FastAPI - Database Integration

ACreate the session globally and reuse it for all requests

BDefine an async generator dependency using 'async with' to yield the async session

CUse a normal def function with yield for async sessions

DCall session.close() manually inside each async route

Step-by-Step Solution

Solution:

Step 1: Recognize async session management
Async SQLAlchemy sessions require async context management using 'async with' to open and close sessions properly.
Step 2: Implement async generator dependency
Using an async generator with 'async with' yields the session and ensures proper cleanup after use.
Final Answer:
Define an async generator dependency using 'async with' to yield the async session -> Option B
Quick Check:
Async sessions need async generator with 'async with' [OK]

Quick Trick: Use async generator and 'async with' for async sessions [OK]
