如何将sysdate添加到Oracle SQLPlus报告中的标题中？

Question

我正在尝试将sysdate放入SQLPlus报告的ttitle元素中，但我无法完全理解语法。

这就是我所知道的：

任何人都可以帮忙吗？

ttitle center 'This is my title' skip 2 left - 
       'prepared by a SQLPlus noob' right - 
       select sysdate from dual skip 4; 

Answer 1

您可以使用sqlplus中的new_value构造来执行此操作。

SQL> set feedback off; 
SQL> column a1 new_value report_date 
SQL> select sysdate report_date 
    2 from dual; 

SQL> spool "C:\report1.log" 
SQL> select * from scott.emp; 
SQL> spool off; 

报告输出
