Cator

简介

封装了mysql和sqlite，用于零时执行一些脚本，如果项目中使用

安装

pip install cator

使用示例

import cator

# mysql
db_url = "mysql://root:123456@127.0.0.1:3306/data?charset=utf8&autocommit=true"

# sqlite
db_url = 'sqlite:///data.db?autocommit=true'

# open Database
db = cator.connect(db_url)

# close
db.close()

        pass

    def update(self, operation, params=()):
        pass

    def delete(self, operation, params=()):
        pass

    def insert(self, operation, params: Union[list, dict]):
        pass

    def insert_one(self, operation, params: Union[tuple, dict] = ()):
        pass

    def before_execute(self, operation, params=None):
        pass

    def after_execute(self, cursor):
        pass

    def execute(self, operation, params=None):
        pass

Table 类

class Table:

    @property
    def columns(self):

注意问题

1. 使用时需注意链接超时问题
2. cator支持了autocommit自动提交，默认关闭，如有需要可以打开，
3. 如果需要执行事务就需要关闭自动提交
