📚 Usage
from flamel.base import Base
from flamel.column import Column, Integer, String
class Worker(Base):
id = Column("id", Integer, primary_key=True, autoincrement=True)
name = Column("name", String, nullable=False, unique=True)
email = Column("mail", String, nullable=False, unique=True)
Base.set_engine("company.db")
Base.create_tables()
import sqlite3
conn = sqlite3.connect("company.db")
cursor = conn.cursor()
cursor.execute("INSERT INTO Worker(name, mail) values ('John Doe', 'john.doe@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Jane Smith', 'jane.smith@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Mike Johnson', 'mike.johnson@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Alice Williams', 'alice.williams@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Bob Brown', 'bob.brown@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Charlie Davis', 'charlie.davis@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Eve Miller', 'eve.miller@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Frank Clark', 'frank.clark@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Grace White', 'grace.white@example.com')")
cursor.execute("INSERT INTO Worker(name, mail) values ('Henry Harris', 'henry.harris@example.com')")
conn.commit()
conn.close()
query = Worker.query().select().filter(name="John Doe")
print(query)
result = query.execute()
print(result)
Base.engine_close()
