从SQL * PLUS假脱机的csv文件中删除尾随空格

Question

我有一个简单的SQL脚本，它从一组表中返回一些数据，然后使用SQL*PLUS将数据假脱机到csv。

脚本

SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET TERMOUT OFF
SET HEADING OFF
SET TAB OFF
SET COLSEP ''
SET PAGESIZE 0 
SET LINESIZE 32767 
SET SQLBLANKLINE ON
SET TRIMSPOOL ON
SET TRIMS ON

SPOOL "C:\output.csv"

PROMPT "ID","PERSON","STUDY_ID","START_DATE","END_DATE","STATUS","PROGRESS_STATUS","AMOUNT","DATE","WITHDRAWN","SPARE"

SELECT 
       '"' || TRIM(ID)              || '"'
    ||',"' || TRIM(PERSON)          || '"'
    ||',"' || TRIM(STUDY_ID)        || '"'
    ||',"' || TRIM(START_DATE)      || '"'
    ||',"' || TRIM(END_DATE)        || '"'
    ||',"' || TRIM(STATUS)          || '"'
    ||',"' || TRIM(PROGRESS_STATUS) || '"'
    ||',"' || TRIM(AMOUNT)          || '"'
    ||',"' || TRIM("DATE")          || '"'
    ||',"' || TRIM(WITHDRAWN)       || '"'
    ||',"' || TRIM(SPARE)           || '"'
FROM
(   
    SELECT DISTINCT

        A.ID,
        A.PERSON,
        A.STUDY_ID,
        A.START_DATE,
        A.END_DATE,
        A.STATUS,
        A.PROGRESS_STATUS,
        A.AMOUNT,
        "DATE",
        A.WITHDRAWN,
        TO_CHAR(COALESCE(A.ID, A.UI_ID) || '-' || COALESCE(B.PARENTID, B.ID)) AS SPARE

    FROM SOME_TABLE A
    LEFT JOIN SOME_OTHER_TABLE B ON B.ID = A.OTHER_ID

)
;

SPOOL OFF

SET FEEDBACK ON
SET VERIFY ON
SET TERMOUT ON
SET HEADING ON
SET TAB ON
SET SQLBLANKLINE OFF
SET TRIMSPOOL OFF
SET TRIMS OFF
SET ESCAPE OFF

我遇到的问题是我期望的csv文件的数据假脱机，但最后一列包含尾随空格。如何更改设置以删除尾随空格？
