Production & Staging Database Query Skill

Query the Ballee production and staging databases safely using credentials from .env.local (with automatic 1Password fallback and caching).

When to Use This Skill

Use this skill when:

• Debugging production/staging data issues
• Verifying data exists on production or staging
• Investigating user-reported bugs that require database inspection
• Checking RLS policy behavior in production/staging
• Analyzing production data for support requests
• Applying hotfix migrations to production or staging

Supabase Project Reference

Ballee uses two separate Supabase databases for production and staging environments.

Connection Pooler Hostnames

Important: Use aws-1-eu-central-1 (not aws-0) for reliable connections.

Production:

• Session mode: aws-1-eu-central-1.pooler.supabase.com:5432
• Database user: postgres.csjruhqyqzzqxnfeyiaf

Staging:

• Session mode: aws-1-eu-central-1.pooler.supabase.com:5432
• Database user: postgres.hxpcknyqswetsqmqmeep

Credential Management

Environment Variables (Primary - Preferred)

Credentials are stored in apps/web/.env.local:

1Password (Fallback - Auto-cache)

If environment variables are not set, credentials will be fetched from 1Password and cached to .env.local:

Prerequisites

• PostgreSQL client tools installed (psql)
• Credentials in .env.local OR 1Password CLI installed and authenticated (op whoami)

Quick Reference Commands

Production Database

# Load password from .env.local (or fetch from 1Password and cache)
source apps/web/.env.local 2>/dev/null
if [ -z "$SUPABASE_DB_PASSWORD_PROD" ]; then
  SUPABASE_DB_PASSWORD_PROD="$(op item get kuyspxxlyi2mxg7nfeb6dm3pje --fields notesPlain --reveal)"
  echo "SUPABASE_DB_PASSWORD_PROD=$SUPABASE_DB_PASSWORD_PROD" >> apps/web/.env.local
fi

# Connect to production
PGPASSWORD="$SUPABASE_DB_PASSWORD_PROD" psql \
  "postgresql://postgres.csjruhqyqzzqxnfeyiaf@aws-1-eu-central-1.pooler.supabase.com:5432/postgres"

# Execute single query on production
PGPASSWORD="$SUPABASE_DB_PASSWORD_PROD" psql \
  "postgresql://postgres.csjruhqyqzzqxnfeyiaf@aws-1-eu-central-1.pooler.supabase.com:5432/postgres" \
  -c "SELECT * FROM events LIMIT 5;"

# Apply migration to production
PGPASSWORD="$SUPABASE_DB_PASSWORD_PROD" psql \
  "postgresql://postgres.csjruhqyqzzqxnfeyiaf@aws-1-eu-central-1.pooler.supabase.com:5432/postgres" \
  -f apps/web/supabase/migrations/YYYYMMDDHHMMSS_description.sql

Staging Database

# Load password from .env.local (or fetch from 1Password and cache)
source apps/web/.env.local 2>/dev/null
if [ -z "$SUPABASE_DB_PASSWORD_STAGING" ]; then
  SUPABASE_DB_PASSWORD_STAGING="$(op item get rkzjnr5ffy5u6iojnsq3clnmia --fields notesPlain --reveal)"
  echo "SUPABASE_DB_PASSWORD_STAGING=$SUPABASE_DB_PASSWORD_STAGING" >> apps/web/.env.local
fi

# Connect to staging
PGPASSWORD="$SUPABASE_DB_PASSWORD_STAGING" psql \
  "postgresql://postgres.hxpcknyqswetsqmqmeep@aws-1-eu-central-1.pooler.supabase.com:5432/postgres"

# Execute single query on staging
PGPASSWORD="$SUPABASE_DB_PASSWORD_STAGING" psql \
  "postgresql://postgres.hxpcknyqswetsqmqmeep@aws-1-eu-central-1.pooler.supabase.com:5432/postgres" \
  -c "SELECT * FROM events LIMIT 5;"

# Apply migration to staging
PGPASSWORD="$SUPABASE_DB_PASSWORD_STAGING" psql \
  "postgresql://postgres.hxpcknyqswetsqmqmeep@aws-1-eu-central-1.pooler.supabase.com:5432/postgres" \

Common Queries

Check Hire Order Status

SELECT
  ho.id,
  ho.order_number,
  ho.status,
  ho.dancer_approved_at,
  ho.estimated_total,
  ho.created_at,
  cr.role_name,
  e.title as event_title
FROM hire_orders ho
LEFT JOIN cast_roles cr ON ho.cast_role_id = cr.id
LEFT JOIN events e ON ho.event_id = e.id
WHERE ho.event_id = 'event-uuid'
ORDER BY ho.created_at DESC;

Check Event Participation

SELECT
  ep.id,
  ep.status,
  ep.created_at,
  p.first_name,
  p.last_name,
  p.email
FROM event_participants ep
LEFT JOIN profiles p ON ep.user_id = p.id
WHERE ep.event_id = 'event-uuid'
ORDER BY ep.created_at DESC;

Check Cast Assignments

SELECT
  ca.id,
  ca.assignment_status,
  ca.rate,
  cr.role_name,
  p.first_name,
  p.last_name
FROM cast_assignments ca
LEFT JOIN cast_roles cr ON ca.cast_role_id = cr.id
LEFT JOIN profiles p ON ca.user_id = p.id
WHERE ca.event_id = 'event-uuid';

Check RLS Policies for a Table

SELECT schemaname, tablename, policyname, permissive, roles, cmd, qual
FROM pg_policies
WHERE tablename = 'hire_orders';

Check Migration Status

SELECT version, name, statements
FROM supabase_migrations.schema_migrations
ORDER BY version DESC
LIMIT 20;

Recording Migrations After Manual Application

After applying a migration manually, record it in the tracking table:

INSERT INTO supabase_migrations.schema_migrations (version, name, statements)
VALUES ('YYYYMMDDHHMMSS', 'migration_name', ARRAY['SQL_STATEMENT'])
ON CONFLICT (version) DO NOTHING;

Safety Features

• Read-only by default: Prevents accidental data modification
• Credential management: Uses 1Password for secure credential storage
• Connection pooling: Uses Supabase pooler for reliable connections
• Query logging: All queries are logged for audit trail

Error Handling

1Password not authenticated:

op signin
# Follow authentication flow

psql not installed:

brew install postgresql@16

Connection timeout / "Tenant or user not found":

• Use aws-1-eu-central-1.pooler.supabase.com (not aws-0)
• Verify credentials in 1Password
• Check network connection

Best Practices

1. Test on staging first: Always test queries on staging before production
2. Read-only by default: Only use write operations when absolutely necessary
3. Limit results: Use LIMIT clause to avoid large result sets
4. Use transactions: For multiple queries, use transactions to ensure consistency
5. Log queries: Keep a record of production queries for audit purposes
6. Record migrations: After manual migration, always record in schema_migrations

MongoDB (Meteor Legacy) Database Access

The Ballee legacy Meteor app uses a MongoDB database hosted on Zerion (zcloud.ws). This is used for syncing data from the old community app.

MongoDB Credentials

Connection String Format

mongodb://root:<password>@mdb-p-0.ballee.db-eu2.zcloud.ws:60601,mdb-p-1.ballee.db-eu2.zcloud.ws:60602,mdb-p-2.ballee.db-eu2.zcloud.ws:60603/meteor?authSource=admin&ssl=true&tlsInsecure=true&replicaSet=mdb-p

Getting MongoDB URL

# From 1Password
op read "op://Private/Ballee Meteor MongoDB URL/password"

Meteor Sync CLI

For syncing data from MongoDB to Supabase staging, use the CLI tool:

# Set environment variables
export METEOR_SYNC_API_KEY="$(op read 'op://Private/Ballee Meteor Sync API Key/password')"
export STAGING_URL="https://ballee-git-feat-community-app-antoineschallers.vercel.app"

# Available commands
pnpm meteor:staging status    # Check MongoDB connection
pnpm meteor:staging history   # View sync history
pnpm meteor:staging trigger   # Trigger full sync
pnpm meteor:staging trigger --type incremental
pnpm meteor:staging trigger --entity organization
pnpm meteor:staging logs <runId>
pnpm meteor:staging stats
