在SQLalchemy中只考虑日期而不考虑时间的连接日期

from sqlalchemy import create_engine, Date
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

# 创建数据库连接
engine = create_engine('数据库连接字符串')
Session = sessionmaker(bind=engine)
session = Session()

# 创建基类
Base = declarative_base()

# 定义模型类
class MyModel(Base):
    __tablename__ = 'my_table'
    id = Column(Integer, primary_key=True)
    date_column = Column(Date)

# 提取日期部分并进行连接查询
date_to_compare = '2022-01-01'
query = session.query(MyModel).filter(func.DATE(MyModel.date_column) == date_to_compare)

# 执行查询
results = query.all()

# 处理查询结果
for result in results:
    print(result.id, result.date_column)

# 关闭数据库连接
session.close()
