sql - 如何在Oracle中正确假脱机

Question

我创建了一个 spool 命令来将数据从 Oracle 导出到 csv 中。文件。这是:

    set echo off
    set verify off
    set feedback off
    set heading on
    set termout on
    set pages 50000
    set newpage none
    spool Y:\Marketing\Nick\OptivoList\test.csv
    Select EMAIL || ',' || ',' || GENDER
    from Email_test;
    spool off;
    exit;

它创建这样的输出:

EMAIL,GENDER

<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1c68796f682d5c68796f68327f7371" rel="noreferrer noopener nofollow">[email protected]</a>, M

问题 - 如何消除标题和数据之间的“----------”输出？

Answer 1

有两种方法 -

1. 关闭下划线

例如，

SQL> set underline off
SQL> select empno, ename from emp;

     EMPNO,ENAME
      7369,SMITH
      7499,ALLEN
      7521,WARD
      7566,JONES
      7654,MARTIN
      7698,BLAKE
      7782,CLARK
      7788,SCOTT
      7839,KING
      7844,TURNER
      7876,ADAMS
      7900,JAMES
      7902,FORD
      7934,MILLER

页面大小为 0 的自定义列标题

您需要将页面大小设置为零。这将抑制列标题和重复的列标题。然后，使用 UNION ALL 语句应用您的自定义列名称。

例如，

SQL> set pagesize 0
SQL> SELECT 'EMPNO' ||' , '|| 'ENAME' FROM DUAL
  2   UNION ALL
  3   SELECT EMPNO||' , '||ENAME FROM EMP
  4   /
EMPNO , ENAME
7369 , SMITH
7499 , ALLEN
7521 , WARD
7566 , JONES
7654 , MARTIN
7698 , BLAKE
7782 , CLARK
7788 , SCOTT
7839 , KING
7844 , TURNER
7876 , ADAMS
7900 , JAMES
7902 , FORD
7934 , MILLER

15 rows selected.
