列标题在整个 Oracle 输出中不断出现

每 10 行之后，我的列标题就会重新出现在 Oracle 输出中。我的代码或某种环境变量是否可以设置来阻止这种情况？我只需要列标题在结果顶部出现一次。

BREAK ON Customer
COLUMN Customer -
       FORMAT A15 -
       HEADING 'Customer Name'
COLUMN "Charter Date" -
       HEADING 'Charter|Date'
COLUMN Pilot -
       FORMAT A20 -
       HEADING 'Pilot'
SELECT DECODE (cu.cus_initial,null, cu.cus_fname||' '||cu.cus_lname,
       cu.cus_fname||' '||cu.cus_initial||'. '||cu.cus_lname)
       AS Customer,
       ch.char_date "Charter Date",
       TRIM( e.emp_fname) ||' '|| TRIM(e.emp_lname) AS "Pilot"
FROM hartmar.customer cu,
     hartmar.charter ch,
     hartmar.crew cr,
     hartmar.pilot p,
     hartmar.employee e
WHERE cu.cus_code = ch.cus_code
      AND ch.char_trip = cr.char_trip
      AND cr.emp_num = p.emp_num
      AND p.emp_num = e.emp_num
      AND cr.crew_type = 'Pilot'
ORDER BY cu.cus_lname, cu.cus_fname, cu.cus_initial, ch.char_date
;

After ever 10 lines, my column headers reappear in my Oracle output. Is there something about my code or some kind of environment variable I can set to stop this? I only need the column headers to appear once at the top of my results.

BREAK ON Customer
COLUMN Customer -
       FORMAT A15 -
       HEADING 'Customer Name'
COLUMN "Charter Date" -
       HEADING 'Charter|Date'
COLUMN Pilot -
       FORMAT A20 -
       HEADING 'Pilot'
SELECT DECODE (cu.cus_initial,null, cu.cus_fname||' '||cu.cus_lname,
       cu.cus_fname||' '||cu.cus_initial||'. '||cu.cus_lname)
       AS Customer,
       ch.char_date "Charter Date",
       TRIM( e.emp_fname) ||' '|| TRIM(e.emp_lname) AS "Pilot"
FROM hartmar.customer cu,
     hartmar.charter ch,
     hartmar.crew cr,
     hartmar.pilot p,
     hartmar.employee e
WHERE cu.cus_code = ch.cus_code
      AND ch.char_trip = cr.char_trip
      AND cr.emp_num = p.emp_num
      AND p.emp_num = e.emp_num
      AND cr.crew_type = 'Pilot'
ORDER BY cu.cus_lname, cu.cus_fname, cu.cus_initial, ch.char_date
;

假设您在 SQL*Plus 中运行它，您需要设置页面大小。

SET PAGESIZE 50000

将导致每返回 50,000 行，列标题仅出现一次。我相信 50,000 是最大 PAGESIZE 设置。

如果您想完全消除标头，可以将 PAGESIZE 设置为 0，但这甚至会抑制第一组标头

SQL> set pagesize 0;
SQL> select ename, empno from emp;
PAV              7623
smith            7369
ALLEN            7499
WARD             7521
JONES            7566
MARTIN           7654
BLAKE            7698
CLARK            7782
SCOTT            7788
KING             7839
TURNER           7844
ADAMS            7876
SM0              7900
FORD             7902
MILLER           7934
BAR              1234

16 rows selected.

Assuming you're running this in SQL*Plus, you need to set your pagesize.

SET PAGESIZE 50000

will cause the columns headings to appear only once for every 50,000 rows returned. I believe 50,000 is the maximum PAGESIZE setting.

If you want to eliminate headers entirely, you can set the PAGESIZE to 0 but that will suppress even the first set of headers

SQL> set pagesize 0;
SQL> select ename, empno from emp;
PAV              7623
smith            7369
ALLEN            7499
WARD             7521
JONES            7566
MARTIN           7654
BLAKE            7698
CLARK            7782
SCOTT            7788
KING             7839
TURNER           7844
ADAMS            7876
SM0              7900
FORD             7902
MILLER           7934
BAR              1234
