sqlalchemy Integer column size

Question

I saw somewhere that you can define a column size for Integer columns (e.g. Integer(20), Integer(10), etc.) but for some reason, it seems that sqlalchemy ignore those sizes

Answer 1

This functionality was deprecated in version 7.

If you are using MySQL, you can use the mysql.INTEGER datatype:

from sqlalchemy.dialects import mysql 

class Job(Base):
    __tablename__ = "t_job"

    id = Column(mysql.INTEGER(20), Sequence('%s_id_seq' % __tablename__), primary_key=True, nullable=False)
    name = Column(String(30))
    company_id = Column(Integer(20), ForeignKey("t_company.id", ondelete="CASCADE"), nullable=False)
