are just a subset of the dbt commands available, but they cover most of the basic functionality of dbt. You can find more information about these commands and additional commands in the dbt documentation.
Additionally, here are some sample code snippets that can be used as a reference for writing dbt code:
1. Creating a new model:
2.Using a Macro:
3.Defining a test:
4.Defining a snapshot:
These snippets demonstrate some basic dbt functionality, including creating a model, using a macro, defining a test, and defining a snapshot. You can customize these snippets to fit your specific use case, and use them as a starting point for your own dbt code.
5. Using a materialized view:
6. Defining custom operation:
These snippets demonstrate more advanced functionality, including using a materialized view and defining a custom operation. The materialized view example shows how to define an incremental strategy and a unique key for a materialized view, which can help improve performance and reduce duplication in your data warehouse. The custom operation example shows how to define a custom macro that can be used to execute a SQL query and return a result, and how to call that macro from a dbt model.
Overall, these cheat sheet snippets should provide a good starting point for data engineers who are new to dbt or looking to expand their dbt skills. By following these examples and referencing the dbt documentation, you can create robust and efficient data transformations in your data warehouse.
