Question

我目前正在尝试将sysdate放入SQLPlus报告的ttitle元素中，但我无法正确理解语法。

这就是我所要做的：

有人可以帮忙吗？

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

Answer 1

您可以在sqlplus中使用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;
