Basic Check-ins Queries

This guide provides simple, ready-to-use SQL queries for Planning Center Check-ins data. Each query is designed to answer common ministry questions without requiring deep SQL knowledge.

Query Customization Required

These example queries demonstrate common patterns but may require adjustments to match your specific database schema and field names. Test thoroughly in your environment before use.

Query Requirements

Schema Prefix

IMPORTANT: All tables in the Planning Center Check-ins module live in the planning_center schema. Always prefix table names with planning_center. when writing queries. ✅ CORRECT: SELECT * FROM planning_center.checkins_checkins ❌ INCORRECT: SELECT * FROM checkins_checkins

Row Level Security (RLS)

Row Level Security automatically enforces:

tenant_organization_id – results limited to your organization
system_status – only active records returned by default

Skip manual filters for these columns—RLS already applies them and redundant predicates can slow queries or mask data:

❌ WHERE tenant_organization_id = 1
❌ WHERE system_status = 'active'

Focus your WHERE clauses on ministry-specific logic while trusting the database to keep tenant and status filters in place.

    DATE(created_at) as date,
    TO_CHAR(created_at, 'Day') as day_name,
    COUNT(*) as total_checkins
FROM planning_center.checkins_checkins
WHERE created_at >= CURRENT_DATE - INTERVAL '3 months'
GROUP BY DATE(created_at), TO_CHAR(created_at, 'Day')
ORDER BY total_checkins DESC
LIMIT 10;

Tips for Using These Queries

Dates: Replace CURRENT_DATE with specific dates like '2024-01-07' to query historical data
Limits: Add LIMIT 10 to any query to see just the first 10 results
Sorting: Change DESC to ASC if you want to reverse the sort order
Filtering: Add more WHERE conditions to narrow your results
