How SqlGuard works

SqlGuard turns a declarative YAML spec into deterministic CI pass/fail results for SQL behavior.

Step 1 — Declare expectations (YAML) spec

Describe what must remain true about your database behavior (shape, invariants, permissions). 

# sqlguard.yaml (excerpt)
suites:
  - name: Orders schema
    connection: main
    checks:
      - type: queryContract
        sql: SELECT * FROM Orders
Step 2 — Run in CI (GitHub Actions) execute

Add SqlGuard as a step in your CI workflow. Output is deterministic and machine-readable. 

# .github/workflows/ci.yml
- name: SqlGuard validation
  run: |
    sqlguard validate-spec --spec sqlguard.yaml
    sqlguard run --spec sqlguard.yaml --out report.json
Step 3 — CI sees pass/fail gate

Your CI treats it like tests. Exit codes follow standard conventions (0 = pass, non-zero = fail). 

✔ Orders schema
  ✔ queryContract: Orders columns unchanged

Test Suites: 1 passed, 0 failed
Exit code: 0

Designed for platform and backend teams

Correctness

  • Catch unintended behavior changes early
  • Deterministic results for CI

Security

  • Permission regression checks
  • No secrets in output (redaction)

Pragmatic

  • No SaaS, no agents, no dashboards
  • Public docs + private implementation

What SqlGuard is (and isn’t)

It is

  • A deterministic CI gate for SQL Server / Azure SQL changes
  • Designed for CI pipelines (GitHub Actions, Azure DevOps, Jenkins)
  • Focused on correctness, security checks, and regression prevention

It isn’t

  • A hosted SaaS service
  • A dashboard or monitoring/observability agent
  • A general-purpose query runner or ORM migration tool
