Oracle 如何从SQL*Plus结果中删除不必要的字符？,oracle,sqlplus,Oracle,Sqlplus,我正在寻找一种从SQL*Plus查询结果中删除所有不必要字符的方法仅供参考：我的公司要求我在这里发布问题之前隐藏任何数据，因此我已将所有列名替换为XXXXXX（字长保持不变），并将所有数据替换为DDDD。很抱歉这么做，但我不想惹麻烦；）首先：我想将所有SQL*Plus输出减少到两个示例中的一个第一个与PL/SQL Developer中的查询结果相同，如下所示： DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDD

我正在寻找一种从SQL*Plus查询结果中删除所有不必要字符的方法

仅供参考：我的公司要求我在这里发布问题之前隐藏任何数据，因此我已将所有列名替换为XXXXXX（字长保持不变），并将所有数据替换为DDDD。很抱歉这么做，但我不想惹麻烦；）
首先：我想将所有SQL*Plus输出减少到两个示例中的一个
第一个与PL/SQL Developer中的查询结果相同，如下所示：

DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D

XXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXX ------------------,------------------ XXXXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXX -------------------------------------------------------------------------------- XXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXXXXXXX ,XXXXXXXXX,X,XXXXXXXXX --------------------------------------------------,---------,-,--------- XXXXXXXXX,X,XXXXXXXXXXXX ,XXXXXXXXXXXXXXXX ---------,-,--------------------------------------------------,---------------- XXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXX ----------------,---------------- DDDD, DDDD

DDDDDDD, DDDDDDD DDDDDDD ,DDDDDDDDD,D,DDDDDDDDD DDDDDDDDD, ,DD , DDD DDD, D
第二种可能性（使用列名称，作为SQLPlus中的默认值）：

XXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXXXXXX,XXXXXXXXXXX,XXXXXXXXX, XXXX,XXXXXXXXXXXXXXXXXXX,XXXXXXXXX,X,XXXXXXXXX,XXXXXXXXX, X,XXXXXXXXXXXX,XXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXX ------------------,------------------,------------------------,----------------------,-----------,---------,------------,-------------------,---------,-,---------,---------,---,------------,----------------,----------------,---------------- DDDD, DDDD, DDDDDD, DDDDDDDDD, , ,DDDDDDDDDDDD, DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD,DDD, DDD, DDD, DDD, D
你已经掌握了基本知识。现在。对于当前的结果，我已经掌握了
纯SQLPlus结果，只需一次修改，即

set colsep ','
看起来像这样：

DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D

XXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXX ------------------,------------------ XXXXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXX -------------------------------------------------------------------------------- XXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXXXXXXX ,XXXXXXXXX,X,XXXXXXXXX --------------------------------------------------,---------,-,--------- XXXXXXXXX,X,XXXXXXXXXXXX ,XXXXXXXXXXXXXXXX ---------,-,--------------------------------------------------,---------------- XXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXX ----------------,---------------- DDDD, DDDD

DDDDDDD, DDDDDDD DDDDDDD ,DDDDDDDDD,D,DDDDDDDDD DDDDDDDDD, ,DD , DDD DDD, D
如您所见，这里有大量的------，我向您展示的结果仅涵盖了前两列的结果（DDDD，dddddd）。不需要粘贴所有结果，但它们看起来是一样的。列名和------的组合重复了很多次，只是为了覆盖一两个结果。这使得所有结果都完全无法读取
我已尝试对这组命令执行相同的操作：

set heading off set recsep off
我得到的结果接近我想要的…但仍然充满了不必要的空格和换行符（我假设换行符来自

linesize
财产
看起来是这样的：

DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D DDDD,DDDD,DDDDDD,DDDDDDDDD,,,DDDDDDDDDDDD,DDDDDDD,DDDDDDDDD,D,DDDDDDDDD,DDDDDDDDD, ,DDD,DDD,DDD,D

XXXXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXXXX ------------------,------------------ XXXXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXXXXXXXXXXXXXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXX -------------------------------------------------- XXXXXXXXX -------------------------------------------------------------------------------- XXXX -------------------------------------------------------------------------------- XXXXXXXXXXXXXXXXXXX ,XXXXXXXXX,X,XXXXXXXXX --------------------------------------------------,---------,-,--------- XXXXXXXXX,X,XXXXXXXXXXXX ,XXXXXXXXXXXXXXXX ---------,-,--------------------------------------------------,---------------- XXXXXXXXXXXXXXXX,XXXXXXXXXXXXXXXX ----------------,---------------- DDDD, DDDD

DDDDDDD, DDDDDDD DDDDDDD ,DDDDDDDDD,D,DDDDDDDDD DDDDDDDDD, ,DD , DDD DDD, D
有没有办法删除所有不必要的空格和换行符

为SQLPlus输出编写一个样式的最佳方法是什么，该样式将为不同的查询集生成至少可读的结果？
最简单的方法->只需连接输出（让您可以轻松地动态格式化日期和数字）

SQL*Plus
提供了许多
格式选项
。您可以选择相应地使用它们

SET LINESIZE 1000 SET ECHO OFF SET FEEDBACK OFF SET VERIFY OFF SET HEADING OFF SET TERMOUT OFF SET TRIMOUT ON SET TRIMSPOOL ON SET COLSEP | SET NEWPAGE NONE SET PAGESIZE 0 SET SPACE 0
让我们看一个演示
原始输出，没有任何格式
