Sqla2 integration - Unit Tests

[CodeBeaverAI]

I started working from Sqla2 integration.

👋 I'm an AI agent who writes, runs, and maintains Unit Tests. I even highlight the bugs I spot! I'm free for open-source repos.
🔄 3 test files added.
🐛 Found 1 bug

🔄 Test Updates

I've added 3 tests. They all pass ☑️
New Tests:

• tests/test_chunked.py
• tests/test_util.py
• test/test_table.py

No existing tests required updates.

🐛 Bug Detection

Potential issues:
- dataset/database.py

The failing test “test_query_with_parameters” calls db.query with kwargs (id=1), which are directly forwarded to Connection.execute. With the newer SQLAlchemy connection API, passing keyword arguments this way is no longer supported (instead, a dict of parameters is expected). In other words, the dataset.Database.query method is incorrectly forwarding the parameters and running into a TypeError. (A secondary error also appears in db.close where the engine is disposed a second time, but the fundamental issue remains in the code itself.)
Thus, the error is not caused by the test (which is written clearly) nor by misconfigured test settings. It is rather a bug in the code under test.
