oracle select insite ksh使用colsep失败

我在ksh脚本中运行以下代码，它不会应用格式，即使我尝试手动添加它

ato_detail=`sqlplus -s /nolog <<EOF
connect xxx/xxxxx@xxxx
set feedback off
set pages 0
set termout off
set trimspool on
set colsep ','
spool tmp.log
spool ato_detail.log
select name,date, hism_logic_id from main_db.omp where type = 'ZW' and date >= sysdate-(48/24);
EOF`

---

ato_detail=`sqlplus-s/nolog将SQL部分放入
.SQL
文件中

test.sql

set feedback off
set pages 0
set termout off
set trimspool on
set colsep ','
spool tmp.log
spool ato_detail.log
select name,date, hism_logic_id from main_db.omp where type = 'ZW' and date >= sysdate-(48/24);

然后你可以试试-

#!/bin/ksh

sqlplus -s xxx/xxxxx@xxxx /nolog <<EOF
@test.sql
exit
EOF

#/bin/ksh
sqlplus-sxxx/xxxxx@xxxx/nolog你得到了什么，你期望得到什么？
