-## Use Covering Indexes to Avoid Table Lookups
-
-Covering indexes include all columns needed by a query, enabling index-only scans that skip the table entirely.
-
-**Incorrect (index scan + heap fetch):**
-
-```sql
-create index users_email_idx on users (email);
-
-- Must fetch name and created_at from table heap
-select email, name, created_at from users where email = 'user@example.com';
-```
-
-**Correct (index-only scan with INCLUDE):**
-
-```sql
-- Include non-searchable columns in the index
-create index users_email_idx on users (email) include (name, created_at);
-
-- All columns served from index, no table access needed
-select email, name, created_at from users where email = 'user@example.com';
-```
-
-Use INCLUDE for columns you SELECT but don't filter on:
-
-```sql
-- Searching by status, but also need customer_id and total
-create index orders_status_idx on orders (status) include (customer_id, total);
-
-select status, customer_id, total from orders where status = 'shipped';
-```
