oracle在现实世界中(oracle in the real world)

我最近在使用mysql几年后开始使用oracle。 我立刻被详细的oracle与mysql的比较感到震惊。 四字查询（如SHOW INDEX IN < table> ）在oracle中成为四行查询。

我的问题是： 真正的 oracle DBA如何有效地与oracle交互。 必须有一些方法来为常用命令添加别名（就像在unix shell中一样）。 我发现很难相信他们会输入类似的东西

select index_name, column_name, column_position from user_ind_columns where table_name='MYTABLENAME' order by index_name, column_position

每次他们想要做一些简单的事情就像列出表的索引一样。 否则他们怎么能完成任何工作？

I've recently started using oracle after a few years of using mysql. I was immediately struck by how verbose oracle is compared to mysql. Four-word queries (like SHOW INDEX IN < table> ) become four-line queries in oracle.

My question is: how do real oracle DBAs interact with oracle efficiently. There must be some way to alias commonly used commands (like you do in the unix shell). I find it hard to believe that they would type something like

select index_name, column_name, column_position from user_ind_columns where table_name='MYTABLENAME' order by index_name, column_position

every time they wanted to do something as simple as list the indexes of a table. Otherwise how can they get any work done?

您可以使用像SQL Developer或Toad这样的IDE; 它们具有用于浏览表，索引和其他对象的UI，而无需键入任何命令。

或者在SQL Plus中，您可以简单地将常用查询保存为文件中的脚本，例如，名为show_index的脚本可以包含：

select index_name, column_name, column_position from user_ind_columns where table_name=upper('&TABLENAME.') order by index_name, column_position;

你可以在SQL Plus中运行它，如下所示：

SQL> @show_index Enter value for tablename: mytable

You can use an IDE like SQL Developer or Toad; these have a UI to browse tables, indexes and other objects without typing any commands.

Or in SQL Plus you can simply save commonly used queries as scripts in files, for example a script called show_index could contain:

select index_name, column_name, column_position from user_ind_columns where table_name=upper('&TABLENAME.') order by index_name, column_position;

You would run this in SQL Plus like this:

SQL> @show_index Enter value for tablename: mytable
