这是我的数组：

orlist=""
orlist="T_TAB1 \n"
orlist=$orlist"T_TAB2 \n"
orlist=$orlist"T_TAB3 \n"
orlist=$orlist"T_TAB4 \n"
echo $orlist
arrIdx=0
OLD_IFS=$IFS;
IFS="\n"
for IndixList in ${orlist[@]};
do
     echo $IndxList
     MYDIR[${arraryIndix}]=$IndixList
    (( arraryIndix = $arraryIndix+ 1 ))
done
IFS=$OLD_IFS

我必须在 for 循环内的 oracle db 中执行 SELECT，所以我必须按选项卡读取 $orlist 选项卡。我已经尝试过了，但它不起作用它需要整个数组而不是一个标签一个标签：

for arraryIndix in ${orlist[@]};
do

  echo "SET HEADING OFF"       >> ${FILEOR_SQL}
  echo "SET TERMOUT OFF"       >> ${FILEOR_SQL}
  echo "SET PAGESIZE 0"        >> ${FILEOR_SQL}
  echo "SET LINESIZE 1000"     >> ${FILEOR_SQL}
  echo "SET FEEDBACK OFF"      >> ${FILEOR_SQL}
  echo "SET TRIMSPOOL ON"      >> ${FILEOR_SQL}
  echo "SPOOL ${FILE_DAT}"     >> ${FILEOR_SQL}
  echo "SELECT * "             >> ${FILEOR_SQL}
  echo "FROM ${orlist[@]}"     >> ${FILEOR_SQL}
  echo "WHERE REP_ARG = 2; "   >> ${FILEOR_SQL}
  echo "SPOOL OFF"             >> ${FILEOR_SQL}
  echo "COMMIT;"               >> ${FILEOR_SQL}
  echo "SET HEADING ON"        >> ${FILEOR_SQL}
  echo "SET TERMOUT ON"        >> ${FILEOR_SQL}
  echo "SET PAGESIZE 14"       >> ${FILEOR_SQL}
  echo "SET FEEDBACK ON"       >> ${FILEOR_SQL}
  echo "SET TRIMSPOOL OFF"     >> ${FILEOR_SQL}
  echo "EXIT;"                 >> ${FILEOR_SQL}

  sqlplus -S -L ${Connection} @${FILEOR_SQL} #connection is a var for connect with `sqlplus`

done

有什么建议么？提前致谢

不要多次调用 sqlplus，而是让 SQL 脚本包含所有查询：

cat < END1 > ${FILEOR_SQL}
SET HEADING OFF
SET TERMOUT OFF
SET PAGESIZE 0
SET LINESIZE 1000
SET FEEDBACK OFF
SET TRIMSPOOL ON
SPOOL ${FILE_DAT}
END1

orlist=(T_TAB1 T_TAB2 T_TAB3 T_TAB4)

for table in "${orlist[@]}"; do
    echo "SELECT * FROM $table WHERE REP_ARG = 2;" >> ${FILEOR_SQL}
done

echo "QUIT" >> ${FILEOR_SQL}
sqlplus -S -L ${Connection} @${FILEOR_SQL}

那么你的问题来了，因为如果你写\n，它不一定被视为一个新行，有人必须将\后面的序列翻译n为一个换行符。在IFS="\n"IFS 中也需要设置为换行符，而不是\and的组合n。orlist 也是一个变量，您没有将它用作数组，并且在 for 循环中，它不会被视为数组。我做了一些改变，它似乎工作正常

#!/usr/local/bin/ksh
orlist=""
orlist="T_TAB1 \n"
orlist=$orlist"T_TAB2 \n"
orlist=$orlist"T_TAB3 \n"
orlist=$orlist"T_TAB4 \n"
echo  $orlist
arrIdx=0
OLD_IFS=$IFS;
IFS=$'\n'
#IFS=""
arraryIndix=0
for IndxList in `echo -e $orlist`
do
     echo "Hello $IndxList "
     MYDIR[${arraryIndix}]=$IndxList
    ((arraryIndix++))
done
IFS=$OLD_IFS
echo "Finally ${MYDIR[@]}"

输出

T_TAB1 \nT_TAB2 \nT_TAB3 \nT_TAB4 \n
Hello T_TAB1
Hello T_TAB2
Hello T_TAB3
Hello T_TAB4
Finally T_TAB1  T_TAB2  T_TAB3  T_TAB4
