Upsert in SQL is a combination of “insert” and “update” operations, enabling:
- Efficiency: Reduces the need for conditional checks before inserting or updating data.
- Simplicity: Streamlines data management by handling both insertion and updating in a single operation.
- Data Integrity: Helps maintain consistency by ensuring existing data is updated or new data is inserted appropriately.
- Concurrency: Facilitates concurrent access to data, minimizing conflicts in multi-user environments.
