hard🚀 Application Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Understand batch insertion
executemany() allows inserting many rows efficiently in one call.Step 2: Compare other methods
Repeated execute() calls are slower; raw SQL concatenation risks errors and injection; no commit delays saving.Final Answer:
Use cursor.executemany() with a list of tuples -> Option DQuick Check:
Batch insert with executemany() is efficient [OK]
Quick Trick: Use executemany() for multiple inserts efficiently [OK]
Common Mistakes:
MISTAKES- Using execute() in loops without executemany()
- Concatenating SQL strings unsafely
- Forgetting to commit after inserts
