Quick Start

from overdrive import OverdriveDb

odb = OverdriveDb.open("myapp.odb")

# Create table
odb.create_table("users")

# Insert — returns the generated _id
id = odb.insert("users", {"name": "Alice", "age": 30})

# Get by ID
doc = odb.get("users", id)
print(doc)  # {'_id': '...', 'name': 'Alice', 'age': 30}

# SQL Query
rows = odb.query("SELECT * FROM users WHERE age > 25")

# Update
odb.update("users", id, {"age": 31})

# Delete
odb.delete("users", id)

odb.close()

Context manager:

with OverdriveDb.open("myapp.odb") as odb:
    odb.create_table("users")
    id = odb.insert("users", {"name": "Bob"})
    print(odb.get("users", id))

    odb.commit_transaction(txn)
except Exception:
    odb.abort_transaction(txn)
    raise

Isolation Levels:

Name	Value
IsolationLevel.READ_UNCOMMITTED	0

IsolationLevel.SERIALIZABLE	3

Integrity Check

report = odb.verify_integrity()
print(report)  # {'status': 'ok', ...}
