Sql 在Oracle中如何在命令行中设计输出？

这是我得到的答案。我试图更改设置页面，但仍然有两行：

REG#       FNAME
---------- --------------------------------------------------
LNAME
--------------------------------------------------
SST005     John
Lucas

PKR008     John
Lucas

PKR768     John
Lucas


    REG#       FNAME
    ---------- --------------------------------------------------
    LNAME
    --------------------------------------------------
    QRT834     John
    Lucas

    PKR008     John
    Lucas

    LUCY02

如何仅在一行中打印每行。这是我的剧本：

SELECT TRUCK.REG# , EMPLOYEE.FNAME, EMPLOYEE.LNAME
FROM TRUCK
LEFT OUTER JOIN TRIP
ON TRUCK.REG# = TRIP.REG# 
LEFT OUTER JOIN DRIVER
ON DRIVER.L# = TRIP.L#
LEFT OUTER JOIN EMPLOYEE
ON EMPLOYEE.E# = DRIVER.E#
;

在脚本中使用SQL*Plus命令：

set pagesize 0 -- SET PAGESIZE number_of_lines
set heading off -- No headers
set linesize 200 -- Line size 
etc.
