## 11. Common Join Patterns

```sql

SELECT t.id, t.title, c.company_name, 
       r.first_name || ' ' || r.last_name AS technician,
       s.label AS status_label, p.label AS priority_label
FROM tickets t
LEFT JOIN companies c ON c.id = t.company_id
LEFT JOIN resources r ON r.id = t.assigned_resource_id
LEFT JOIN statuses s ON s.value = t.status
LEFT JOIN priorities p ON p.value = t.priority
WHERE t.is_deleted IS NOT TRUE;

-- Time entries for a ticket
SELECT te.entry_date, te.hours_worked, te.notes,
       r.first_name || ' ' || r.last_name AS technician
FROM time_entries te
JOIN resources r ON r.id = te.resource_id
WHERE te.ticket_id = $1 AND te.is_deleted IS NOT TRUE;

-- RMM device → Autotask company
SELECT d.hostname, d.device_type_category, d.operating_system,
       s.autotask_company_name, d.online, d.last_seen
FROM datto_rmm_devices d
JOIN datto_rmm_sites s ON s.id = d.site_id;

-- Config item lookup (always filter by company too)
SELECT ci.id, ci.reference_title, ci.serial_number, c.company_name
FROM configuration_items ci
JOIN companies c ON c.id = ci.company_id
WHERE ci.reference_title = 'DT037' AND ci.company_id = $1;

-- IT Glue org → Autotask company
SELECT ig.name, ig.id AS itg_org_id, c.id AS autotask_company_id, c.company_name

FROM qbo_invoices
GROUP BY 1 ORDER BY 1 DESC;

-- QBO: Outstanding balances by customer
SELECT customer_ref_name, SUM(balance) AS outstanding
FROM qbo_invoices WHERE balance > 0
GROUP BY 1 ORDER BY 2 DESC;

-- Zabbix: Active WAN problems with company
SELECT ze.host_name, ze.trigger_name, ze.severity, ze.clock,
       c.company_name

## 12. Important Notes

1. **Soft deletes:** Most Autotask tables have `is_deleted` (boolean) and `deleted_at`. Always add `WHERE is_deleted IS NOT TRUE` unless you want deleted records.

2. **Picklist joins:** `status`, `priority`, `queue_id`, `source` on tickets are integer codes. Join to `statuses`, `priorities`, `queues` on `.value` for labels.

3. **Configuration item names are NOT unique globally.** Names like "DT037" are a per-client naming convention. Always pair with `company_id`.

4. **Timestamps:** Most Autotask timestamps are `timestamp without time zone` stored in UTC. Teams/Zoom timestamps are `timestamp with time zone`.

5. **Monitor tickets:** `tickets.source = 8` indicates RMM-generated tickets. `monitor_id` links to the specific Datto RMM monitor. These represent ~74% of all tickets.

6. **Cross-platform linking:**
   - RMM → Autotask: `datto_rmm_sites.autotask_company_id = companies.id`
   - IT Glue → Autotask: `itg_organizations.psa_id::bigint = companies.id`
   - S1 → Autotask: via `s1_company_mappings`
   - Zoom/Teams → Contacts: `matched_contact_id` / `matched_company_id` columns
   - Config Items → RMM: `configuration_items.reference_number` sometimes matches RMM device UIDs
