SQLAlchemy Skill

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that provides the full power and flexibility of SQL. It consists of two main components: Core (SQL Expression Language) and ORM (Object Relational Mapper).

When to Use This Skill

Use SQLAlchemy when:

  • Working with relational databases in Python
  • Defining database models as Python classes
  • Building SQL queries programmatically
  • Managing database transactions and sessions
  • Mapping Python objects to database tables
  • Need database-agnostic code that works across PostgreSQL, MySQL, SQLite, etc.

Installation

pip install sqlalchemy

# For async support
pip install sqlalchemy[asyncio]

Engine and Connection

The Engine is the starting point for SQLAlchemy applications:

from sqlalchemy import create_engine

# SQLite (in-memory)
engine = create_engine("sqlite://", echo=True)

# SQLite (file-based)
engine = create_engine("sqlite:///mydatabase.db")

# PostgreSQL
engine = create_engine("postgresql+psycopg2://user:password@localhost/dbname")

# MySQL
engine = create_engine("mysql+pymysql://user:password@localhost/dbname")

# Connection pool settings
engine = create_engine(
    "postgresql+psycopg2://user:password@localhost/dbname",
    pool_size=5,           # Number of connections to keep open
    max_overflow=10,       # Additional connections allowed
    pool_timeout=30,       # Seconds to wait for connection
    pool_recycle=1800,     # Recycle connections after N seconds
)
Using Connections Directly (Core)
from sqlalchemy import text

with engine.connect() as conn:
    result = conn.execute(text("SELECT * FROM users WHERE id = :id"), {"id": 1})
    for row in result:
        print(row)

    # For write operations, commit explicitly
    conn.execute(text("INSERT INTO users (name) VALUES (:name)"), {"name": "Alice"})
    conn.commit()

ORM Declarative Mapping

from datetime import datetime
from typing import List, Optional

from sqlalchemy import ForeignKey, String, func
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column, relationship


class Base(DeclarativeBase):
    pass


class User(Base):
    __tablename__ = "user_account"

    # Primary key with auto-increment
    id: Mapped[int] = mapped_column(primary_key=True)

    # Required string column with max length
    name: Mapped[str] = mapped_column(String(30))

    # Optional column (nullable)
    fullname: Mapped[Optional[str]]

    # Column with default value
    created_at: Mapped[datetime] = mapped_column(default=func.now())

    # One-to-many relationship
    addresses: Mapped[List["Address"]] = relationship(
        back_populates="user",
        cascade="all, delete-orphan"
    )

    def __repr__(self) -> str:
        return f"User(id={self.id!r}, name={self.name!r})"


class Address(Base):
    __tablename__ = "address"

    id: Mapped[int] = mapped_column(primary_key=True)
    email_address: Mapped[str]
    user_id: Mapped[int] = mapped_column(ForeignKey("user_account.id"))

    # Many-to-one relationship (back reference)
    user: Mapped["User"] = relationship(back_populates="addresses")

    def __repr__(self) -> str:
        return f"Address(id={self.id!r}, email_address={self.email_address!r})"

Session and CRUD Operations

Session Basics
from sqlalchemy.orm import Session, sessionmaker

# Option 1: Direct Session usage
with Session(engine) as session:
    # ... operations
    session.commit()

# Option 2: Using sessionmaker (recommended for applications)
SessionFactory = sessionmaker(bind=engine)

with SessionFactory() as session:
    # ... operations
    session.commit()

# Option 3: With explicit begin/commit/rollback
with Session(engine) as session:
    with session.begin():
        # Automatically commits on success, rolls back on exception
        session.add(some_object)
Create (INSERT)
with Session(engine) as session:
    # Create single object
    user = User(name="alice", fullname="Alice Smith")
    session.add(user)

    # Create with related objects
    user_with_addresses = User(
        name="bob",
        fullname="Bob Jones",
        addresses=[
            Address(email_address="bob@example.com"),
            Address(email_address="bob@work.com"),
        ]
    )
    session.add(user_with_addresses)

    # Add multiple objects
    session.add_all([
        User(name="carol"),
        User(name="dave"),
    ])

    session.commit()
Read (SELECT)
from sqlalchemy import select

with Session(engine) as session:
    # Get by primary key
    user = session.get(User, 1)

    # Select all
    stmt = select(User)
    users = session.scalars(stmt).all()

    # Select with filter
    stmt = select(User).where(User.name == "alice")
    alice = session.scalars(stmt).first()

    # Select with multiple conditions
    stmt = select(User).where(
        User.name.like("a%"),
        User.id > 5
    )

    # Select specific columns
    stmt = select(User.name, User.fullname)
    rows = session.execute(stmt).all()
    for name, fullname in rows:
        print(f"{name}: {fullname}")

    # Order by
    stmt = select(User).order_by(User.name.desc())

    # Limit and offset
    stmt = select(User).limit(10).offset(20)

    # Count
    from sqlalchemy import func
    stmt = select(func.count()).select_from(User)
    count = session.scalar(stmt)
Update
with Session(engine) as session:
    # Update via ORM (load then modify)
    user = session.get(User, 1)
    user.fullname = "Alice Johnson"
    session.commit()

    # Bulk update
    from sqlalchemy import update
    stmt = update(User).where(User.name == "alice").values(fullname="Alice Updated")
    session.execute(stmt)
    session.commit()
Delete
with Session(engine) as session:
    # Delete via ORM
    user = session.get(User, 1)
    session.delete(user)
    session.commit()

    # Bulk delete
    from sqlalchemy import delete
    stmt = delete(User).where(User.name == "alice")
    session.execute(stmt)
    session.commit()

Relationships

One-to-Many / Many-to-One
class Parent(Base):
    __tablename__ = "parent"

    id: Mapped[int] = mapped_column(primary_key=True)
    children: Mapped[List["Child"]] = relationship(back_populates="parent")


class Child(Base):
    __tablename__ = "child"

    id: Mapped[int] = mapped_column(primary_key=True)
    parent_id: Mapped[int] = mapped_column(ForeignKey("parent.id"))
    parent: Mapped["Parent"] = relationship(back_populates="children")
One-to-One
class User(Base):
    __tablename__ = "user"

    id: Mapped[int] = mapped_column(primary_key=True)
    profile: Mapped["Profile"] = relationship(back_populates="user", uselist=False)


class Profile(Base):
    __tablename__ = "profile"

    id: Mapped[int] = mapped_column(primary_key=True)
    user_id: Mapped[int] = mapped_column(ForeignKey("user.id"), unique=True)
    user: Mapped["User"] = relationship(back_populates="profile")
Many-to-Many
from sqlalchemy import Column, Table

# Association table (no ORM class needed)
association_table = Table(
    "association",
    Base.metadata,
    Column("left_id", ForeignKey("left.id"), primary_key=True),
    Column("right_id", ForeignKey("right.id"), primary_key=True),
)


class Left(Base):
    __tablename__ = "left"

    id: Mapped[int] = mapped_column(primary_key=True)
    rights: Mapped[List["Right"]] = relationship(
        secondary=association_table,
        back_populates="lefts"
    )


class Right(Base):
    __tablename__ = "right"

    id: Mapped[int] = mapped_column(primary_key=True)
    lefts: Mapped[List["Left"]] = relationship(
        secondary=association_table,
        back_populates="rights"
    )
Association Object (Many-to-Many with extra data)
class Association(Base):
    __tablename__ = "association"

    left_id: Mapped[int] = mapped_column(ForeignKey("left.id"), primary_key=True)
    right_id: Mapped[int] = mapped_column(ForeignKey("right.id"), primary_key=True)
    extra_data: Mapped[Optional[str]]

    left: Mapped["Left"] = relationship(back_populates="right_associations")
    right: Mapped["Right"] = relationship(back_populates="left_associations")


class Left(Base):
    __tablename__ = "left"

    id: Mapped[int] = mapped_column(primary_key=True)
    right_associations: Mapped[List["Association"]] = relationship(back_populates="left")


class Right(Base):
    __tablename__ = "right"

    id: Mapped[int] = mapped_column(primary_key=True)
    left_associations: Mapped[List["Association"]] = relationship(back_populates="right")

Loading Strategies

Lazy Loading (Default)
# Lazy loading - queries database when attribute is accessed
user = session.get(User, 1)
# SELECT ... FROM user WHERE id = 1

addresses = user.addresses  # N+1 query problem!
# SELECT ... FROM address WHERE user_id = 1
Eager Loading with joinedload
from sqlalchemy.orm import joinedload

# Load user and addresses in single query using JOIN
stmt = select(User).options(joinedload(User.addresses)).where(User.id == 1)
user = session.scalars(stmt).unique().first()
# SELECT ... FROM user LEFT OUTER JOIN address ON ...
from sqlalchemy.orm import selectinload

# Load users, then load all addresses with IN clause
stmt = select(User).options(selectinload(User.addresses))
users = session.scalars(stmt).all()
# SELECT ... FROM user
# SELECT ... FROM address WHERE user_id IN (1, 2, 3, ...)
Raise on Lazy Load (Prevent N+1)
from sqlalchemy.orm import raiseload

# Raise error if lazy loading is attempted
stmt = select(User).options(raiseload(User.addresses))
user = session.scalars(stmt).first()
user.addresses  # Raises InvalidRequestError
Setting Default Loading Strategy
class User(Base):
    __tablename__ = "user"

    id: Mapped[int] = mapped_column(primary_key=True)
    # Always eager load addresses
    addresses: Mapped[List["Address"]] = relationship(lazy="selection")

Joins and Complex Queries

from sqlalchemy import select, and_, or_, func

# Explicit JOIN
stmt = (
    select(User, Address)
    .join(Address, User.id == Address.user_id)
    .where(User.name == "alice")
)

# JOIN using relationship
stmt = (
    select(

## Relationships

### One-to-Many / Many-to-One

```python
class Parent(Base):
    __tablename__ = "parent"

    id: Mapped[int] = mapped_column(primary_key=True)
    children: Mapped[List["Child"]] = relationship(back_populates="parent")


class Child(Base):
    __tablename__ = "child"

    id: Mapped[int] = mapped_column(primary_key=True)
    parent_id: Mapped[int] = mapped_column(ForeignKey("parent.id"))
    parent: Mapped["Parent"] = relationship(back_populates="children")
```

### One-to-One

```python
class User(Base):
    __tablename__ = "user"

    id: Mapped[int] = mapped_column(primary_key=True)
    profile: Mapped["Profile"] = relationship(back_populates="user", uselist=False)


class Profile(Base):
    __tablename__ = "profile"

    id: Mapped[int] = mapped_column(primary_key=True)
    user_id: Mapped[int] = mapped_column(ForeignKey("user.id"), unique=True)
    user: Mapped["User"] = relationship(back_populates="profile")
```

### Many-to-Many

```python
from sqlalchemy import Column, Table

# Association table (no ORM class needed)
association_table = Table(
    "association",
    Base.metadata,
    Column("left_id", ForeignKey("left.id"), primary_key=True),
    Column("right_id", ForeignKey("right.id"), primary_key=True),
)


class Left(Base):
    __tablename__ = "left"

    id: Mapped[int] = mapped_column(primary_key=True)
    rights: Mapped[List["Right"]] = relationship(
        secondary=association_table,
        back_populates="lefts"
    )


class Right(Base):
    __tablename__ = "right"

    id: Mapped[int] = mapped_column(primary_key=True)
    lefts: Mapped[List["Left"]] = relationship(
        secondary=association_table,
        back_populates="rights"
    )
```

### Association Object (Many-to-Many with extra data)

```python
class Association(Base):
    __tablename__ = "association"

    left_id: Mapped[int] = mapped_column(ForeignKey("left.id"), primary_key=True)
    right_id: Mapped[int] = mapped_column(ForeignKey("right.id"), primary_key=True)
    extra_data: Mapped[Optional[str]]

    left: Mapped["Left"] = relationship(back_populates="right_associations")
    right: Mapped["Right"] = relationship(back_populates="left_associations")


class Left(Base):
    __tablename__ = "left"

    id: Mapped[int] = mapped_column(primary_key=True)
    right_associations: Mapped[List["Association"]] = relationship(back_populates="left")


class Right(Base):
    __tablename__ = "right"

    id: Mapped[int] = mapped_column(primary_key=True)
    left_associations: Mapped[List["Association"]] = relationship(back_populates="right")
```

## Loading Strategies

### Lazy Loading (Default)

```python
# Lazy loading - queries database when attribute is accessed
user = session.get(User, 1)
# SELECT ... FROM user WHERE id = 1

addresses = user.addresses  # N+1 query problem!
# SELECT ... FROM address WHERE user_id = 1
```

### Eager Loading with joinedload

```python
from sqlalchemy.orm import joinedload

# Load user and addresses in single query using JOIN
stmt = select(User).options(joinedload(User.addresses)).where(User.id == 1)
user = session.scalars(stmt).unique().first()
# SELECT ... FROM user LEFT OUTER JOIN address ON ...
```

### Eager Loading with selectinload (Recommended)

```python
from sqlalchemy.orm import selectinload

# Load users, then load all addresses with IN clause
stmt = select(User).options(selectinload(User.addresses))
users = session.scalars(stmt).all()
# SELECT ... FROM user
# SELECT ... FROM address WHERE user_id IN (1, 2, 3, ...)
```

### Raise on Lazy Load (Prevent N+1)

```python
from sqlalchemy.orm import raiseload

# Raise error if lazy loading is attempted
stmt = select(User).options(raiseload(User.addresses))
user = session.scalars(stmt).first()
user.addresses  # Raises InvalidRequestError
```

### Setting Default Loading Strategy

```python
class User(Base):
    __tablename__ = "user"

    id: Mapped[int] = mapped_column(primary_key=True)
    # Always eager load addresses
    addresses: Mapped[List["Address"]] = relationship(lazy="selection")
```

## Joins and Complex Queries

```python
from sqlalchemy import select, and_, or_, func

# Explicit JOIN
stmt = (
    select(User, Address)
    .join(Address, User.id == Address.user_id)
    .where(User.name == "alice")
)

# JOIN using relationship
stmt = (
    select(
