Alaister YoungandAlaister Young 3036bb103b [FE-3134] fix(studio): handle ALTER TABLE IF EXISTS in RLS detection (#45493)
The SQL Editor was warning about missing RLS even when the same query
enabled it, if the user wrote `ALTER TABLE IF EXISTS ...`. The parser
regex didn't recognise `IF EXISTS` and was capturing `IF` as the table
name, so the RLS event never matched the `CREATE TABLE`.

**Changed:**
- `ALTER TABLE` regex in `sql-event-parser.ts` now accepts the optional
`IF EXISTS` and `ONLY` modifiers, matching Postgres's `ALTER TABLE [ IF
EXISTS ] [ ONLY ] name` grammar.

**Added:**
- Unit tests for `IF EXISTS`, `ONLY`, and both combined.
- Regression test in `SQLEditor.utils.test.ts` using the customer's
exact SQL.

## To test

1. Open the SQL Editor and paste:

```sql
CREATE TABLE IF NOT EXISTS public."Conversations" (id int8 primary key);
ALTER TABLE IF EXISTS public."Conversations" ENABLE ROW LEVEL SECURITY;
```

2. Hit Run – the "table will not have RLS" warning should **not**
appear.
3. Sanity check: a `CREATE TABLE` without any matching `ENABLE ROW LEVEL
SECURITY` still triggers the warning.

## Summary by CodeRabbit

* **Tests**
* Added comprehensive test coverage for Row Level Security detection
across different SQL syntax patterns and clause combinations

* **Bug Fixes**
* Enhanced Row Level Security detection capabilities in the SQL editor
by extending support for additional ALTER TABLE statement syntax
variations, improving the accuracy and completeness of security
configuration recognition

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the contributing checklists to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v20
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
