What is the primary function of the 'dbt compile' command?

The primary function of the 'dbt compile' command is to generate compiled SQL files without executing them. When this command is executed, dbt processes the project's models, macros, and configurations, converting them into SQL statements that can later be run against the database. This allows users to review the generated SQL to verify that it matches their expectations before actually executing any operations against the database.

This step is particularly crucial during the development process, as it helps identify syntax errors or logical problems in SQL generation without the risk of running potentially faulty SQL against a live database. The compiled SQL files are not executed; they are simply created, enabling a clear understanding of what will happen if the models are run.

Focusing on this function helps practitioners ensure that their dbt models are correctly configured and ready for execution when they choose to do so.
