I want to add Snowflake hybrid tables to my database schema using SQLAlchemy.
hybrid tables
Per this issue, support for hybrid tables is not implemented in the Snowflake SQLAlchemy official dialect.
this issue
Is there a way for me to customize the CREATE TABLE ... statement generated by SQLAlchemy so that it actually generates CREATE HYBRID TABLE ... for a given table?
CREATE TABLE ...
CREATE HYBRID TABLE ...
Consider the example code below:
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column
class Base(DeclarativeBase):
pass
class MyTable(Base):
id: Mapped[int] = mapped_column(primary_key=True)
Base.metadata.create_all(bind=...)
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column
class Base(DeclarativeBase):
pass
class MyTable(Base):
id: Mapped[int] = mapped_column(primary_key=True)
Base.metadata.create_all(bind=...)
Running it will emit the following SQL statement:
CREATE TABLE mytable (
id INTEGER NOT NULL AUTOINCREMENT,
CONSTRAINT pk_mytable PRIMARY KEY (id)
)
CREATE TABLE mytable (
id INTEGER NOT NULL AUTOINCREMENT,
CONSTRAINT pk_mytable PRIMARY KEY (id)
)
and I would like a way to have the following instead:
CREATE HYBRID TABLE mytable (
id INTEGER NOT NULL AUTOINCREMENT,
CONSTRAINT pk_mytable PRIMARY KEY (id)
)
CREATE HYBRID TABLE mytable (
id INTEGER NOT NULL AUTOINCREMENT,
CONSTRAINT pk_mytable PRIMARY KEY (id)
)
