ON [table]([column1]

[column2]);

-- Expected impact: [e.g.

converts full table scan to index seek]

- Covering Index — Includes all query columns

avoids table lookup

- Composite Index — Multiple columns

order matters

- B-Tree Index — Default

best for equality/range queries

- 🔴 Filesort — In-memory/disk sort

expensive

- ✅ Index Seek — Efficient

targeted lookup

6. ORDER BY : [Sort operation

filesort risk?]

- 🔴 Full Table Scan — No index used

highest cost

5. SELECT : [Column resolution

expressions evaluated]

2. WHERE : [Filters applied

index usage predicted]

- 🟡 Wildcard leading LIKE — e.g.

WHERE name LIKE '%john'

- 🟡 [Medium] — Moderate impact

best practice violation

- 📋 Sorting/Paging : ORDER BY

LIMIT/OFFSET requirements
