通过上一节内容,DriverEndpoint最终生成多个可执行的TaskDescription对象,并向各个ExecutorEndpoint发送LaunchTask指令,本节内容将关注ExecutorEndpoint如何处理LaunchTask指令,处理完成后如何回馈给DriverEndpoint,以及整个job最终如何多次调度直至结束。 一、... Python基础任务一 ...
execute()--执行sql语句 executemany--执行多条sql语句 close()--关闭游标 fetchone()--从结果中取一条记录,并将游标指向下一条记录 fetchmany()--从结果中取多条记录 fetchall()--从结果中取出所有记录 scroll()--游标滚动 下面就使用Python SQLITE数据库中游标对我们上面建立的数据库作一些操作吧: 1,建表...
