project_name

Changelog

The project_name context variable returns the name for the root-level project which is being run by dbt. This variable can be used to defer execution to a root-level project macro if one exists.

Example Usage

redshift/macros/helper.sql
/*
This macro vacuums tables in a Redshift database. If a macro exists in the
root-level project called `get_tables_to_vacuum`, this macro will call _that_
macro to find the tables to vacuum. If the macro is not defined in the root
project, this macro will use a default implementation instead.
*/
