其實很簡單，只要根據原始資料的格式，在控制檔案中欄位名後面加上日期格式字串就行了。例如：

load data
infile '訂單1012-1031.csv'
append into table emsapp_zywl_ddmx
fields terminated by ','
optionally enclosed by '"'
(ddh,xqdh,lsrq date 'YYYY-MM-DD hh24:mi:ss',lsjg,sfj,jsj,wpzl,wptj,wpjs,smjz,psfs,zzfw,mdqx,mdcs,mdsf,sfqx,sfcs,sfsf)

其中lsrq就是日期欄位，內容是日期和24小時制的時間，如：

2017-10-12  15:00:31

這個控制檔案由下面的shell指令碼生成，本指令碼負責將指定目錄下的csv檔案匯入資料庫中：

BAKDIR=/home/oracle/ems_zywl  
CTLFILE=control.ctl 
 
cd ${BAKDIR}  
for csvfile in *.csv  
do  
  # process csvfile  
  echo  ${csvfile}  
#  read -p "csv file: press enter to continue..." var  
   if [ -f ${csvfile} ]; then
     # generate control file
     echo load data>${CTLFILE}
     echo infile "'"${csvfile}"'">>${CTLFILE}
     echo append into table emsapp_zywl_ddmx>>${CTLFILE}
     echo fields terminated by "','">>${CTLFILE}
     echo optionally enclosed by "'\"'">>${CTLFILE}
     echo "(ddh,xqdh,lsrq date 'YYYY-MM-DD hh24:mi:ss',lsjg,sfj,jsj,wpzl,wptj,wpjs,smjz,psfs,zzfw,mdqx,mdcs,mdsf,sfqx,sfcs,sfsf)">>${CTLFILE}
     # import data
     sqlldr userid=emssxjk/emssxjk control=control.ctl skip=1
     mv ${csvfile} all_csv  
   fi
done
