I am using SQLAlchemy ORM with a SQLite database, and many of my tables will have a simple integer primary key, with lots of foreign keys referencing them. It should improve efficiency if that integer primary key was the alias for the ROWID that you get by defining the column as INTEGER PRIMARY KEY, but it seems that with a definition of:
class Language(Base): """Define Language Table.""" __tablename__ = "Language" lang_id = Column(Integer, primary_key=True) lang_code = Column(String(20), unique=True) I get as the DDL: CREATE TABLE "Language" ( lang_id INTEGER NOT NULL, lang_code VARCHAR(20), CONSTRAINT "pk_Language" PRIMARY KEY (lang_id), CONSTRAINT "uq_Language_lang_code" UNIQUE (lang_code) ) which does not (at least appear to) create the needed primary key that is an alias for the ROWID. I can't seem to find anything documented to do to make this happen. I would think this would be a commonly wanted optimization. Is there something I can do to get this? I would like to be able to use the ORM. -- Richard Damon -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
