一,Execution Tree 执行树是数据流组件(转换和适配器)基于同步关系所建立的逻辑分组,每一个分组都是一个执行树的开始和结束,也可以将执行树理解为一个缓冲区的开始和结束,即缓冲区的整个生命周期. 大家知道,异步转换组件会结束输入缓冲区,创建新的输出缓冲区,所以,执行树的分组实际上通过异步转换组件来划分的,一个异步转换组件意味着上游执行树的结束和下游执行树的开始.当数据流经过异步转换组件,进入一个新的执行树,上一个执行树的缓冲区和相同数据就不再需要了,因为数据已经被传递到一个新的执行树和
select into outfile用法 SELECT ... FROM TABLE_A INTO OUTFILE "/path/to/file" FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'; MySQL中,可以使用SELECT...INTO OUTFILE语句将表的内容导出为一个文本文件.其基本的语法格式如下: SELECT [列名] FROM table [WH
