cursor

引子 这是测试环境存在了很久的问题。由于基础配置信息（如：代理人信息）不像生产环境有专人维护，常常会有数据过期，导致无法使用的情况。 而很多配置数据是在外围系统维护（如代理人信息，在销管系统）以往的解决办法： 1. 联系销售管理系统协助配置。 2. 审核通过后同步到核心，然后出单 问题点：因为需要其他人配合，有等待；碰到大量数据配置时对配置人员来说很麻烦。 1. 解决方案（版本1.1） 工具：数据库存过 思路：需要导入数据的表放在数据库中。遍历这些表，在遍历过程中先删除表中符合条件的数据，然后将生产环境符合条件的数据迁入到当前环境中 /*****************************************************************************\ * Name: P_IMPORT_CHA_DATA * PROCEDURE: 导生产环境基础数据（代理人信息） * Paramater: IC_C_CHA_CDE 代理人代码 * Programmer: lyt * Date: 2019/10/12 * Update: * 需导入表配置：T_IMPORT_TABLE WHERE C_MARK = '2'; * 维护dbquery中间库表结构：SELECT 'CREATE TABLE T_' || C_TABLE || ' AS SELECT *

Python操作三大主流数据库 Python 标准数据库接口为 Python DB-API，Python DB-API为开发人员提供了数据库应用编程接口。 Python 数据库接口支持非常多的数据库，你可以选择适合你项目的数据库： GadFly mSQL MySQL PostgreSQL Microsoft SQL Server 2000 Informix Interbase Oracle Sybase 不同的数据库你需要下载不同的 DB API模块，例如你需要访问Oracle数据库和Mysql数据，你需要下载Oracle和MySQL数据库模块。 DB-API 是一个规范. 它定义了一系列必须的对象和数据库存取方式, 以便为各种各样的底层数据库系统和多种多样的数据库接口程序提供一致的访问接口 。 Python的DB-API，为大多数的数据库实现了接口，使用它连接各数据库后，就可以用相同的方式操作各数据库。 Python DB-API使用流程： 引入 API 模块。 获取与数据库的连接。 执行 SQL语句和存储过程。 关闭数据库连接。 什么是 MySQLdb? MySQLdb 是用于Python链接Mysql数据库的接口，它实现了 Python 数据库 API 规范 V2.0，基于 MySQL C API 上建立的。 如何安装 MySQLdb? 为了用 DB-API编写MySQL脚本

After many attempts trying to make a JProgressBar work as expected, I finally became successful at achieving my goal. I had used @MadProgrammer 's advice and used a SwingWorker to finally get the program work as I want. Now, I want the cursor to change into when my JProgressBar goes from 0% to 100%. I've googled and found out that setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); is the code to do it. I've tried it but it does not work as expected. Relevant piece of code: JProgressBar progress; JButton button; JDialog dialog; //Fields of my GUI class progress=new JProgressBar

I just want to give you a little background Need to write a PL-SQL which will extract 6 million record joining different tables and create a file of that. Need more suggestions, specifically on how to fetch these many records. As fetching these million of records on a single go can be a highly resource intensive. So question is how to fetch these many records ? Any pl-sql will be highly appreciated. Do you need to extract the contents of a single table, or a JOIN result? Does the result have to be ordered? If so, you should first optimize your extraction query. Once you have an optimal query

Im on mac and I have my terminal cursor set to the vertical bar option. However in vim command mode the cursor is the vertical bar but it wont let me use hjkl to go to the end of the line, it always stops right before the end. This is especially annoying because you have to use the arrow keys in insert mode to make the cursor go the end of the line. Any fix would be appreciated eg: hello worl | d , what I want is hello world | I think you're looking for set virtualedit=onemore . From :help 'virtualedit' : A comma separated list of these words: block Allow virtual editing in Visual block mode.
