Learn about SQL models in Profiles.

This guide introduces you to the concept of SQL models in Profiles and shows how to use them in your Profiles project.

Overview

Profiles projects allows for the importing and transformation of almost any source. However, there are edge cases that cannot be completed, or are overly onerous in case of Profiles. You can use SQL models in such cases.

SQL models allow you to model data using plain or templated SQL. This is useful for complex use cases where you need to join, union, or intermediately transform data.

You can use a SQL model as an ephemeral source for ID stitcher and feature creation models, materialize it as a table or view.

Usage

You can define SQL models in the sql_model.yaml file, as shown:

models:
  - name: tracks_union_pages
    model_type: sql_template
    model_spec:
      materialization:
        output_type: view
        run_type: discrete
      single_sql: |
        {% with tracks = this.DeRef("inputs/tracks") pages = this.DeRef("inputs/pages") %}
        SELECT
          anonymous_id,
          event,
          timestamp
        FROM {{ tracks }}
        UNION
        SELECT
          anonymous_id,
          'page_viewed' AS event,
          timestamp
        FROM {{ pages }}
        {% endwith %}

Best practices

  • Verify the outputs of any SQL model in your warehouse before adding to a Profiles project.
