SQL*Plus doesn't offer this feature out-of-the-box. You have to setup <a href="https://oracle-base.com/articles/linux/rlwrap" rel="noreferrer">rlwrap</a> to get that going

We have built a new command line interface that supports everything SQL*Plus offers, but also includes more modern features such as previous command history. It's called <a href="http://www.thatjeffsmith.com/archive/2015/02/oracle-sqlcl-slidedeck-overview-of-our-new-command-line-interface/" rel="noreferrer">SQLcl</a>. The command history remembers your last 100 statements/scripts, even from previous sessions.

If you need rerun only the last command typed then the forwardslash "/" would work.
Hit / and then the enter key would rerun the last statement.

in SQL plus command you can get you previous command by:

1- show previous command

<pre><code>SQL&gt; history 
 1 l
 2 show history
 3 select * from dual;
</code></pre>

2- run specific command from previous

<pre><code>SQL&gt; history 3 run

D
-
X
</code></pre>

3- edit specific command from previous

<pre><code>SQL&gt; history 2 edit
</code></pre>

PS: before using history you need to activated by:

<pre><code>SQL&gt; set history on
</code></pre>

I am using Oracle 10g Express Edition on Fedora core 5 32+ bit os. The problem is when I use the SQL Plus command line to make SQL statements I can not get the previously typed command back at the prompt when I use the up and down arrow keys on my keyboard. This is quite easy when I am using a shell, but here with this Oracle command line interface it is not working at all. Here is the example as what actually is happening whe I press the up or down arrow keys.

SQL> drop table mailorders;

Table dropped.

SQL> ^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A

SQL Plus command line: Arrow keys not giving previous commands back

我在Fedora核心5 32+位操作系统上使用Oracle10g Express Edition。问题是，当我使用SQL Plus命令行创建SQL语句时，当我使用键盘上的向上和向下箭头键时，无法在提示符处返回之前键入的命令。当我使用shell时，这非常容易，但是在这里，使用这个Oracle命令行界面，它根本不能工作。这...
