Using sqlc in CI/CD

If your project has more than a single developer, we suggest running sqlc as part of your CI/CD pipeline. The two subcommands you’ll want to run are diff and vet.

sqlc diff ensures that your generated code is up to date. New developers to a project may forget to run sqlc generate after adding a query or updating a schema. They also might edit generated code. sqlc diff will catch both errors by comparing the expected output from sqlc generate to what’s on disk.

sqlc vet runs a set of lint rules against your SQL queries. These rules are helpful in catching anti-patterns before they make it into production. Please see the vet documentation for a complete guide to adding lint rules for your project.

General setup

Install sqlc using the suggested instructions.

Create two steps in your pipeline, one for sqlc diffand one for sqlc vet.

GitHub Actions

We provide the setup-sqlc GitHub Action to install sqlc. The action uses the built-in tool-cache to speed up the installation process.

GitHub Workflows

The following GitHub Workflow configuration runs sqlc diff on every push.

name: sqlc
on: [push]
jobs:
  diff:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - uses: sqlc-dev/setup-sqlc@v3
      with:
        sqlc-version: '1.19.0'
    - run: sqlc diff

The following GitHub Workflow configuration runs sqlc vet on every push. You can use sqlc vet without a database connection, but you’ll need one if your sqlc configuration references the built-in sqlc/db-prepare lint rule.

name: sqlc
on: [push]
jobs:
  vet:
    runs-on: ubuntu-latest
    services:
      postgres:
        image: "postgres:15"
        env:
          POSTGRES_DB: postgres
          POSTGRES_PASSWORD: postgres
          POSTGRES_USER: postgres
        ports:
        - 5432:5432
        # needed because the postgres container does not provide a healthcheck
        options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5
    env:
      PG_PORT: ${{ job.services.postgres.ports['5432'] }}

    steps:
    - uses: actions/checkout@v3
    - uses: sqlc-dev/setup-sqlc@v3
      with:
        sqlc-version: '1.19.0'
      # Connect and migrate your database here. This is an example which runs
      # commands from a `schema.sql` file.
    - run: psql -h localhost -U postgres -p $PG_PORT -d postgres -f schema.sql
      env:
        PGPASSWORD: postgres
    - run: sqlc vet
